Abstract
Gromwell (Lithospermum erythrorhizon, LE) can mitigate obesity-induced skeletal muscle atrophy in C2C12 myotubes and high-fat diet (HFD)-induced obese mice. The purpose of this study was to investigate the anti-skeletal muscle atrophy effects of LE and the underlying molecular mechanism. C2C12 myotubes were pretreated with LE or shikonin, and active component of LE, for 24 h and then treated with 500 μM palmitic acid (PA) for an additional 24 h. Additionally, mice were fed a HFD for 8 weeks to induced obesity, and then fed either the same diet or a version containing 0.25% LE for 10 weeks. LE attenuated PA-induced myotubes atrophy in differentiated C2C12 myotubes. The supplementation of LE to obese mice significantly increased skeletal muscle weight, lean body mass, muscle strength, and exercise performance compared with those in the HFD group. LE supplementation not only suppressed obesity-induced skeletal muscle lipid accumulation, but also downregulated TNF-α and atrophic genes. LE increased protein synthesis in the skeletal muscle via the mTOR pathway. We observed LE induced increase of mitochondrial biogenesis and upregulation of oxidative phosphorylation related genes in the skeletal muscles. Furthermore, LE increased the expression of peroxisome proliferator-activated receptor-gamma coactivator-1 alpha and the phosphorylation of adenosine monophosphate-activated protein kinase. Collectively, LE may be useful in ameliorating the detrimental effects of obesity-induced skeletal muscle atrophy through the increase of protein synthesis and mitochondrial biogenesis of skeletal muscle.

Abstract
In recent years, the utilization of smart colorimetric packaging films for monitoring food freshness has garnered significant concentration. However, their limited tensile strength, hydrophobicity, antioxidant, and antibacterial properties have been substantial barriers to widespread adoption. In this study, we harnessed the potential of biodegradable materials, specifically chitosan/polyvinyl alcohol, alongside shikonin extracted from Radix Lithospermi and ZnO nanoparticles, to create a novel colorimetric sensing film. This film boasts an impressive tensile strength of 82.36 ± 2.13 MPa, enhanced hydrophobic characteristics (exemplified by a final contact angle of 99.81°), and outstanding antioxidant and antibacterial properties. It is designed for real-time monitoring of shrimp freshness. Additionally, we verified the effectiveness of this sensing film in detecting shrimp freshness across varying temperature conditions, namely 25 °C and 4 °C was validated through the measurement of total volatile basic nitrogen (TVB-N). Visual inspection unequivocally revealed a transition in color from dark red to purple-light blue and finally to dark bluish providing a clear indication of shrimp spoilage, which demonstrated a strong correlation with the TVB-N content in shrimp measured through standard laboratory procedures. The colorimetric sensing film developed in this study holds great promise for creating smart labels with exceptional antioxidant and antibacterial properties, tailored for visual freshness monitoring of shrimp.

Abstract
Shikonin is extracted from the roots of Lithospermum erythrorhizon, and shikonin extracts have been shown to have inhibitory effects on several bacteria. However, shikonin extracts are difficult to formulate because of their poor water solubility. In the present study, we prepared a shikonin dispersion, which was solubilized by the inclusion of β-1,3-1,6 glucan, and analysed the inhibitory effects of this dispersion on Streptococcus mutans and non-mutans streptococci. The shikonin dispersion showed pronounced anti-S. mutans activity, and inhibited growth of and biofilm formation by this bacterium. The shikonin dispersion also showed antimicrobial and antiproliferative effects against non-mutans streptococci. In addition, a clinical trial was conducted in which 20 subjects were asked to brush their teeth for 1 week using either shikonin dispersion-containing or non-containing toothpaste, respectively. The shikonin-containing toothpaste decreased the number of S. mutans in the oral cavity, while no such effect was observed after the use of the shikonin-free toothpaste. These results suggest that shikonin dispersion has an inhibitory effect on S. mutans and non-mutans streptococci, and toothpaste containing shikonin dispersion may be effective in preventing dental caries.

Abstract
BACKGROUND Uveitis is an inflammatory eye condition that threatens vision, and effective anti-inflammatory treatments with minimal side effects are necessary to treat uveitis. PURPOSE This study aimed to investigate the effects of Lithospermum erythrorhizon Siebold & Zucc. against endotoxin-induced uveitis in rat and mouse models. METHODS Endotoxin-induced uveitis models of rats and mice were used to evaluate the effects of l. erythrorhizon treatment. Clinical inflammation scores and retinal thickness were assessed in the extract of l. erythrorhizon-treated rats. Histopathological examination revealed inflammatory cell infiltration into the ciliary body. Protein concentration, cellular infiltration, and prostaglandin-E2 levels were measured in the aqueous humor of the extract of l. erythrorhizon-treated rats. Protective effects of l. erythrorhizon on the anterior segment of the eye were examined in mice with endotoxin-induced uveitis. Additionally, we investigated the effect of l. erythrorhizon on the expression of pro-inflammatory cytokines [tumor necrosis factor alpha, interleukin-6, and interleukin-8] in lipopolysaccharide-stimulated THP1 human macrophages and examined the involvement of nuclear factor kappaB/activator protein 1 and interferon regulatory factor signaling pathways. Furthermore, three components of l. erythrorhizon were identified and assessed for their inhibitory effects on LPS-induced inflammation in RAW264.7 macrophage cells. RESULTS Treatment of the extract of l. erythrorhizon significantly reduced clinical inflammation scores and retinal thickening in rats with endotoxin-induced uveitis. Histopathological examination revealed decreased inflammatory cell infiltration into the ciliary body. The extract of l. erythrorhizon effectively reduced the protein concentration, cellular infiltration, and PG-E2 levels in the aqueous humor of rats with endotoxin-induced uveitis. In mice with endotoxin-induced uveitis, the extract of l. erythrorhizon demonstrated a protective effect on the anterior segment of the eye by reducing inflammation and retinal thickening. The extract of l. erythrorhizon suppressed the expression of pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin-6, and interleukin-8) in lipopolysaccharide-induced inflammation in THP1 human macrophages, by modulating nuclear factor kappaB/activator protein 1 and interferon regulatory factor signaling pathways. Moreover, shikonin, acetylshikonin, and β, β-dimethylacryloylshikonin showed dose-dependent inhibition of nitric oxide, tumor necrosis factor alpha and interleukin-6 production in RAW264.7 macrophage cells. CONCLUSION The extract of l. erythrorhizon is a potential therapeutic agent for uveitis management. Administration of the extract of l. erythrorhizon led to reduced inflammation, retinal thickening, and inflammatory cell infiltration in rat and mouse models of uveitis. The compounds (shikonin, acetylshikonin, and β, β-dimethylacryloylshikonin) identified in this study played crucial roles in mediating the anti-inflammatory effects of l. erythrorhizon. These findings indicate that the extract of l. erythrorhizon and its constituent compounds are promising candidates for further research and development of novel treatment modalities for uveitis.

Abstract
The common gromwell Lithospermum officinale L. is a valuable medicinal plant that has been used in traditional medicine since ancient times. A method to quantify flavonoids in L. officinale leaves by differential spectrophotometry was developed taking advantage of the flavonoid reaction with aluminum chloride. The optimum duration of the reaction was determined, as well as the optimum volume-to-volume ratio between an aqueous ethanolic extract of L. officinale leaves and 2% aluminum chloride (aqueous ethanolic solution). Rutin was used as a standard. The method was validated in terms of specificity, linearity, precision, and accuracy and proved suitable for analytical purposes. The flavonoid content expressed in terms of rutin was found to exceed 2% of the absolutely dry weight in L. officinale leaves over different years of cultivation.

Abstract
OBJECTIVE To investigate the optimal dose of mifepristone and lithospermum combination regimen on medical abortion in early pregnancy rats without increasing side effects. STUDY DESIGN Sixty sexually mature female Sprague Dawley (SD) rats with early pregnancy were randomly allocated into 10 groups, including a control group (treated with 0.5% CMC-Na) and nine experiments (treated with 1 mg/kg mifepristone, and 90, 180, 270, and 540 mg/kg lithospermum, and 90/180/270/540 mg/kg lithospermum +1 mg/kg mifepristone, respectively). The hormone levels, factors associated with endometrial bleeding, oxidative stress, and apoptotic proteins in the endometrium, were then investigated. RESULTS The results demonstrated that 540 mg/kg lithospermum plus 1 mg/kg mifepristone treatment significantly improved the abortion rate when compared with the control group. Compared with the 1 mg/kg mifepristone, 540 mg/kg lithospermum plus 1 mg/kg mifepristone treatment did not induce significant increase in factors associated with abnormal endometrial bleeding, such as matrix metalloproteinase-9 (MMP9). However, mifepristone and lithospermum combination regimen promoted the expression level of malondialdehyde (MDA), activated caspase 3, caspase 9 and Bax, meanwhile, reduced the expression of superoxide dismutase (SOD) and Bcl-2. CONCLUSION These findings provided strong evidence that mifepristone and lithospermum combination regimen can obtain satisfactory abortion effect without increasing the expression level of bleeding-related factors.

Abstract
The potential of plant extracts as bioinsecticides has been described as a promising field of agricultural development. In this work, the extracts of Punica granatum (pomegranate), Phytolacca americana (American pokeweed), Glandora prostrata (shrubby gromwell), Ulex europaeus (gorce), Tagetes patula (French marigold), Camellia japonica red (camellia), Ruta graveolens (rue or herb-of-grace) were obtained, purified, and their activity against Spodoptera frugiperda (Sf9) insect cells was investigated. From the pool of over twenty extracts obtained, comprising different polarities and vegetable materials, less polar samples were shown to be more toxic towards the insect cell line Sf9. Among these, a dichloromethane extract of R. graveolens was capable of causing a loss of viability of over 50%, exceeding the effect of the commercial insecticide chlorpyrifos. This extract elicited chromatin condensation and the fragmentation in treated cells. Nanoencapsulation assays of the cytotoxic plant extracts in soybean liposomes and chitosan nanostructures were carried out. The nanosystems exhibited sizes lower or around 200 nm, low polydispersity, and generally high encapsulation efficiencies. Release assays showed that chitosan nanoemulsions provide a fast and total extract release, while liposome-based systems are suitable for a more delayed release. These results represent a proof-of-concept for the future development of bioinsecticide nanoformulations based on the cytotoxic plant extracts.

Abstract
Shikonin is a natural naphthoquinone derivative that specifically occurs in boraginaceous plants, and the major active ingredient of the medicinal plant Lithospermum erythrorhizon. Previously, a cytochrome P450 oxygenase (CYP) CYP76B74 catalyzing 3″-hydroxylation of geranylhydroquinone (GHQ) - a key intermediate of shikonin biosynthesis, was identified from cultured cells of Arnebia euchroma. However, the enzymes catalyzing oxidation of the geranyl side-chain of GHQ from L. erythrorhizon remain unknown. In this study, we performed transcriptome analysis of different tissues (red roots and green leaves/stems) from L. erythrorhizon using RNA sequencing technology. Highly expressed CYP genes found in the roots were then heterologously expressed in Saccharomyces cerevisiae and functionally screened with GHQ as the substrate. As the result, two CYPs of CYP76B subfamily catalyzing the oxidation of GHQ were characterized. CYP76B100 catalyzed the hydroxylation of the geranyl side-chain of GHQ at the C-3″ position to form 3″-hydroxyl geranylhydroquinone (GHQ-3″-OH). The enzyme CYP76B101 carried out oxidation reaction of GHQ at the C-3″ position to produce a 3″-carboxylic acid derivative of GHQ (GHQ-3″-COOH) as well as GHQ-3″-OH. This enzyme-catalyzed oxidation reaction with GHQ as the substrate is reported for the first time. This study implicates CYP76B100 and CYP76B101 as having a potential role in shikonin biosynthesis in L. erythrorhizon.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lithospermum erythrorhizon (LE) and Angelica sinensis (AS), widely used in several folk medicine for wound, pus discharge and dermatitis for the history of several hundred years in Asian countries. AIM OF STUDY To investigate the therapeutic effect of LE and AS on Der p2-induced inflammatory response in human bronchial epithelial (BEAS-2B) cells. METHODS The effects of Der p2 stimulation on thymic stromal lymphopoietin (TSLP), the nuclear factor kappa B (NF-κB) pathway, the inflammasome (specifically, the apoptosis speck-like protein [ASC] and nod-like receptor 3 [NLRP3]), Caspase-1 and the signal transducer and activator of transcription (STAT) 3 pathway were evaluated in the human bronchial epithelial (BEAS-2B) cells. RESULTS The results indicated that LE, AS, and LE+AS reduced TSLP, I kappa B kinase-α, and NLRP3 levels; LE and AS reduced Caspase-1; LE and LE+AS also reduced NF-κB p50, NF-κB p65, ASC, and STAT3 levels. CONCLUSION Both LE and AS aqueous extracts exert anti-inflammatory effects in Der p2-stimulated BEAS-2B cells. These effects may involve multiple mechanisms, including the inhibition of TSLP production as well as the suppression of IKKα, Caspase-1 and NLRP3; however, additional studies are warranted to elucidate the underlying mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jawoongo is a traditional drug ointment (with a traditional botanic formula) used for the treatment of burns and wounds in Korea. One of the components of Jawoongo is Lithospermi Radix (LR, the dried root of Lithospermum erythrorhizon Siebold & Zucc., also known as Zicao or Gromwell), which contains deoxyshikonin and its derivatives. OBJECTIVE The aim of the present study was to investigate the effects of deoxyshikonin on wound healing. MATERIALS AND METHODS The effects of LR extract and deoxyshikonin on tube formation and migration were measured in human umbilical vein vascular endothelial cells (HUVEC) and HaCaT cells, respectively. We evaluated protein expression of mitogen-activated protein kinase (MAPK) activation by Western blotting. The wound healing effects of deoxyshikonin was assessed in a mouse model of cutaneous wounds. RESULTS The results showed that deoxyshikonin enhanced tube formation in HUVEC and migration in HaCaT cells. From the western blot analysis, we found that deoxyshikonin stimulated the phosphorylation of p38 and extracellular signal-regulated kinase (ERK) in HaCaT cells. Moreover, 20µm deoxyshikonin-treated groups showed accelerated wound closure compared with the controls in a mouse model of cutaneous wounds. CONCLUSION In conclusion, the current data indicate that deoxyshikonin treatment elevated tube formation in HUVECs, and that deoxyshikonin-induced proliferation and migration in HaCaT cells were mediated by the activation of ERK and p38 MAPKs, respectively. Collectively, these data suggest that deoxyshikonin in Jawoongo must be an active compound for may be wound healing.

Abstract
β,β-dimethylacryloyl alkannin (DMA) is a key component of Lithospermum and possesses good efficacy for treating psoriasis. DMA inhibits activated dendritic cells (DCs), but the mechanism is unknown. Therefore, this study aimed to explore the modulation of the TLR7/8 pathway by DMA in psoriasis-activated DCs. Models of psoriasis-like skin lesions were established using BALB/c mice; 8 mice were treated with DMA (2.5mg/kg). Bone marrow cells were isolated and induced into DCs using R848, a TLR7/8 agonist. Splenic CD11c+ cells were detected by flow cytometry. Skin CD11c+ cells were detected by immunofluorescence. TLR7, TLR8, MYD88, and IRAKM proteins were detected by Western blot. The effects of DMA on surface molecules of DCs were observed by flow cytometry. mRNA expression of inflammatory factors was detected by qRT-PCR. Secreted cytokines were detected by cytometric bead array. Compared with the model group, psoriasis-like skin lesions were alleviated by DMA, the splenic CD11c+ cells were significantly decreased (P<0.01), and CD11c+ cell numbers in skin lesions were decreased (P<0.01). Expression levels of TLR7, MYD88, and IRAKM were significantly decreased (P<0.05). R848-stimulated DCs showed increased expression of I-A/I-E, CD80, and CD86 (P<0.01), increased IL-23 and IL-1β mRNA and secretion (P<0.05), and increased TLR7, TLR8, MYD88, and IRAKM expression (P<0.01); DMA inhibited all of these effects of the TLR7/8 pathway activation by R848 (P<0.05). In conclusion, DMA could inhibit psoriasis-activated DCs via the TLR7/8 pathway.

Abstract
BACKGROUND Gromwell is known to have diverse pharmacological, cosmetic and nutritional benefits for humans. Nevertheless, the biological influence of gromwell extract (GE) on the general physiology of eukaryotic cells remains unknown. In this study a global transcriptome analysis was performed to identify genes affected by the addition of GE with Cryptococcus neoformans as the model system. RESULTS In response to GE treatment, genes involved in signal transduction were immediately regulated, and the evolutionarily conserved sets of genes involved in the core cellular functions, including DNA replication, RNA transcription/processing and protein translation/processing, were generally up-regulated. In contrast, a number of genes involved in carbohydrate metabolism and transport, inorganic ion transport and metabolism, post-translational modification/protein turnover/chaperone functions and signal transduction were down-regulated. Among the GE-responsive genes that are also evolutionarily conserved in the human genome, the expression patterns of YSA1, TPO2, CFO1 and PZF1 were confirmed by northern blot analysis. Based on the functional characterization of some GE-responsive genes, it was found that GE treatment may promote cellular tolerance against a variety of environmental stresses in eukaryotes. CONCLUSIONS GE treatment affects the expression levels of a significant portion of the Cryptococcus genome, implying that GE significantly affects the general physiology of eukaryotic cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lithospermum erythrorhizon has long been used in traditional Asian medicine for the treatment of diseases including skin cancer. In this study, hexane extract from the roots of Lithospermum erythrorhizon (LEH) was chemically characterized and its anticancer activity was tested against the most aggressive form of skin cancer. MATERIALS AND METHODS The in vitro anticancer studies viz. cell growth, cell cycle and apoptosis, and the expression of tumor regulating proteins were analyzed against B16F10 melanoma cells. In addition, C57BL/6 mice models were used to evaluate the in vivo anticancer potential of LEH. Mice were intraperitoneally injected with LEH at doses of 0.1 and 10mg/kg every 3 days. The tumor inhibition ratio was determined after 21 days of treatment and the histopathological analyses of the tumor tissues were compared. Further, LEH was purified and its active compounds were structurally elucidated and identified by NMR spectra and quantified by HPLC analyses. RESULTS LEH effectively inhibits the growth of melanoma cells with an IC(50) of 2.73μg/ml. Cell cycle analysis revealed that LEH increased the percentage of cells in sub-G1 phase by dose dependent manner. LEH exhibited down regulation of anti-apoptotic Bcl-2 family proteins and up regulation of apoptotic Bax protein expression. Importantly, LEH induced cleavage of poly (ADP-ribose) polymerase (PARP) and activated the caspase cascade (caspase 3) with this cleavage mediating the apoptosis of B16F10 cells. LEH treatment at a dose of 10mg/kg for 21 days in experimental mice implanted with tumors resulted in significant reduction of the tumor growth (43%) and weight (36%). Histopathology analysis of LEH treated tumor tissues showed evidence of increased necrotic cells in a concentration dependent manner. Meanwhile, five naphthoquinone compounds [Shikonin (1); Deoxyshikonin (2); β-Hydroxyisovalerylshikonin (3); Acetylshikonin (4) and Isobutyrylshikonin (5)] were purified from LEH and responsible for its anticancer activity. CONCLUSION LEH induced apoptosis in B16F10 cells by activation of caspase 3 and inducing sub-G1 cell cycle arrest. LEH exhibited both in vitro and in vivo anticancer activity. Shikonin derivatives in the LEH are responsible for the anticancer activity.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of lyophilized Salvia salt of lithospermic acid powder for injection (SSLA) in treating coronary heart diseases angina pectoris (CHD-AP) of Xin-blood stasis syndrome type, and to conduct the non-inferiority trial with Danshen injection (DSI) as positive control. METHODS An non-inferiority clinical layered, segmented, randomized, and blinded trial on three parallel and multiple centered groups was conducted in 480 patients with stable effort angina grade I, II and III, who had two or more times of attack every week. The 240 patients in test group A were treated with SSLA 200 mg added in 250 ml of 5% glucose solution for intravenous dripping every day; the 120 patients in test group B were treated with SSLA but the dosage doubled; and the 120 patients in the control group were treated with DSI 20 ml daily in the same method as SSLA was given. The clinical effectiveness and safety were evaluated after the patients were treated for 14 days. RESULTS The results showed that the markedly effective rate in test groups A, B and control group was 37.45%, 36.75% and 30.09% respectively, while the total effective rate in them was 88.09%, 89.74% and 67.26% respectively. Statistical significance was shown in comparisons of the therapeutic effect between control group with test group A and test group B, with that in the two test groups superior to that in the control group, and non-inferiority trial showed eligibility (P < 0.01). Adverse reaction appeared in 8 patients in the test groups and 2 in the control group. CONCLUSION SSLA has definite therapeutic effect in treating patients with CHD-AP, with its effect not inferior to that of DSI, and no evident toxic-adverse reaction.

Abstract
Lithospermi radix (LR, root of Lithospermum erythrorhizon Siebold. et Zuccarinii) has been used to treat various conditions, such as septic shock, eczema and burns. In this study, the effect of LR on lipopolysaccharide (LPS) and recombinant interferon-gamma (rIFN-gamma)-induced production of nitric oxide (NO) and tumor necrosis factor (TNF)-alpha were examined using mouse peritoneal macrophages. At 0.01-1 mg/ml, LR inhibited the LPS/rIFN-gamma-induced expression of inducible nitric oxide synthase (iNOS) and TNF-alpha release. To clarify the mechanism involved, the effect of LR on the activation of nuclear factor (NF)-kappaB was examined. The LPS/rIFN-gamma-induced activation of NF-kappaB was almost completely blocked by LR at 1mg/ml without cytotoxicity. These findings demonstrate that the inhibition of the LPS/rIFN-gamma-induced production of NO and TNF-alpha by LR involves the inhibition of NF-kappaB activation.

Abstract
Shikonin, isolated from the plant Lithospermum erythrorhizon Sieb. ET Zucc, inhibited tumor cell growth and induced cell death in various tumor cells, with 50% growth inhibition of human cervical cancer cells, HeLa, at 18.9 +/- 1.1 mumol L-1. Treated with 40 mumol L-1 shikonin, HeLa cells underwent marked apoptotic morphological changes such as a round shape, membrane blebbing and apoptotic bodies derived from the fragmented nuclei. Another hallmark of apoptosis, DNA fragmentation, was observed by gel electrophoresis. Shikonin (10 mumol L-1) significantly blocked the transition from G1 to S phase in the HeLa cell cycle. Pan-caspase inhibitor (Z-VAD-FMK), caspase-3 inhibitor (Z-DEVD-FMK) or caspase-8 inhibitor (Z-IETD-FMK) effectively inhibited shikonin-induced cell death, while caspase-1 inhibitor (Ac-YVAD-CMK) and caspase-9 inhibitor (Z-LEHD-FMK) failed to affect cell death. Caspase-3 activity significantly increased within 12 h after shikonin treatment. Reduced expression of inhibitor of caspase-activated deoxyribonuclease (ICAD) after exposure to shikonin for 12 h suggests the resultant activation of caspase-activated deoxyribonuclease (CAD), leading to apoptosis.

Abstract
Shikonin has been demonstrated to exhibit anti-cancer activity, but the underlying mechanisms are poorly understood. In this report, we showed that the administration of shikonin could result in the induction of apoptotic cell death of human hepatoma cell line, SK-Hep-1. As evident by the flow-cytometric studies, shikonin has the capability of generating increased amounts of intracellular reactive oxygen species (ROS) during the early stage of this apoptotic process (ca. one-hour), and subsequently accompanied by the dissipation of mitochondrial transmembrane potential (deltapsi (m)) at 3 hours. Further studies indicated that this apoptotic process could effectively be protected by the pretreatment of shikonin-treated cells with glutathione (GSH) and N-acetylcysteine (NAC), a precursor of GSH, but not by cyclosporin A (CyA), an inhibitor of mitochondrial permeability transition (MPT) pore. These data further proved that ROS-mediated oxidative stress was the pivotal element involved in the induction of apoptosis of SK-Hep-1 cells. Taken together, we suggest that shikonin-induced apoptosis of SK-Hep-1 cells proceeds by an oxidative stress-mediated pathway.

Abstract
In this study we assess the effect of pyrrolizidine alkaloids (PAs) extracted from Lithospermum canescens on the biology of the two-spotted spider mite (Tetranychus urticae Koch). Lithospermum canenscens (Michaux) Lehm. (Boraginaceae) is a common prairie plant also known as Indian paint or hoary puccoon. A mixture of seven PAs with known chemical structures was used in this investigation. Mites treated with PAs showed a high mortality of juveniles, a decrease in female fecundity and a shortened longevity. The intrinsic rate of population increase (r(m)) was used as an indicator of T. urticae population performance after treatment with PAs. The r(m) value obtained with alkaloid-treated leaves was lower than that for mites developing on untreated leaves, which indicates that the mite population would develop much slower on treated plants. The results suggest that further studies should be performed to assess the possible use of PA extracts for spider mite control.

Abstract
The naphthoquinone pigment, shikonin, isolated from Lithospermum erythrorhizon Sieb. et Zucc.(Boraginaceae) and its derivatives are the active components isolated from the Chinese herbal therapeutic, Zicao. Historically, Zicao root extracts have been used to treat macular eruption, measles, sore-throat, carbuncles and burns. Multiple pharmacological actions have been attributed to shikonin, e.g. antiinflammatory, antigonadotropic and anti-HIV-1 activity. In this review, several therapeutic applications of shikonin will be summarized including its pleiotropic, antiinflammatory and antitumour effects. Widely diverse and sometimes conflicting activities have been attributed to shikonin, e.g. wound healing, enhanced granuloma formation, suppression of local acute inflammatory reactions, inhibition of angiogenesis, inhibition of select chemokine ligands, inhibition of DNA topoisomerase activity, inhibition of platelet activation and antimicrobial activity. Comparison of the various reported mechanisms of action for shikonin lead us to hypothesize that shikonin is an effective inhibitor of protein-protein interaction with multiple targets in both the intracellular and extracellular compartments. This general inhibitory effect can account for the broad spectrum of shikonin biological and pharmacological activities.

Abstract
SUMMARY
1. The inhibiting action of extracts of Lithospermum ruderale (lithosperm) when mixed with various hormones has been described.
2. Pituitary gonadotrophin, prolactin (luteotrophin), thyrotrophin and pregnant mares' serum gonadotrophin (PMS) are readily inactivated. Chorionic gonadotrophin is less readily affected, and pituitary growth hormone and ACTH are unaffected by the concentration of lithosperm which inactivates the other hormones. Insulin and posterior pituitary hormones are equally unaffected.
3. PMS 'inactivated' by lithosperm is still capable of causing marked interstitial cell stimulation of the ovary of the intact rat with resulting oestrogen production. Hypophysectomy abolishes this reaction.
4. Various factors influencing the in vitro inactivation have been described, so that a standard method could be developed for testing fractions obtained in purifying lithosperm extracts.
5. Some preliminary extraction methods are discussed.
