Abstract
The molecular mechanism underlying the anticancer effects of Anemarrhena asphodeloides (A. asphodeloides) on colon cancer is unknown. This is the first study evaluating the anticancer effect of A. asphodeloides extract (AA-Ex) in serum-starved colorectal cancer cells. Changes in cell proliferation and morphology in serum-starved MC38 and HCT116 colorectal cancer cells were investigated using MTS assay. Cell cycle and apoptosis were investigated using flow cytometry, and cell cycle regulator expression was determined using qRT-PCR. Apoptosis regulator protein levels and mitogen-activated protein kinase (MAPK) phosphorylation were assessed using western blotting. AA-Ex sensitively suppressed proliferation of serum-starved colorectal cancer cells, with MC38 and HCT116 cells showing greater changes in proliferation after treatment with AA-Ex under serum starvation than HaCaT and RAW 264.7 cells. AA-Ex inhibited cell cycle progression in serum-starved MC38 and HCT116 cells and increased the expression of cell cycle inhibitors (p53, p21, and p27). Furthermore, AA-Ex induced apoptosis in serum-starved MC38 and HCT116 cells. Consistently, AA-Ex suppressed the expression of the anti-apoptotic molecule Bcl-2 and upregulated pro-apoptotic molecules (cytochrome c, cleaved caspase-9, cleaved caspase-3, and cleaved-PARP) in serum-starved cells. AA-Ex treatment under serum starvation decreased AKT and ERK1/2 phosphorylation in the cell survival signaling pathway but increased p38 and JNK phosphorylation. Furthermore, AA-Ex treatment with serum starvation increased the levels of the transcription factors of the p38 and JNK pathway. Serum starvation sensitizes colorectal cancer cells to the anticancer effect of A. asphodeloidesvia p38/JNK-induced cell cycle arrest and apoptosis. Hence, AA-Ex possesses therapeutic potential for colon cancer treatment.

Ji KY, Kim KM, Kim YH, Im AR, Lee JY, Park B, Na M, Chae S. The enhancing immune response and anti-inflammatory effects of Anemarrhena asphodeloides extract in RAW 264.7 cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 59:152789. [PMID: 31009851 DOI: 10.1016/j.phymed.2018.12.012] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Revised: 12/07/2018] [Accepted: 12/10/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Anemarrhena asphodeloides has been widely used in traditional medicine for thousands of years; it has been reported to improve learning and memory, and to reduce inflammation. However, the role of A. asphodeloides in enhancing the immune response has remained unclear. PURPOSE This study aimed to evaluate the effect of A. asphodeloides extract (AA-Ex) on enhancing the immune response in macrophages and to identify the active compounds causing these effects. STUDY DESIGN/METHODS To determine the enhancing immune response of AA-Ex and its active compounds, cell proliferation and cell cycle of RAW 264.7 cells were analyzed by MTS assay and flow cytometry. The gene expression of p53, p27, cyclin D2, and cyclin E2 was measured by real-time PCR. To evaluate the anti-inflammatory effects of AA-Ex and its active compounds, the production of nitric oxide (NO), reactive oxygen species (ROS), and pro-inflammatory cytokines was analyzed by Griess reagent, flow cytometry, and real-time PCR. The phosphorylation of p38, c-Jun N-terminal kinase, inhibitory kappa B alpha, and p65 was examined by western blot analysis. RESULTS AA-Ex increased cell proliferation by extending the cell cycle S-phase; timosaponin B and timosaponin B-II affected cell proliferation and the cell cycle as active compounds of A. asphodeloides. Next, we determined that A. asphodeloides displayed anti-inflammatory effects, including the inhibition of the production of NO, ROS, and pro-inflammatory cytokines through the suppression of mitogen-activated protein kinase and nuclear factor kappa B phosphorylation downstream of the toll-like receptor 4 signaling pathway. Moreover, we identified that timosaponin B and timosaponin B-II were the active compounds for these effects. CONCLUSION Our results suggest that A. asphodeloides promotes the immune response and has anti-inflammatory effects. Moreover, timosaponin B and B-II played important roles as the active compounds of A. asphodeloides in enhancing the immune and anti-inflammatory responses in this model.

Permeation characteristics of hypericin across Caco-2 monolayers in the presence of single flavonoids, defined flavonoid mixtures or Hypericum extract matrix. ACTA ACUST UNITED AC 2017; 71:58-69. [PMID: 28294333 DOI: 10.1111/jphp.12717] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Accepted: 02/11/2017] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The major aim of this study was to get a detailed understanding of the exposure and fate of hypericin in the Caco-2 cell system when combined with various flavonoids, mixtures of flavonoids or Hypericum perforatum extract matrix (STW3-VI). METHODS The permeation characteristics of hypericin in the absence or presence of quercetin, quercitrin, isoquercitrin, hyperoside and rutin were tested. Hypericin (5 μm) was mixed with single flavonoids (20 μm) or with different flavonoid combinations (each flavonoid 4 or 10 μm, total flavonoid concentration: 20 μm). Further, the uptake of hypericin (5 μm) in the presence of H. perforatum extract matrix (7.25, 29 and 58 μg/ml) was studied. KEY FINDINGS Following application of hypericin to the apical side of the monolayer, only negligible amounts of the compound were found in the basolateral compartment. From all tested flavonoids, only quercitrin increased the basolateral amount of hypericin. Dual flavonoid combinations were not superior compared to the single combinations. The amount of hypericin in the basolateral compartment increased concentration-dependently in the presence of extract matrix (from 0 to 7.5%). CONCLUSION Comparing the effects of various flavonoid mixtures vs the extract matrix, it can be concluded that, besides flavonoids, the extract seems to contain further compounds (e.g. phenolic acids or proanthocyanidins) which substantially improve the permeation characteristics of hypericin.

Cerebroprotection of flavanol (-)-epicatechin after traumatic brain injury via Nrf2-dependent and -independent pathways. Free Radic Biol Med 2016; 92:15-28.

Abstract
Traumatic brain injury (TBI), which leads to disability, dysfunction, and even death, is a prominent health problem worldwide with no effective treatment. A brain-permeable flavonoid named (-)-epicatechin (EC) modulates redox/oxidative stress and has been shown to be beneficial for vascular and cognitive function in humans and for ischemic and hemorrhagic stroke in rodents. Here we examined whether EC is able to protect the brain against TBI-induced brain injury in mice and if so, whether it exerts neuroprotection by modulating the NF-E2-related factor (Nrf2) pathway. We used the controlled cortical impact model to mimic TBI. EC was administered orally at 3h after TBI and then every 24h for either 3 or 7 days. We evaluated lesion volume, brain edema, white matter injury, neurologic deficits, cognitive performance and emotion-like behaviors, neutrophil infiltration, reactive oxygen species (ROS), and a variety of injury-related protein markers. Nrf2 knockout mice were used to determine the role of the Nrf2 signaling pathway after EC treatment. In wild-type mice, EC significantly reduced lesion volume, edema, and cell death and improved neurologic function on days 3 and 28; cognitive performance and depression-like behaviors were also improved with EC administration. In addition, EC reduced white matter injury, heme oxygenase-1 expression, and ferric iron deposition after TBI. These changes were accompanied by attenuation of neutrophil infiltration and oxidative insults, reduced activity of matrix metalloproteinase 9, decreased Keap 1 expression, increased Nrf2 nuclear accumulation, and increased expression of superoxide dismutase 1 and quinone 1. However, EC did not significantly reduce lesion volume or improve neurologic deficits in Nrf2 knockout mice after TBI. Our results show that EC protects the TBI brain by activating the Nrf2 pathway, inhibiting heme oxygenase-1 protein expression, and reducing iron deposition. The latter two effects could represent an Nrf2-independent mechanism in this model of TBI.

Abstract
Mango seed kernel extract (MSKE) and its key components (gallic acid, GA; methyl gallate, MG; and pentagalloyl glucopyranose, PGG) have generated interest because of their pharmacological activities. To develop the potential use of the key components in MSKE as natural therapeutic agents, their pharmacokinetic data are necessary. Therefore, this study was performed to evaluate the factors affecting their oral bioavailability as pure compounds and as components in MSKE. The in vitro chemical stability, biological stability, and absorption were evaluated in Hanks' Balanced Salt Solution, Caco-2 cell and rat fecal lysates, and the Caco-2 cell model, respectively. The in vivo oral pharmacokinetic behavior was elucidated in Sprague-Dawley rats. The key components were unstable under alkaline conditions and in Caco-2 cell lysates or rat fecal lysates. The absorptive permeability coefficient followed the order MG > GA > PGG. The in vivo results exhibited similar pharmacokinetic trends to the in vitro studies. Additionally, the co-components in MSKE may affect the pharmacokinetic behaviors of the key components in MSKE. In conclusion, chemical degradation under alkaline conditions, biological degradation by intestinal cell and colonic microflora enzymes, and low absorptive permeability could be important factors underlying the oral bioavailability of these polyphenols.

Abstract
OBJECTIVE Digitalis preparations are commonly used by children and adults with heart diseases worldwide, although excessive doses may cause cardiac effects. The aim of the study is to evaluate the antiarrhythmic effect of Crataegus oxyacantha extract on digoxin-induced arrhythmias in anesthetized Wistar rats. METHODS Control and experimental groups were evaluated for arrhythmias induced by digoxin. Fifteen rats (7 as controls and 8 as the experimental group) were included in the study. The dry fruits of 100 mg Crataegus oxyacantha were extracted by percolation method. Digoxin, at a dose of 40 µg/kg/min, was infused to form the arrhythmias in all rats. Simultaneously, the extract was infused into the experimental group, while 0.9% NaCl was infused into control group. Electrocardiographic QRS prolongation and arterial blood pressure changes were analyzed. RESULTS The experimental group lived longer (62.13±2.20 min) than the controls (p=0.002). On the other hand, the time to beginning of QRS prolongation did not differ between the two groups (p=0.812). Bradycardia was significant in the control group (288.01±10.54 beat/min and p=0.01). The maximum QRS duration was observed in the control group during the digoxin and 0.9% NaCl infusion period (53.29±3.99 ms and p=0.001). Also, the durations of atrial and ventricular arrhythmias were shorter in the experimental group. However, arterial blood pressure dipping was significant in the experimental group (23.67±10.89 mm Hg and p<0.001). CONCLUSION Crataegus oxyacantha alcoholic extract produced an antiarrhythmic effect that was induced by digoxin in Wistar rats. However, in the clinical use of this extract, the hypotensive effect should be considered. Also, the alcoholic extract of Crataegus oxyacantha may be an alternative treatment medication for arrhythmias induced by digoxin toxicity in humans.

Abstract
Hawthorn (Crataegus oxyacantha) is a widely used Chinese herb for treatment of gastrointestinal ailments and heart problems and consumed as food. In North America, the role of treatment for heart problems dates back to 1800. Currently, evidence is accumulating from various in vivo and in vitro studies that hawthorn extracts exert a wide range of cardiovascular pharmacological properties, including antioxidant activity, positive inotropic effect, anti-inflammatory effect, anticardiac remodeling effect, antiplatelet aggregation effect, vasodilating effect, endothelial protective effect, reduction of smooth muscle cell migration and proliferation, protective effect against ischemia/reperfusion injury, antiarrhythmic effect, lipid-lowering effect and decrease of arterial blood pressure effect. On the other hand, reviews of placebo-controlled trials have reported both subjective and objective improvement in patients with mild forms of heart failure (NYHA I-III), hypertension, and hyperlipidemia. This paper discussed the underlying pharmacology mechanisms in potential cardioprotective effects and elucidated the clinical applications of Crataegus and its various extracts.

Abstract
The aim of this study is to develop a simple and specific HPLC method using vitexin as the internal standard to investigate the pharmacokinetics of isoquercitrin (ISOQ) after three different doses administrated intravenously to rats. The pharmacokinetic parameters were calculated by both compartmental and non-compartmental approaches. The results showed that ISOQ fitted a three-compartment open model. The values of AUC increased proportionally within the range of 5-10 mg·kg-1. Moreover, a half-life, b half-life, ªCL, MRT0-t and MRT0→∞ of ISOQ in rats showed significant differences between 20 mg·kg-1 and other doses, indicating that ISOQ presented dose-dependent pharmacokinetics in the range of 5-10 mg·kg-1 and non-linear pharmacokinetics at higher doses.

Abstract
Extracts of Crataegus monogyna Jacq. (hawthorn) show an interesting free radical scavenging (FRS) effect, related to their flavonoids content. Unfortunately, their oral administration is affected by their low bioavailability. The aim of this work is to obtain a multiparticulate drug delivery system for hawthorn extracts for oral administration. The extracts from flowering tops (FL) or fruits (FR) of hawthorn were obtained with maceration, using ethanol as an extraction solvent, and their antioxidant activity was evaluated. FL extract showed the highest FRS activity (EC50 3.72 ± 1.21 µg/ml), so it was selected to prepare microparticulate systems by a spray-drying technique, which were characterized by granulometric analysis, scanning electron microscopy-energy dispersive X-ray spectroscopy, confocal fluorescence microscopy and hyperoside content. Antioxidant activity was evaluated before and after gastrointestinal transit in vitro simulation. Results indicate that the microparticulate systems maintained the antioxidant activity of hawthorn also after gastrointestinal transit in vitro simulation, exhibiting properties suitable for oral administration.

Abstract
Herbal supplements hawthorn and ashwagandha (Indian ginseng) are indicated for cardiac illnesses and may be taken by patients receiving digoxin therapy. Because both hawthorn and ashwagandha are known to interfere with serum digoxin measurements using certain digoxin immunoassays, we investigated potential interference of these two herbal supplements with the new homogenous sequential chemiluminescent assay for digoxin based on the luminescent oxygen channeling technology (LOCI digoxin) for application on the Dimension and Vista platform. When aliquots of a drug-free serum pool were supplemented with various amounts of hawthorn (three different commercial preparations) or ashwagandha (two different commercial preparations) and apparent digoxin values were measured using LOCI digoxin assay on Dimension Vista 1500 analyzer we observed none-detected values except when aliquots were supplemented with very high amounts of the herbal extracts. When aliquots of a serum digoxin pool (prepared by pooling specimens from patients receiving digoxin) where further supplemented with various amounts of these supplements and digoxin concentrations were remeasured, statistically significant falsely higher digoxin values were observed only in specimens containing very high amounts of these supplements. Such interference may not be clinically significant. We conclude that new LOCI digoxin assay is virtually free from interferences of herbal supplements, hawthorn, and ashwagandha.

Effect of hawthorn standardized extract on flow mediated dilation in prehypertensive and mildly hypertensive adults: a randomized, controlled cross-over trial. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 12:26.

Abstract
Background Hawthorn extract has been used for cardiovascular diseases for centuries. Recent trials have demonstrated its efficacy for the treatment of heart failure, and the results of several small trials suggest it may lower blood pressure. However, there is little published evidence to guide its dosing. The blood pressure lowering effect of hawthorn has been linked to nitric oxide-mediated vasodilation. The aim of this study was to investigate the relationship between hawthorn extract dose and brachial artery flow mediated dilation (FMD), an indirect measure of nitric oxide release. Methods We used a four-period cross-over design to evaluate brachial artery FMD in response to placebo or hawthorn extract (standardized to 50 mg oligomeric procyanidin per 250 mg extract). Randomly sequenced doses of hawthorn extract (1000 mg, 1500 mg, and 2500 mg) and placebo were assigned to each participant. Doses were taken twice daily for 3 1/2 days followed by FMD and a 4-day washout before proceeding to the next dosing period. Results Twenty-one prehypertensive or mildly hypertensive adults completed the study. There was no evidence of a dose-response effect for our main outcome (FMD percent) or any of our secondary outcomes (absolute change in brachial artery diameter and blood pressure). Most participants indicated that if given evidence that hawthorn could lower their blood pressure, they would be likely to use it either in conjunction with or instead of lifestyle modification or anti-hypertensive medications. Conclusion We found no evidence of a dose-response effect of hawthorn extract on FMD. If hawthorn has a blood pressure lowering effect, it is likely to be mediated via an NO-independent mechanism. Trial Registration This trial has been registered with ClinicalTrials.gov, a service of the U.S. National Institutes of Health: NCT01331486.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) formulas have been widely used in China since ancient times to treat certain diseases (e.g., phlegm, dampness and blood stasis). Recently, the effects of these medicines have been increasingly demonstrated to be helpful for hyperlipidemic patients. AIM OF THE STUDY This manuscript aims to describe the scientific evidence for the efficacy of TCM and attempts to identify potential TCM formulas for treating hyperlipidemia. MATERIALS AND METHODS TCM formulas approved by the State Food and Drug Administration of China (SFDA) were sourced from the official SFDA website (http://www.sda.gov.cn/). Human and animal evidence for the hypolipidemic effects of herbs from TCM formulas were reviewed via the Internet (Elsevier, ACS, Wiley Online Library, SpringerLink, PubMed, Web of Science, CNKI, Baidu, and Google) and libraries up to October 31, 2011. RESULTS More than 50 TCM formulas have been used to treat hyperlipidemia. These herbs can primarily be grouped into three categories: (1) herbs promoting excretions, generally by reducing food retention, enhancing purgative effects, and promoting diuresis and choleretic effects, e.g., Fructus Crataegi (), Radix Polygoni Multiflori (), Semen Cassiae (), and Radix et Rhizoma Rhei (), Rhizoma alismatis (), and Herba Artemisiae Scopariae (); (2) herbs acting on the cardiovascular system, generally by improving blood circulation based on TCM theories, e.g., Radix Salviae Miltiorrhizae (), Radix Puerariae (), Rhizoma Chuanxiong (), Flos Carthami (), and Folium Nelumbinis (); and (3) herbs that have tonic effects, e.g., Fructus Lycii (), Radix Ginseng (), and Radix Astragali (). CONCLUSIONS Three basic approaches, including excretory function enhancement, cardiovascular system improvement, and tonic effect reinforcement, are emerging among TCM formulas for the treatment of hyperlipidemia. These approaches may be useful in controlling blood lipid levels, preventing cardiovascular complications, and adjusting bodily functions in hyperlipidemic patients. However, solid evidence of the efficacy of these treatments is required.

Abstract
Radix Scutellariae is the dried root of the medicinal plant Scutellariae baicalensis Georgi. It exhibits a variety of therapeutic effects and has a long history of application in traditional formulations as well as in modern herbal medications. It has been confirmed that flavonoids are the most abundant constituents and induce these therapeutic effects. Six flavones are proven to be the major bioactive flavones in Radix Scutellariae existing in the forms of aglycones (baicalein, wogonin, oroxylin A) and glycosides (baicalin, wogonoside, oroxylin A-7-glucuronide). All six flavones are pharmacologically active and show great potential in the treatment of inflammation, cancers and virus-related diseases. The current review covers the preparation of the herb Radix Scutellariae, quantification of its major bioactive ingredients, and pharmacological effects of the proposed six bioactive flavones. In addition, this review summarizes the pharmacokinetic profiles of the bioactive flavones reported so far that could be used for further improvement of their pharmacokinetic study. Moreover, due to abundant co-occurring bioactive components in Radix Scutellariae, our review further documents the pharmacokinetic interactions among them.

Abstract
The infusions and extracts obtained from leaves with flowers, fruit peel, and seed from hawthorn (Crataegus monogyna Jacq., Family Rosaceae) were subjected to evaluation as potential sources of antioxidant phytochemicals on the basis of their total content of phenolics, levels of phenolic acids, and in vitro antiradical activity. Total phenolic content of extracts was determined using the modified Folin-Ciocalteau method. Antioxidant activity was determined for phenolic extracts by a method involving the use of the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). Phenolic acids containing extracts and infusions from hawthorn leaves, fruit peel, and seeds were obtained using different polarity solvents and separated by reverse-phase high-performance liquid chromatography, which enabled improved separation by the use of a C(18) column, an acidic mobile phase, and gradient elusion. The highest total phenolic content (343.54 mg of gallic acid equivalents/g) and the highest DPPH radical scavenging activity as the inhibition percentage (60.36%) were obtained in ethyl acetate extract from hawthorn leaves with flower. Also, the highest phenolic acid content was measured in the extracts of hawthorn leaves with flowers: protocathechuic (108-128 mg/100 g), p-hydroxy benzoic (141-468 mg/100 g), caffeic (137-3,580 mg/100 g), chlorogenic (925-4,637 mg/100 g), ferulic (3,363-3,462 mg/100 g), vanillic (214 mg/100 g), and syringic (126 mg/100 g) acids. The results indicate that hawthorn is a promising plant because of its high antioxidant activity.

Abstract
CONTEXT Hawthorn is an herb indicated for treating cardiac illness. Because a patient taking digoxin may also take hawthorn, we investigated potential interference of hawthorn in serum digoxin measurements using immunoassays as well as pharmacodynamic interaction between hawthorn and digoxin. Hawthorn contains alkaloids that are structurally similar to digoxin and may interfere with serum digoxin measurement using immunoassays. In addition, hawthorn has cardioactive properties similar to digoxin. OBJECTIVE To study potential pharmacodynamic interaction between hawthorn and digoxin. DESIGN The effects of hawthorn extract on serum digoxin measurements using Digoxin III (Abbott Laboratories, Abbott Park, Illinois) and the Tina-Quant digoxin assay (Roche Diagnostics, Indianapolis, Indiana) were investigated using 2 different brands of extract. To study the pharmacodynamic interaction between hawthorn and digoxin, we used an isolated adult rat cardiomyocyte system, measuring calcium transients by real-time fluorescence spectrophotometry. RESULTS Hawthorn interfered only with the Digoxin III immunoassay but had no effect on the Tina-Quant assay. Both hawthorn extracts increased intracellular calcium levels, but the lack of additive response with digoxin suggests both may bind to the same site of Na, K adenosine triphosphatase. CONCLUSION Because of interference of hawthorn with a digoxin immunoassay and pharmacodynamic interaction with digoxin, a patient receiving digoxin should avoid hawthorn.

Abstract
The medicinal properties of hawthorn (Crataegus spp., a genus comprising approximately 300 species) have been utilized by many cultures for a variety of therapeutic purposes for many centuries. In the Western world cardiovascular disease (CVD) has become one of the single most significant causes of premature death. Echoing this situation, more recent research into the therapeutic benefits of hawthorn preparations has focused primarily upon its cardiovascular effects. This review covers research into the various mechanisms of action proposed for Crataegus preparations, clinical trials involving Crataegus preparations, and the herb's safety profile.Clinical trials reviewed have been inconsistent in terms of criteria used (sample size, preparation, dosage, etc) but have been largely consistent with regard to positive outcomes. An investigation into data available to date regarding hawthorn preparations and herb/drug interactions reveals that theoretical adverse interactions have not been experienced in practice. Further, adverse reactions relating to the use of hawthorn preparations are infrequent and mild, even at higher dosage ranges. A recent retrospective study by Zick et al. has suggested a negative outcome for the long-term use of hawthorn in the prognosis of heart failure. These findings are examined in this paper.Although further research is needed in certain areas, current research to date suggests that hawthorn may potentially represent a safe, effective, nontoxic agent in the treatment of CVD and ischemic heart disease (IHD).

Abstract
The current study aims to investigate the effect of sodium caprate on the intestinal absorption and bioavailabilities of danshensu and salvianolic acid B, the major active components in Salvia miltiorrhiza Bge (Danshen). Biopharmaceutics and pharmacokinetics properties of the two compounds have been characterized by in vitro, in situ models as well as in vivo in rats. Based on the identified biopharmaceutics characteristics of the two compounds, effect of sodium carparate as absorption enhancer on the intestinal absorption and pharmacokinetics of danshensu and salvianolic acid B in pure compound form as well as extract form were investigated both in vitro and in vivo. Both danshensu and salvianolic acid B demonstrated very limited intestinal permeabilities, leading to oral bioavailabilities of only 11.09% and 3.90% in rats, respectively. Results from both in vitro and in vivo studies consistently indicated that sodium caprate could significantly enhance intestinal permeabilities as well as the in vivo bioavailabilities of both danshensu and salvianolic acid B. The current findings not only identified the usefulness of sodium caprate for the improved delivery of Danshen product but also demonstrated the importance of biopharmaceutics characterization in the dosage form development of traditional Chinese medicine.

Abstract
Cocoa, a product consumed since 600 BC, is now a subject of increasing interest because of its antioxidant properties, which are mainly attributed to the content of flavonoids such as ( - )-epicatechin, catechin and procyanidins. Moreover, recent findings suggest a regulatory effect of cocoa on the immune cells implicated in innate and acquired immunity. Cocoa exerts regulatory activity on the secretion of inflammatory mediators from macrophages and other leucocytes in vitro. In addition, emerging data from in vivo studies support an immunomodulating effect. Long-term cocoa intake in rats affects both intestinal and systemic immune function. Studies in this line suggest that high-dose cocoa intake in young rats favours the T helper 1 (Th1) response and increases intestinal gammadelta T lymphocyte count, whereas the antibody-secreting response decreases. The mechanisms involved in this activity are uncertain; nonetheless, because redox-sensitive pathways control immune cell function, the action of cocoa flavonoids on modulating cell signalling and gene expression deserves investigation.

Abstract
AIM OF STUDY Hawthorn (Crataegus) has a long history as a medicine. The current clinical use of hawthorn as a heart medicine dates back to the late 19th century. It is well tolerated clinically yet contraindicated in pregnancy. MATERIALS AND METHODS To determine the safety of hawthorn to the developing fetus, pregnant rats were dosed daily by gavage using 56 times the human dose of hawthorn on either gestation days (GD) 1-8 or GD 8-15. On GD 20, fetuses were weighed and examined for signs of external, internal or skeletal malformations. Rat fetuses were also explanted on GD 10.5 and cultured with hawthorn extract for 26 h. RESULTS Hawthorn did not have an adverse effect on embryonic development in vivo or in vitro. CONCLUSIONS While the results suggest that hawthorn, taken at the recommended dose would have no adverse effects on embryonic development this may be due to the low bioavailability of some hawthorn constituents when taken orally. Pharmacokinetic studies are required to determine the extent of absorption of hawthorn from the small intestine in healthy adults in order to verify its safety.

Abstract
The present study was to investigate the pharmacokinetics of the two similar flavonoid glycosides, vitexin-4''-O-glucoside (VGL) and vitexin-2''-O-rhamnoside (VRH) in rats after intravenous administration of hawthorn leaves flavonoids (HLF). Blood samples were collected via tail vein at time intervals after drug administration and the plasma concentrations of the studied ingredients were analyzed by HPLC after the plasma protein was precipitated directly with methanol. VGL and VRH were successfully separated using a C(18) column with a UV detection at 330 nm and a mobile phase of methanol-acetonitrile-tetrahydrofuran-0.5% acetic acid (1:1:19.4:78.6, v/v/v/v). The assay linearities of VGL and VRH were confirmed over the range 0.23-138.42 and 0.36-218.49 microg/ml, respectively. The accuracy and precision of the two analytes at high, medium and low concentration were within the range of -3.13% to 3.51% and below 4%, the mean assay recoveries of them (n=5) ranged from 96.87% to 101.75% and 96.88% to 103.51% for intra- and inter-day assays and the mean extraction recoveries of them (n=5) varied from 92.68% to 95.74% for VGL and 93.45% to 99.26% for VRH, respectively. After intravenous administration of HLF to rats over the doses range of 10-40 mg/kg, the plasma concentration--time curves of VGL and VRH were both conformed to the three-compartment open pharmacokinetic model and linear pharmacokinetic characteristics.

Abstract
Our previous studies identified hyperoside (HP), isoquercitrin (IQ) and epicatechin (EC) to be the major active flavonoid components of the hawthorn phenolic extract from hawthorn fruits demonstrating inhibitory effect on in vitro Cu(+2)-mediated low density lipoproteins oxidation. Among these three hawthorn flavonoids, EC was the only one detectable in plasma after the oral administration of hawthorn phenolic extract to rats. The present study aims to investigate the intestinal absorption mechanisms of these three hawthorn flavonoids by in vitro Caco-2 monolayer model, rat in situ intestinal perfusion model and in vivo pharmacokinetics studies in rats. In addition, in order to investigate the effect of the co-occurring components in hawthorn phenolic extract on the intestinal absorption of these three major hawthorn flavonoids, intestinal absorption transport profiles of HP, IQ and EC in forms of individual pure compound, mixture of pure compounds and hawthorn phenolic extract were studied and compared. The observations from in vitro Caco-2 monolayer model and in situ intestinal perfusion model indicated that all three studied hawthorn flavonoids have quite limited permeabilities. EC and IQ demonstrated more extensive metabolism in the rat in situ intestinal perfusion model and in vivo study than in Caco-2 monolayer model. Moreover, results from the Caco-2 monolayer model, rat in situ intestinal perfusion model as well as the in vivo pharmacokinetics studies in rats consistently showed that the co-occurring components in hawthorn phenolic extract might not have significant effect on the intestinal absorption of the three major hawthorn flavonoids studied.

Abstract
This study aimed to investigate the effect of co-occurring components from green tea on the intestinal absorption and disposition of green tea polyphenols (GTPs) using the Caco-2 cell monolayer model. The absorption and secretion transport of the four GTPs, in the form of individual pure compounds, pure compound mixtures and green tea extract, were studied in the Caco-2 cell model. Four GTPs and their metabolites were analysed by HPLC/MS and HPLC coupled with electrochemical detector. The apparent permeability coefficients (P(app)) of each compound, as well as the metabolites (mainly sulfation and methylation conjugates) generated, were compared for the different dosing formulations utilized. The results showed that the absorption transport of the four GTPs in different dosing formulations was similar. However, the secretion transport profiles of (-)-epicatechin (EC), (-)-epigallocatechin (EGC) and (-)-epigallocatechin gallate (EGCG) were altered when the GTP mixture was administered. It was suggested that transporter competition resulting in reduced efflux of EC, as well as metabolic competition resulting in reduced formation of EGC sulfate and methylated EGC sulfate, might be involved during the secretion transport of GTP mixture.
