Abstract
Benzyl butyl phthalate (BBP) and bisphenol-A (BPA) are obesogens that have been reported to be associated with obesity. Inhibition of their adipogenic activity could decrease the risk of obesity-related metabolic disorders. This study hypothesized that Anoectochilus burmannicus ethanolic extract (ABE) which has been previously reported its anti-inflammation property and its known active compound, kinsenoside (Kin) abrogate BBP- and BPA-induced adipogenesis. ABE and Kin markedly suppress both BBP- and BPA-stimulated adipogenesis with different modulations on adipogenic-gene expression including C/EBPα, PPARγ, adiponectin, and leptin in 3T3-L1. BBP induced C/EBPα, adiponectin, and leptin mRNA expressions and slightly increased PPARγ mRNA level, whereas BPA markedly induced PPARγ and adiponectin mRNA levels. ABE significantly decreased the expression of C/EBPα and leptin, but not PPARγ and adiponectin in the BBP-treated cells. In the BPA-treated cells, ABE significantly decreased the mRNA expression of C/EBPα and PPARγ, but not adiponectin and leptin. Interestingly, Kin significantly overcame BBP- and BPA-induced C/EBPα, PPARγ, adiponectin, and leptin expressions. This study first provides evidence to support the health benefits of this plant, especially for people exposed to obesogens. Besides, this finding would encourage the conservation and culture of this orchid for development as an economic plant and healthy food.

Abstract
Anoectochilus burmannicus is an orchid that contains phenolic compounds and exhibits antioxidant and anti-inflammation properties. This study aimed to investigate whether its ethanolic extract (ABE) can be used as a reducing agent and/or a stabilizer of nano-selenium (SeNP) synthesis. SeNPs exhibited higher antioxidant activity than ABE-SeNPs. In contrast, ABE-SeNP (4 µM Se) had greater anti-inflammatory activity in LPS-induced macrophages than SeNPs. Interestingly, ABE acted as a stabilizer for SeNPs by preventing particle aggregation and preserving its antioxidant activity after long-term storage (90 days). Moreover, after the freeze-drying process, ABE-SeNPs could be completely reconstituted to suspension with significantly stable antioxidant and anti-inflammatory activities compared to freshly prepared particles, suggesting the cryoprotectant and/or lyoprotectant role of ABE. The present study shows the potential of ABE as an effective stabilizer for nanoparticles and provides evidence for the development of ABE-SeNPs as a food supplement or novel functional ingredient for health benefits.

Abstract
Extensive research has implicated inflammation and oxidative stress in the development of multiple diseases, such as diabetes, hepatitis, and arthritis. Kinsenoside (KD), a bioactive glycoside component extracted from the medicinal plant Anoectochilus roxburghii, has been shown to exhibit potent anti-inflammatory and anti-oxidative abilities. In this review, we summarize multiple effects of KD, including hepatoprotection, pro-osteogenesis, anti-hyperglycemia, vascular protection, immune regulation, vision protection, and infection inhibition, which are partly responsible for suppressing inflammation signaling and oxidative stress. The protective action of KD against dysfunctional lipid metabolism is also associated with limiting inflammatory signals, due to the crosstalk between inflammation and lipid metabolism. Ferroptosis, a process involved in both inflammation and oxidative damage, is potentially regulated by KD. In addition, we discuss the physicochemical properties and pharmacokinetic profiles of KD. Advances in cultivation and artificial synthesis techniques are promising evidence that the shortage in raw materials required for KD production can be overcome. In addition, novel drug delivery systems can improve the in vivo rapid clearance and poor bioavailability of KD. In this integrated review, we aim to offer novel insights into the molecular mechanisms underlying the therapeutic role of KD and lay solid foundations for the utilization of KD in clinical practice.

Abstract
Kinsenoside is the major bioactive component from herbal medicine with a broad range of pharmacological functions. Goodyeroside A, an epimer of kinsenoside, remains less explored. In this report we chemically synthesized kinsenoside, goodyeroside A and their analogues with glycan variation, chirality inversion at chiral center(s), and bioisosteric replacement of lactone with lactam. Among these compounds, goodyeroside A and its mannosyl counterpart demonstrated superior anti-inflammatory efficacy. Furthermore, goodyeroside A was found to suppresses inflammatory through inhibiting NF-κB signal pathway, effectively. Structure-activity relationship is also explored for further development of more promising kinsenoside analogues as drug candidates.

Abstract
INTRODUCTION Kinsenoside is a characteristic component of Anoectochilus roxburghii and accounts for this herb's medicinal and edible values. No international certified standard method is available for kinsenoside analysis as well as extraction and preservation. OBJECTIVE To develop a more accurate analytical method of kinsenoside. The effects of extraction and drying methods of A. roxburghii on kinsenoside efficiency were investigated for the first time, as well as to examine the kinsenoside stability. MATERIAL AND METHODS The amino (NH2 ) and AQ-C18 columns for detecting kinsenoside extract was systematically compared by high-performance liquid chromatography evaporative light-scattering detector (HPLC-ELSD) and HPLC-diode-array detector (DAD), respectively. Kinsenoside, its epimer goodyeroside A and the degradation product during preservation were identified through HPLC-electrospray ionization mass spectrometry (ESI-MS). RESULTS An accurate method of kinsenoside detection by HPLC-ELSD with dual columns of NH2 and AQ-C18 was established. The ratio of Cgoodyeroside A to Ckinsenoside (Y) was determined using the AQ-C18 column method. The concentration detected by the NH2 column was multiplied by 1/(1 + Y) as the corrected result. Using this novel method, the average deviations were reduced by 7.64%. Moreover, the efficiency of kinsenoside extraction with water was almost twice that of extraction with ethanol. Freeze drying also led to a higher extraction efficiency (38.47% increase) than hot-air drying did. Furthermore, the degradation of kinsenoside extract exceeded 70% when stored at 37 °C for 3 months. CONCLUSION This study provides a reliable experimental method and theoretical basis for the quality control of kinsenoside from A. roxburghii, as well as other glycosides.

Abstract
This is an extensive review on epiphytic plants that have been used traditionally as medicines. It provides information on 185 epiphytes and their traditional medicinal uses, regions where Indigenous people use the plants, parts of the plants used as medicines and their preparation, and their reported phytochemical properties and pharmacological properties aligned with their traditional uses. These epiphytic medicinal plants are able to produce a range of secondary metabolites, including alkaloids, and a total of 842 phytochemicals have been identified to date. As many as 71 epiphytic medicinal plants were studied for their biological activities, showing promising pharmacological activities, including as anti-inflammatory, antimicrobial, and anticancer agents. There are several species that were not investigated for their activities and are worthy of exploration. These epipythes have the potential to furnish drug lead compounds, especially for treating cancers, and thus warrant indepth investigations.

Abstract
BACKGROUND We previously showed that 3-O-β-D-glucopyranosyl-(3R)-hydroxybutanolide (kinsenoside), a major compound of Anoectochilus formosanus, increased lipolysis through an AMP-activated protein kinase (AMPK)-dependent pathway. PURPOSE To extend our previous finding, we investigated the in vivo and in vitro effects of kinsenoside on lipolysis and the involvement of cyclic AMP (cAMP)-dependent protein kinase A (PKA) and AMPK in kinsenoside-mediated lipolysis. STUDY DESIGN/METHODS Mice were fed a high-fat diet for six weeks to induce lipid deposition and then treated with 50 and 100 mg/kg kinsenoside for two weeks. The coordination of PKA and AMPK activation in lipolysis in C3H10T1/2 adipocytes was evaluated in vitro by using PKA and AMPK's corresponding inhibitors, oil-red O staining, a glycerol production assay, and Western blot analysis. RESULTS Kinsenoside reduced body weight, fat pad mass, and hepatic lipid accumulation in obese mice, and concurrently increased the induction and activation of hormone-sensitive lipase (HSL), perilipin, adipose triglyceride lipase (ATGL), and carnitine palmitoyltransferase I (CPT1). Kinsenoside concentration-dependently increased PKA activation by increasing the phosphorylation of Ser/Thr-PKA substrates in vitro. These increases were accompanied by a reduction in fat accumulation. Using H89 and Rp-8-Br-cAMPs to inhibit PKA reduced the release of glycerol but did not alter the activation of peroxisome proliferator-activated receptor alpha or the expression of CPT1 or ATGL. By contrast, compound C, an AMPK inhibitor, inhibited CPT1 and ATGL expression in kinsenoside-treated C3H10T1/2 adipocytes. In addition, H89 caused the reactivation of AMPK downstream targets by increasing the levels of the active form of pAMPK-Thr172, suggesting that PKA negatively modulates AMPK activity. CONCLUSION Kinsenoside increased HSL activation through PKA-mediated phosphorylation at Ser660/563 and concomitantly increased perilipin activation in lipolysis. These lipolytic effects of kinsenoside were validated using 6-Bnz-cAMPs, a PKA agonist. In this study, we demonstrated that in addition to AMPK, PKA also plays a crucial role in kinsenoside-mediated lipolysis.

Abstract
The pathological superoxidative condition that retinal pigment epithelium (RPE) cells experience contributed to the advancement of age-related macular degeneration (AMD), which was accompanied by significant neovascularization. Therefore, the discovery of novel pharmacological candidates to ameliorate oxidative damage (H2O2) against RPE cells and inhibit the following angiogenesis simultaneously is urgently needed. Herein, we found that kinsenoside (Kin), an active component derived from Anoectochilus roxburghii, was able to protect RPE cells effectively and attenuate subsequent angiogenesis. In this study, H2O2-induced oxidative injury reduced RPE cell viability and increased cell apoptosis, which was significantly rescued by the treatment with Kin. Compared with H2O2 alone, Kin decreased the levels of Bax and increased the production of Bcl-2 in RPE cells. H2O2-stimulated VEGF up-regulation was inhibited by Kin treatment. Human umbilical vein endothelial cell (HUVEC) neovascularization induced by conditioned medium (CM) from H2O2-stimulated RPE cells was attenuated by treatment with Kin, VEGF antagonist, NF-κB, Erk-MAPK, and p38-MAPK inhibitors. Additionally, H2O2-activated phosphorylated expression of IκBα, p65, Erk, and p38 in RPE cells was inhibited by treatment with Kin. Taken together, Kin protected RPE from apoptosis against oxidative stress while simultaneously decreasing apoptosis-related neovascularization. This could be ascribed to the inhibition of Erk/p38/NF-κB signaling by Kin that contributed to the resulting decreased VEGF expression in H2O2-treated RPE cells.

ETHNOPHARMACOLOGICAL RELEVANCE Anoectochilus roxburghii (Orchidaceae), also known as Jinxianlian (Simplified Chinese: ) and Jinxianlan (Simplified Chinese: ), is valued in many Asian countries, where this plant species is used for medicinal, culinary, and ornamental purposes. As a food, A. roxburghii is widely used as a treatment booster and medicine because of its various beneficial properties; these include, most notably, the curative effects of heat dissipation and cooling of blood, elimination of dampness, detoxification, and immunity enhancement. AIM OF THIS REVIEW This review aims to provide up-to-date information on the phytochemistry, pharmacology, and clinical applications of A. roxburghii. MATERIALS AND METHODS Relevant information on A. roxburghii was obtained by an online search of worldwide-accepted scientific databases (Web of Science, ScienceDirect, Elsevier, Springer, NCBI, ACS Publications, CNKI, and Wanfang data). RESULTS Phytochemical investigations have revealed that the major chemical constituents of A. roxburghii are polysaccharides, flavonoids, glycosides, organic acids, volatile compounds, steroids, triterpenes, alkaloids, and nucleosides. These compounds have been proven to be the main bioactive substances responsible for pharmacological activities such as antidiabetic, antilipemic, anti-inflammatory, antiviral, liver protective, renal protective, immunomodulatory, abirritant, sedative, and antineoplastic effects. CONCLUSIONS A variety of dosage forms of A. roxburghii are currently being applied to patients suffering from hyperuricemia, type 2 diabetes mellitus, chronic hepatitis B, Helicobacter pylori infection, cough-variant asthma, and other conditions. Nevertheless, further research is needed to clarify A. roxburghii absorption, distribution, metabolic, and excretion pathways. Moreover, the toxicology in A. roxburghii and A. formosanus are also in urgent need of research, especially long-term in vivo chronic toxicity tests need to be carried out.

Abstract
UNLABELLED The central purpose of this study was to investigate therapeutic effects of the botanical derivative, kinsenoside (KD), in experimental autoimmune hepatitis (AIH). Treatment with KD substantially reduced hepatic histopathological damage, induced by lymphocyte infiltration and proinflammatory cytokines, in concanavalin A-induced T-cell-mediated hepatitis, and in dendritic cells (DCs) loaded with hepatocellular carcinoma cells (DC/Hepa1-6) induced murine AIH. Interactions between immune cells after KD treatment in AIH were detected by anti-CD8 antibody blocking, CD8+ T cell sorting, and vaccinated mice with KD-pretreated DCs in a DC/Hepa1-6 model. These results showed that KD inhibited the elevated expressions of CD86 and major histocompatibility complex II, densities of chemokine receptor C-C chemokine receptor type 7, and extensive migration to lymph nodes, and increased the programmed death ligand 1 level of DCs, followed by suppressing CD8+ T cells, characterized as low differentiation and cytotoxicity, and eliciting cytokines balance. Furthermore, biochemical analysis, two-dimensional fingerprint screen and three-dimensional molecular docking results showed that KD bound to the vascular endothelial growth factor receptor 2 (VEGFR2) kinase domain, which inhibited the metabolism-related phosphatidylinositol 3 kinase/protein kinase B (PI3K-AKT) pathway in DCs and DC-modulated CD8+ T cells to lower the mitochondrial membrane potential and glucose/lipid utilization ratio in both cells. KD reversed activation of the PI3K-AKT pathway by 740 Y-P (PI3K agonist), thereby impeding the translocation and dimerization of signal transducer and activators of transcription (STAT) 3 and synergistically blocking the inflammation-related Janus kinase (JAK) 2/STAT3 pathway in DCs and DC-modulated T cells. CONCLUSION KD treatment elicits immunosuppression against autoimmune liver injury by targeting VEGFR2, followed by diminishing the cross-talk of metabolism-related PI3K-AKT and inflammation-related JAK2-STAT3 pathways, and thereby disrupts DC-induced cross-priming of CD8+ T cell responses.

Abstract
Gouty arthritis is a rheumatic disease that is characterized by the deposition of monosodium urate (MSU) in synovial joints cause by the increased serum hyperuricemia. This study used a three-dimensional (3D) flowing microfluidic chip to screen the effective candidate against MSU-stimulated human umbilical vein endothelial cell (HUVEC) damage, and found kinsenoside (Kin) to be the leading active component of Anoectochilus roxburghi, one of the Chinese medicinal plant widely used in the treatment of gouty arthritis clinically. Cell viability and apoptosis of HUVECs were evaluated, indicating that direct Kin stimulation and conditioned medium (CM) from Kin-treated macrophages both negatively modulated with MSU crystals. Additionally, Kin was capable of attenuating MSU-induced activation of nuclear factor-κB/mitogen-activated protein kinase (NF-κB/MAPK) signaling, targeting IκB kinase-α (IKKα) and IKKβ kinases of macrophages and influencing the expressions of NF-κB downstream cytokines and subsequent HUVEC bioactivity. Inflammasome NLR pyrin domain-containing 3 (NALP3) and toll-like receptor 2 (TLR2) were also inhibited after Kin treatment. Also, Kin downregulated CD14-mediated MSU crystals uptake in macrophages. In vivo study with MSU-injected ankle joints further revealed the significant suppression of inflammatory infiltration and endothelia impairment coupled with alleviation of ankle swelling and nociceptive response via Kin treatments. Taken together, these data implicated that Kin was the most effective candidate from Anoectochilus roxburghi to treat gouty arthritis clinically.

Abstract
This study investigated biological activities including antioxidative stress, anti‐inflammation, and anti‐insulin resistance of Anoectochilus burmannicus aqueous extract (ABE). The results showed abilities of ABE to scavenging DPPH and ABTS free radicals in a dose‐dependent manner. Besides, ABE significantly reduced nitric oxide (NO) production in the lipopolysaccharide (LPS)‐treated RAW 264.7 via inhibition of mRNA and protein expressions of nitric oxide synthase (iNOS). The LPS‐induced mRNA expressions of cyclooxygenase‐2 (COX‐2) and interleukin 1β (IL‐1β) were suppressed by ABE. Moreover, ABE exerted anti‐insulin resistance activity as it significantly improved the glucose uptake in tumor necrosis factor (TNF)‐α treated 3T3‐L1 adipocytes. In addition, ABE at the concentration of up to 200 μg/mL was not toxic to human peripheral blood mononuclear cells (PBMCs) and did not induce mutations. Finally, the results of our study suggest the potential use of A. burmannicus as anti‐inflammatory, anti‐insulin resistance agents, or food supplement for prevention of chronic diseases.

Abstract
Kinsenoside, the herb-derived medicine isolated from the plant Anoect chilus, has diverse pharmacological actions, and it is considered to be a promising antihyperlipidemic drug candidate. This study evaluates the effects of kinsenoside on CYP enzyme-mediated drug metabolism in order to predict the potential for kinsenoside-drug interactions. Kinsenoside was tested at different concentrations of 0.1, 0.3, 1, 3, 10, 30, and 100 µM in human liver microsomes. The c Cktail probe assay based on liquid chromatography-tandem mass spectrometry was conducted to measure the CYP inhibitory effect of kinsenoside. Subsequently, the metabolism profiles of amlodipine and lovastatin in human liver microsomes were analyzed following co-incubation with kinsenoside. The concentration levels of the parent drug and the major metabolites were compared with the kinsenoside-cotreated samples. The effect of kinsenoside was negligible on the enzyme activity of all the CYP isozymes tested even though CYP2A6 was slightly inhibited at higher concentrations. The drug-drug interaction assay also showed that the concomitant use of kinsenoside has a non-significant effect on the concentration of lovastatin or amlodipine, and their major metabolites. So, it was concluded that there is almost no risk of drug interaction between kinsenoside and CYP drug substrates via CYP inhibition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anoectochilus roxburghii (Wall.) Lindl. 1832 is an herbal medicine used to treat diabetes in China. Considering that Anoectochilus roxburghii polysaccharose (ARP) is the main constituent of Anoectochilus roxburghii, the present study is aimed to investigate the renal protection of ARP and its possible mechanism in diabetic mice. MATERIALS AND METHODS Institute of Cancer Research (ICR) mice were induced to diabetes with high-fat diet (HFD) and low-dose streptozotocin (STZ). ARP (100, 300 mg/kg) was orally administrated to diabetic mice once a day for consecutive 15 days. The fasting glucose level, expressions of key proteins of p38 MAP kinase cascade, inflammatory factors, fibronectin (FN) and the activities of matrix metalloproteinases (MMPs) were measured. Furthermore, the histological examination of the separated kidneys was also carried out. RESULTS Compared with the diabetic mice, ARP administration induced a significant decrease in blood glucose level and improved the body weight of diabetic mice. In addition, ARP inhibited the expression of renal p38 MAP kinase cascade and its downstream inflammatory factors including tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1), FN as well as MMP2/9. Moreover, the histological examination showed an apparent reduction of mesangial matrix deposition and damage of microvascular structure after ARP administration. CONCLUSIONS The protective effects of ARP on diabetic renal damage may be attributed to the inhibition of p38 MAP kinase cascade and then attenuating the inflammatory responses and high glucose-induced renal damage.

Abstract
Intact Crocus sativus petals were studied for the first time by high-resolution magic angle spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy, revealing the presence of kinsenoside (2) and goodyeroside A (3), together with 3-hydroxy-γ-butyrolactone (4). These findings were confirmed by HR-NMR analysis of the ethanol extract of fresh petals and showed that, even though carried out rapidly, partial hydrolysis of glucopyranosyloxybutanolides occurs during extraction. On the other hand, kaempferol 3-O-sophoroside (1), which is "NMR-silent" in intact petals, is present in extracts. These results suggest to evaluate the utilization of saffron petals for phytopharmaceutical and nutraceutical purposes to exploit a waste product of massive production of commercial saffron and point to the application of HR-MAS NMR for monitoring bioactive compounds directly on intact petals, avoiding the extraction procedure and the consequent hydrolysis reaction.

Abstract
BACKGROUND Currently, more than one-third of the global population is overweight or obese, which is a risk factor for major causes of death including cardiovascular disease, numerous cancers, and diabetes. Kinsenoside, a major active component of Anoectochilus formosanus exhibits antihyperglycemic, antihyperliposis, and hepatoprotective effects and can be used to prevent and manage obesity. PURPOSE This study examined the catabolic effects of kinsenoside on lipolysis in adipocytes transformed from C3H10T1/2 cells. STUDY DESIGN/METHODS The lipolytic effect of kinsenoside in C3H10T1/2 adipocytes was evaluated by oil-red O staining and glycerol production. The underlying mechanisms were assessed by Western blots, chromatin immunoprecipitation (IP), Co-IP, EMSA and siRNAs verification. RESULTS We demonstrated that kinsenoside increased both adipose triglyceride lipase (ATGL)-mediated lipolysis, which was upregulated by AMP-activated protein kinase (AMPK) activation, and the hydrolysis of triglycerides to glycerol and fatty acids that require transportation into mitochondria for further β-oxidation. We also demonstrated that kinsenoside increased the phosphorylation of peroxisome proliferator-activated receptor alpha (PPARα) and CRE-binding protein (CREB), and the protein levels of silent information regulator T1 (SIRT1), peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) and carnitine palmitoyltransferase I (CPT1) through an AMPK-dependent mechanism. SIRT1 deacetylated PGC-1α, facilitating AMPK-mediated PGC-1α phosphorylation and increasing the interaction of PPARα with its coactivator, PGC-1α. This interaction elevated the expression of CPT1, a shuttle for the mitochondrial transport of fatty acids, in kinsenoside-treated cells. In addition, AMPK-phosphorylation-mediated CREB activation caused kinsenoside-mediated PGC-1α upregulation. CONCLUSION AMPK activation not only elevated ATGL expression for lipolysis but also induced CPT1 expression for further mitochondrial translocation of fatty acids. The results suggested that the mechanism underlying the catabolic effects of kinsenoside on lipolysis and increased CPT1 induction was mediated through an AMPK-dependent pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anoectochilus roxburghii is a traditional Chinese herb used for treatment of diabetes and some other diseases. Anoectochilus roxburghii polysaccharose (ARP) is the main constituent of Anoectochilus roxburghii. The present study aimed to investigate the antidiabetic effects of ARP in diabetic mice induced by high-fat diet and streptozotocin. MATERIALS AND METHODS Two doses of ARP (100 or 300 mg/kg) were administered once daily for 25 days to diabetic mice. To evaluate the antidiabetic effects of ARP, the fasting glucose levels, aspartate aminotransferase (AST), alanine transaminase (ALT) and superoxide dismutase (SOD) activities, malondialdehyde (MDA) content, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and liver glycogen were examined. Furthermore, histological examinations were carried out on the separated pancreas and liver of mice. RESULTS Compared with untreated diabetic mice, ARP (100 or 300 mg/kg) caused a significant decrease in blood glucose levels, activities of AST and ALT, and MDA contents, and a significant increase in liver glycogen contents, SOD activities, thymus index and spleen index. Simultaneously, the alteration in lipid metabolism was partially attenuated as evidenced by decreased serum TC, TG and LDL-C concentrations in diabetic mice. In addition, histological examinations showed that administration of ARP (100 or 300 mg/kg) significantly attenuated the pathologic lesions in pancreas and liver of diabetic mice, and improved pancreas and liver function. CONCLUSIONS The antidiabetic activity of ARP may be attributed to the improvement of glucose and lipid metabolism, increase of immune protection and reduction of oxidative stress.

Kinsenoside (1) and goodyeroside A (2), two naturally occurring stereoisomers with diverse biological activities, have been synthesized efficiently by a chemo-enzymatic approach with a total yield of 12.7%. The aglycones, (R)- and (S)-3-hydroxy-γ-butyrolactone, were prepared from d- and l-malic acid by a four-step chemical approach with a yield of 75%, respectively. These butyrolactones were then successfully glycosidated using β-d-glucosidase as a catalyst in a homogeneous organic-water system. Under the optimized enzymatic conditions, the yields of kinsenoside and goodyeroside A in the enzymatic steps both reached 16.8%.

Abstract
Anoectochilus formosanus, commonly known as "Jewel Orchid", is a Chinese folk medicine used to treat hypertension, diabetes, and heart disease. The existence of A. formosanus is currently threatened by habitat loss, human and animal consumption, etc. The highly potent medicinal activity of A. formosanus is due to its secondary metabolites, especially kinsenosides and flavonoids. This orchid also has a unique mycorrhizal relationship. Most adult orchids rely on endophytes for mineral nutrition and have complex interactions with them, which are related to plant growth, yield and changes in secondary metabolites. This study investigated the promoting role of F-23 fungus (genus Mycena) on the biomass and contents of kinsenosides and flavonoids of A. formosanus in pot culture. The following were observed after 10 weeks of symbiotic cultivation: increased shoot height, shoot dry weight, and leaf numbers by 16.6%, 31.3%, and 22.5%, respectively; increased contents of kinsenosides, isorhamnetin-3-O-β-D-rutinoside, and isorhamnetin-3-O-β-D-glucopyranoside by 85.5%, 226.1%, and 196.0%, respectively; some hyphae in epidermal cells dyed red and/or reddish brown by safranine; and, significantly reduced number of starch grains in cortical cells. Moreover, F-23 fungus significantly improved the kinsenoside and flavonoid contents of A. formosanus. These findings supported the reports that endophytes can alter the production of secondary metabolites in their plant hosts, although further physiological, genetic and ecological analyses are warranted.

Abstract
AIM In the present study, we have evaluated the hepatoprotective ability of kinsenoside, a major component of Anoectochilus formosanus, in vitro and in vivo. MATERIALS AND METHODS The inhibitory action of kinsenoside on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells and Kupffer cells were investigated. Mice hepatic injury was produced by CCl(4) twice a week for 3 weeks. Mice in the three CCl(4) group were treated daily with water and kinsenoside throughout the experimental period. RESULTS In LPS-stimulated macrophage RAW 264.7 cells and Kupffer cells, kinsenoside inhibited nitric oxide (NO) production and also blocked LPS-induced inducible NO synthase expression. Furthermore, kinsenoside inhibited the NF-κB activation induced by LPS, and this is associated with the abrogation of IκBα degradation, with subsequent decreases in nuclear p65 and p50 protein levels. Moreover, the phosphorylations of p38, ERK and JNK in LPS-stimulated RAW 264.7 cells were suppressed by kinsenoside. In the in vivo study, kinsenoside significantly protected the liver from injury, by reducing the activities of plasma aminotransferase, and by improving the histological architecture of the liver. kinsenoside inhibited Kupffer cell activation by reducing the CD 14 mRNA and protein expressions. CONCLUSION These results indicate that kinsenoside alleviates CCl(4)-induced liver injury, and this protection is probably due to the suppression of Kupffer cell activation.

Abstract
Absorption enhancers are substances used for temporarily increasing a membrane's permeability (e.g., the skin and mucosa), either by interacting with its components (lipids or proteins) or by increasing the membrane/vehicle partition coefficient. This article presents the results of biophysical and permeability studies performed with Laurocapram and its analogues. As shown, Laurocapram and its analogues present different enhancing efficacies, for most of both hydrophilic and lipophilic substances. The enhancing effect of Laurocapram (Azone) is attributed to different mechanisms, such as insertion of its dodecyl group into the intercellular lipidic bilayer, increase of the motion of the alkylic chains of lipids, and fluidization of the hydrophobic regions of the lamellate structure. Toxicological studies reveal a low toxicity for Laurocapram, and for some derivatives, a relationship exists between toxicity and the number of carbons in the alkylic chain. Very important, when applied to human skin, Laurocapram shows a minimal absorption, being quickly eliminated from circulation. However, although Laurocapram and its derivatives have been shown to provide enhancement, they have not been widely accepted because of their suspected pharmacological activity or questions about their safety.

Abstract
The purpose of this study was to investigate the hepatoprotective effects of Anoectochilus formosanus effective fraction (AFEF) on chronic liver damage induced by carbon tetrachloride (CCl4) in mice. CCl4 (5%; 0.1 mL/10 g body weight) was given twice a week for 9 weeks, and mice received AFEF throughout the whole experimental period. Plasma GPT, hepatic levels of hydroxyproline and malondialdehyde were significantly lower in mice treated with AFEF compared with those treated with CCl4 only. Liver pathology in the AFEF-treated mice was also improved. RT-PCR analysis showed that AFEF treatment increased the expression of methionine adenosyltransferase 1A and decreased the expression of collagen(alpha1)(I) and transforming growth factor-beta1. These results clearly demonstrated that AFEF reduced the hepatic damage induced by CCl4 in mice.

Abstract
Oleanolic acid (OA) and ursolic acid (UA) are the two important bioactive compounds in Anoectochilus roxburghii (wall) Lindl (A. roxburghii), which has been used as a traditional Chinese medicine. So far, there has been no report to indicate that A. roxburghii contains these two bioactive compounds. It is necessary to develop an effective method to extract and analyze OA and UA in A. roxburghii. In this paper, a quantitative method, consisting of supercritical fluid extraction (SFE) followed by liquid chromatography-atmospheric pressure chemical ionization-ion trap mass spectrometry (LC-APCI-IT-MS) analysis, was developed for identification of OA and UA in A. roxburghii. The extraction was carried out by using CO(2) as the supercritical fluid and ethanol as the modifier before LC separation. The mobile phase used for LC separation consisted of acetic acid (1%, v/v), water (15%, v/v) and methanol (84%, v/v), and the elution was performed at a flow rate of 0.8 ml/min. The mass spectrometer was operated in APCI(+) mode with selected ion monitoring (SIM) to quantify OA and UA at m/z 439.4. Under optimum conditions, the linear responses of OA and UA were obtained in the concentration range of 0.5-80 (r = 0.9992) and 0.5-50 microg/ml (r = 0.9989) with the detection limits of 0.125 and 0.085 microg/ml, respectively. The proposed method has been used for the identification and quantitation of OA and UA in a real A. roxburghii sample.

Abstract
A clinical study was performed on the effect of in vitro cultured Anoectochilus formosanus HAYATA on lipid-metabolism. Sixty-six volunteers, including 36 healthy, 14 high-triglyceride-, 11 high-cholesterol- and 5 high-triglyceride- and high cholesterol- subjects, were administrated with A. formosanus (450 mg/day) for 6 months or 12 months. A. formosanus significantly decreased the concentrations of the serum levels of cholesterol, low density lipoprotein and very low density lipoprotein in all volunteers. The results of the present study suggested that A. formosanus might function as a liver activator resulting in improvement of lipid-metabolism.

Abstract
beta-Sitosterol and stigmasterol are the most common phytosterols in traditional Chinese medicine. They have been proved to have many important bioactivities. To the best of our knowledge, this is the first report that beta-sitosterol, stigmasterol and ergosterol coexisting in A. roxburghii herbs can be simultaneously extracted by a supercritical fluid extraction (SFE) procedure; then a simple high-performance liquid chromatography/atmospheric pressure chemical ionization ion trap mass spectrometry (HPLC/APCI/MS) method was developed for simultaneous identification and determination of these three compounds. The ion trap MS/MS detector was equipped with an atmospheric pressure chemical ionization source operating in the positive ion mode, APCI(+). The linear responses were obtained in the concentration range of 0.50-150 microg/mL (r = 0.9999) for ergosterol, 5-400 microg/mL (r = 0.9999) for stigmasterol, and 10-2000 microg/mL (r = 0.9998) for beta-sitosterol. An orthogonal L(9) (3(3)) test design was employed for optimization of the SFE process. Under the optimized conditions, i.e. pressure of 25 mPa, temperature of 45 degrees C and ethanol as modifier, the concentrations of sterols in the extract were found to be 2.89% (g/g) for beta-sitosterol, 3.56% (g/g) for stigmasterol and 2.96% (g/g) for ergosterin. The SFE method was also compared with a previously developed Soxhlet extraction. The SFE method produced higher yields of sterols than that of the Soxhlet extraction. The proposed method has been successfully used for identification and quantitation of beta-sitosterol, stigmasterol and ergosterin in a real A. roxburghii sample.

Abstract
The aim of this study was to investigate the effects of aqueous extract of Anoectochilus formosanus (AFE) on liver fibrogenesis in carbon tetrachloride (CCl4)-induced cirrhosis. Fibrosis was induced in rats by oral administration of CCl4 (20%, 0.5 ml/rat, p.o.) twice a week for 8 weeks. AFE (0.5 and 2.0 g/kg, p.o., daily for 8 weeks) was administered to rats simultaneously. AFE showed reducing actions on the elevated levels of GOT and GPT caused by CCl4. Liver fibrosis in rats induced by CCl4 led to the drop of serum albumin concentration; the AFE increased the albumin concentration. The CCl4-induced liver fibrosis markedly caused liver atrophy and splenomegalia, while AFE increased the liver weight, and decreased the spleen weight. The CCl4-induced liver fibrosis decreased the protein content, and increased collagen contents in rat's liver. AFE significantly increased the contents of protein and reduced the amount of collagen in the liver. In CCl4-treated rats, glutathione concentrations of liver were not affected. AFE significantly increased liver glutathione concentrations. All these results clearly demonstrate that AFE can reduce the liver fibrogensis in rats induced by CCl4.

Abstract
1. The present study examined the effects of an aqueous extract of Anoectochilus formosanus (AFE) on both hepatic fibrosis and regeneration in rats. 2. Fibrosis was induced by intraperitoneal injection of dimethylnitrosamine (DMN) for 3 consecutive days per week for 4 weeks. 3. In DMN-treated rats, liver cirrhosis-associated complications, such as liver atrophy, low concentrations of serum albumin and the accumulation of hepatic collagen, were observed. The AFE protected the liver against DMN-induced fibrosis, as determined by morphological and biochemical observations. 4. In addition, AFE was administered to two-thirds hepatectomized normal and DMN-injured rats. Three and 5 days after hepatectomy, AFE increased the extent of liver weight regeneration and the number of S-phase cells in DMN-injured rats, but not in normal rats. 5. These results show that AFE seems to be useful in the repair of liver injury, improvement of fibrotic changes and promotion of liver regeneration.
