Abstract
Oleuropein (OLE), the main constituent of Olea europaea, displays pleiotropic beneficial effects in health and disease, which are mainly attributed to its anti-inflammatory and cardioprotective properties. Several food supplements and herbal medicines contain OLE and are available without a prescription. This study investigated the effects of OLE on the main cytochrome P450s (P450s) catalyzing the metabolism of many prescribed drugs. Emphasis was given to the role of peroxisome proliferator-activated receptor α (PPARα), a nuclear transcription factor regulating numerous genes including P450s. 129/Sv wild-type and Ppara-null mice were treated with OLE for 6 weeks. OLE induced Cyp1a1, Cyp1a2, Cyp1b1, Cyp3a14, Cyp3a25, Cyp2c29, Cyp2c44, Cyp2d22, and Cyp2e1 mRNAs in liver of wild-type mice, whereas no similar effects were observed in Ppara-null mice, indicating that the OLE-induced effect on these P450s is mediated by PPARα. Activation of the pathways related to phosphoinositide 3-kinase/protein kinase B (AKT)/forkhead box protein O1, c-Jun N-terminal kinase, AKT/p70, and extracellular signal-regulated kinase participates in P450 induction by OLE. These data indicate that consumption of herbal medicines and food supplements containing OLE could accelerate the metabolism of drug substrates of the above-mentioned P450s, thus reducing their efficacy and the outcome of pharmacotherapy. Therefore, OLE-induced activation of PPARα could modify the effects of drugs due to their increased metabolism and clearance, which should be taken into account when consuming OLE-containing products with certain drugs, in particular those of narrow therapeutic window. SIGNIFICANCE STATEMENT: This study indicated that oleuropein, which belongs to the main constituents of the leaves and olive drupes of Olea europaea, induces the synthesis of the major cytochrome P450s (P450s) metabolizing the majority of prescribed drugs via activation of peroxisome proliferator-activated receptor α. This effect could modify the pharmacokinetic profile of co-administered drug substrates of the P450s, thus altering their therapeutic efficacy and toxicity.

Abstract
Swertiamarin, a typical compound of secoiridiod glycosides with various pharmacological effects which is the major iridoid glicoside of Swertia. In this study, we have established a fast and sensitive LC-MS/MS method. The aim was to conduct pharmacokinetic studies of swertiamarin in vivo of rats. Gentiopicroside was used as internal standard and a C18 column was employed for the separation of analytes. The selected reaction monitoring transitions were m/z 375→177, 357.1→195 for swertiamarin and the internal standard, respectively, in a positive ion mode. The results showed that swertiamarin had a good linearity in the range of 2-8000 ng/mL (r > 0.997) and its limit of detection (LLOD) was 0.5 ng/mL. The developed method subsequently successfully used in the pharmacokinetic study of swertiamarin in rats after oral administration (50, 100, and 150 mg/kg). We obtained a series of pharmacokinetic parameters, and the half-time of swertiamarin was 1 h, while the oral bioavailability was between 5.6-7.6%. Six metabolites of swertiamarin were identified based on accurate mass measurements of protonated molecules and their MS/MS spectrum by ultra-high-performance chromatography/tandem quadrupole time-of-flight mass spectrometry. Furthermore, metabolites were classified into three groups and the metabolic pathway of swertiamarin was proposed. The finding may help for the understanding of effectiveness and safety of swertiamarin.

Abstract
Picroside I and II, iridoid glycosides, are the major active markers of roots and rhizomes of Picrorhiza kurroa (family: Scrophulariaceae). The rhizomes of P. kurroa have been traditionally used to treat worms, constipation, low fever, scorpion sting, asthma and ailments affecting the liver. Various Ayurvedic and herbal preparations are available in the market which contains P. kurroa e.g. Arogyavadhini vati, Tiktadi kwath, Picrolax capsules and suspension. These preparations are used without any significant pharmacokinetics data. Previously, we have reported that oral bioavailability of picroside I and II is low. Most of the iridoid glycosides are primarily metabolized by intestinal microbial flora. So, it is necessary to determine the metabolic profile of picroside I and II and check the correlation with lower bioavailability. Therefore, this study was designed to check metabolic (in vitro and in vivo) profile along with pharmacokinetic profile of picroside I and II. For this, a sensitive and selective LC-ESI-MS method was developed and validated for simultaneous determination of picroside I and II in rat plasma. Chromatographic separations were performed on C18 column. The mobile phase consisted of acetonitrile: 10 mM ammonium acetate buffer [90:10 v/v], pH 3.5. In-vitro Metabolic study was performed on rat liver microsomes and primary hepatocytes. In-vivo pharmacokinetic and metabolic profile of picroside I and II was generated after oral administration of Kutkin (mixture of picroside I and II) to Sprague-Dawley rats. Various pharmacokinetic parameters viz. Cmax, Tmax, AUC(0-t) were determined. In metabolic study, eight metabolites of picroside I and six metabolites of picroside II were identified in vitro, out of which four metabolites for each picroside I and picroside II were identified in vivo.

Abstract
In this study, the effect of D-cellobiose on oral bioavailability of gentiopicroside (GPS) was investigate. The influence of D-cellobiose on GPS was achieved by calculating the residual GPS after being degraded with β-glucosidase or intestinal flora, and the data demonstrated D-cellobiose could inhibit the degradation of GPS in intestines; in bioavailability experiment, D-cellobiose could significantly improve the oral bioavailability (P<0.05) of GPS at the mass ratio of 1∶5, 1∶10 (GPS-D-cellobiose). D-cellobiose applied in this study may improve the oral bioavailability of GPS through delaying the degradation in intestines.

Abstract
In this paper, absorption and pharmacokinetic study of Radix Rehmanniae was studied by liquid chromatography coupled with mass spectrometry method after oral administration to rats. By comparing the chromatograms of ultraviolet, full scan, extracted ion and selective reaction monitoring (SRM) of standard solution, Radix Rehmanniae, blank plasma and rat plasma post drug administration, catalpol and ajugol were found to be the main compounds absorbed from Radix Rehmanniae. Plasma concentrations of aucubin, dihydrocatalpol, rehmannioside A (or rehmannioside B/ melittoside) and rehmannioside D were very low. Quantitative method for catalpol and aucubin and semi-quantitative method for other compounds in rat plasma were established. The pharmacokinetic study of those absorbed components was conducted after oral administration of 6 g x kg(-1) Radix Rehmanniae water extract to rats. Cmax, t(1/2) and AUC(0-infinity) of catalpol and ajugol were (2349.05 +/- 1438.34) and (104.25 +/- 82.05) ng x mL(-1), (0.86 +/- 0.32) and (0.96 +/- 0.37) h, (4407.58 +/- 2734.89) and (226.66 +/- 188.38) ng x h x mL(-1), respectively. tmax was at 1.00 h for catalpol and ajugol. Both catalpol and ajugol were absorbed and excreted rapidly.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qing Ye Dan is a well-known herbal drug that is widely used to treat viral hepatitis in the Yi and Hani minority regions in the Yunnan province of China. MATERIALS AND METHODS An LC-MS/MS method was developed to determine the levels of swertiamarin in rat plasma. Swertiamarin and naringin (internal standard, IS) were extracted from rat plasma using solid-phase extraction (SPE) to purify the samples. The pharmacokinetics of the following different administration methods of swertiamarin in rats were studied: oral administration of swertiamarin alone, a Qing Ye Dan tablet (QYDT) and co-administration of swertiamarin and oleanolic acid, with each method delivering approximately 20mg/kg of swertiamarin. Non-compartmental pharmacokinetic profiles were constructed by using the software DAS (version 2.1.1), and the pharmacokinetic parameters were compared using an unpaired Student's t-test. RESULTS The results showed that the pharmacokinetic parameters Cmax, AUC0-∞, Vz/F and CLz/F were significantly different (P<0.05) among the three types of swertiamarin administration. CONCLUSIONS The data indicate that oleanolic acid and the other ingredients present in QYDT could affect the pharmacokinetic behaviour of swertiamarin in rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gentiopicroside (GPS) is a secoiridoid glucoside isolated from the ethanol extract of Gentianae Radix with a content of 13%, which has been used for centuries in Chinese as a digestive aid. AIM OF THE STUDY This study investigates the pharmacokinetics of GPS and its metabolic pathway for the liver ischemia/reperfusion (I/R) in rats. MATERIALS AND METHODS The experimental animals were anesthetized intraperitoneally (i.p.) with a mixture of urethane (1.0 g/kg) and α-chloralose (0.1 g/kg). A midline laparatomy was performed and the liver hilum was gently exposed. All structures in the portal triad (hepatic artery, portal vein, and bile duct) to the left and median liver lobes were occluded with silk thread for 30 min. Ischemia was followed by a sudden reperfusion after removing the occluding threads. After 60 min reperfusion, the rats received a single intravenous 5 mg/kg dose of GPS. RESULTS The area under concentration curve (AUC) was significantly increased; however, the clearance (Cl) was significantly decreased in the liver I/R rats. Furthermore, after pretreated with SKF-525A (50 mg/kg, i.p.), a cytochrome P450 (CYP) inhibitor, AUC, elimination half-life (t(1/2)) and the mean residence time (MRT) of GPS in rat blood were significantly increased, suggesting that CYP was involved in the metabolism of GPS. For the group without liver I/R, GPS was administered at doses of 5 mg/kg and 100 mg/kg intravenously and orally, respectively. The pharmacokinetic results indicated that the AUC was 565±95.1 and 1163±273 min μg/mL and the t(1/2) of GPS was 71±9 and 106±17 min after intravenous and oral administration, respectively. The oral bioavailability of GPS was 10.3±2.4% in the rats. CONCLUSIONS The status of I/R might prolong the disposition of GPS, and the plasma concentration of GPS in the liver I/R injury rats was significantly increased. The increased body exposure of GPS in the treatment of liver I/R may result from the decreased metabolism of GPS mediated by CYP in the liver.

Abstract
OBJECTIVE To establish a method for quickly investigating the absorption ingredients which could be used as the index of quality control of Gentianae Radix et Rhizoma. METHOD The absorption ingredients of Gentianae Radix et Rhizoma were investigated by using the model of in vitro everted intestinal sac (VEIS). The intestinal sac liquors of jejunum and ileum were collected at 6 intervals (15, 30, 45, 60, 90, 120 min) and gentiopicroside, loganin acid, swertiamarin and sweroside were detected by HPLC as the representative marker. The accumulative absorption quantity of gentiopicroside, loganin acid, swertiamarin and sweroside were calculated, respectively. RESULT Six components could be detected in intestinal sac. In different concentrations of Gentianae Radix et Rhizoma, gentiopicroside and swertiamarin in various intestinal sections were the linear absorption (R2 > 0.9), conformed to zero order absorption rate. In jejunum the constant of absorption rate (Ka) of gentiopicroside and swertiamarin increased with the raised dosage of Gentianae Radix et Rhizoma (P < 0.05), which indicated a passive absorption manner, and the value of Ka of high and middle dosage of those in ileum were higher than that of low dosage, and the difference of Ka between high and middle dosage were not significant, which indicated a positive absorption manner. The Ka of high and middle dosage of sweroside in ileum and jejunum were higher than that of low dosage (P < 0.05), and the difference of Ka between high and middle dosage were not significant, which indicated a positive absorption manner. The Ka of loganin acid in jejunum and ileum increased along with the raised dosage of Gentianae Radix et Rhizoma (P < 0.05), which indicated a passive absorption manner. CONCLUSION SEMAC could be used as a tool to investigate the absorption ingredients of Gentianae Radix et Rhizoma. Drug in intestine sac was selective, and the absorption part of intestine was also different.

Abstract
The purpose of this study is to investigate the transdermal delivery characteristics of Gentiana macrophylla complex components system through different parts of the skin under micro-needles conditions. Two-chamber diffusion cells were used, different parts of isolated skin and micro-needle pretreated isolated mouse skin were applied separately, high performance liquid chromatography (HPLC) similarity evaluation methods were used to evaluate transdermal delivery characteristics of Gentiana macrophylla complex components system on receiving pool and the permeation rate and penetration amount of Gentiopicroside at different parts of mouse skin. In the 24 h, the similarity between receiving fluid which was on passive transdermal delivery and micro-needle transdermal delivery conditions and original fluid were ranged from 83.0% to 98.9%; By the micro-needle pretreatment with different parts of the mouse skin, the time that Gentiana macrophylla complex components system though abdominal skin to the receiving fluid which reached 90% similarity compared with that of original fluid was 4 h, which was 18 h at back skin and 12 h at neck skin separately. Micro-needles can be used as the ideal ingredients for traditional Chinese medicine complex transdermal delivery; transdermal absorption time delay could be greatly reduced and its bioavailability was improved. The permeation rate and similarity to original liquid of Chinese medicine complex components increased significantly in the abdominal skin relative to the neck and back skin under micro-needle conditions.
