Abstract A HPLC-DAD method was established for the simultaneous determination of eight components in Leonuri Herba from different habitats, as well as providing methodological reference for quality control of Leonuri Herba. In this study, absolute ethanol extracts of the medicinal material were considered as the sample solutions to be analyzed. Agilent ZORBAX SB-C18 column (250 mm × 4.6 mm, 5 μm) was used for determination maintained at the temperature of 30°C. Gradient elution was performed with a mobile phase of methanol (B)-0.1% phosphoric acid solution (A) at the flow rate of 1.0 mL·min−1. The analysis was carried out at the wavelength of 225, 280 and 320 nm. The measured eight components showed good linear relationships within their own concentration range. Average recoveries ranged from 98.83 to 100.36% with RSDs of 1.14~1.97%. The proposed method was found to be simple, accurate and reproducible, which provided an effective quantitative analytical method for quality control of Leonuri Herba from different habitats.

Introduction. This study aimed at developing an HPLC-DAD method for simultaneous determination of eurycomanone (EU), epimedin C (EC) and icariin (IC) in EE tablets containing Radix Eurycomae longifoliae extract and Herba Epimedii extract (EE tablets). Methods. Several HPLC conditions (detection wavelength, mobile phase) and sample preparation conditions (type of solvent, ratios of tablet powder and solvent) were investigated. Results. The optimized HPLC condition employed a Shim-Pack RP18 column and a detection wavelength of 254 nm. The mobile phase consisted of acetonitrile and water containing 0.1% H3PO4 in gradient elution. The method was selective, linear, precise (RSD < 2%) and accurate with recoveries in the range of 98.51–104.58% for EU, 96.22–104.80% for EC and 97.50–104.96% for IC. Conclusion. The method for simultaneous quantification of EU, EC and IC in EE tablets by HPLC – DAD was developed and validated for the first time and could be applied for quality control of EE tablets.

Background: Zishen Tongguan (ZSTG) capsules were prepared at the Affiliated Hospital of Nanjing University of Chinese Medicine and have been proven to be clinically effective for treating pyelonephritis and benign prostatic hyperplasia. However, the quality standards are not ideal; a comprehensive study of the “quality markers” (Q-markers), the chemicals inherent in traditional Chinese medicine and its preparations, has not been carried out. Experimental Methods: In this paper, a sensitive and specific ultra-high-performance liquid chromatographictandem mass spectrometry (UHPLC-MS/MS) method was developed for the simultaneous determination of eight potential Q-markers of ZSTG, including timosaponin A3, berberine, jatrorrhizine, phellodendrine, palmatine, mangiferin, neomangiferin, and timosaponin BII. A Kromasil 100-3.5 C18 column was used with a mobile phase of 0.2% formic acid with acetonitrile, and gradient elution at a flow rate of 0.2 mL/min was achieved in 13 minutes and used for separation. Detection was performed in positive/negative mode with multiple reaction monitoring (MRM). Results: The analytical method was validated in terms of the sensitivity, linearity, accuracy, precision, repeatability, stability and recovery. The method established here was successfully applied to study the potential Q-markers in 8 batches of commercial samples, which demonstrated its use in improving the quality control of ZSTG. Conclusion: The developed method had high repeatability and accuracy and was suitable for the simultaneous analysis of multiple Q-markers, which may provide a new basis for the comprehensive assessment and overall quality control of ZSTG.

A simple and reliable HPLC method was developed and validated for the simultaneous quantification of four major constituents in Semen Vaccariae. The chromatographic separation was performed on an Agilent Zorbax SB-C18 column with gradient elution using methanol and water. The calibration curves showed good linearity of R2 > 0.9999 with LOQs (S/N = 10) of 0.20–1.16 μg/mL. The precision was evaluated by intra- and inter-day assays and R.S.D. values were less than 2.09%. The recovery rates were between 97.0% and 105.0%. The developed method was applied to the quantitative analysis of Semen Vaccariae and its stir-fried products. During the stir-frying process, vaccarin degraded and yielded isovitexin-2″- O-arabinoside. The preferable stir-frying temperature is around 120°C. The developed HPLC method can be applied to the quality control of crude and stir-fried Semen Vaccariae.

Xinnaoshutong capsule (XC) is a traditional Chinese prescription derived from the ripe fruit of Tribulus terrestris L. (TT). Although XC has long been considered as an important herbal medicine, no analytical method of marker compounds for quality assessment is registered in the Chinese Pharmacopoeia. A simple analytical method of twelve marker components was developed and validated by HPLC-VWD-ELSD method. Chromatographic separation by HPLC was carried out on a Hedera ODS 2 column (4.6 × 250 mm, 5 μm) by gradient elution with acetonitrile-water (0.1% formic acid) as the mobile phase. Various extraction conditions were optimized to achieve twelve marker compounds with faster extraction and higher recovery. The analytical condition was then validated in terms of the linearity, accuracy and precision, repeatability, and stability. The twelve markers were successfully quantified in 30 batches of commercial samples. The developed HPLC-VWD-ELSD could be used as a rapid and reliable way in the assessment and quality control of XC and TT.

Abstract Reserpine-rescinnamine group alkaloids are extracted from Rauwolfia serpentina preparations into dimethylsulfoxide (DMSO)-methanol and diluted with 0.5N H2SO4. The chloroform extract of this solution is passed through a 0.1N NaOH-Celite column and then through a silica gel column. The weakly basic alkaloids trapped on the latter column are eluted with chloroform-methanol; a portion of the eluate is treated with a vanadium pentoxide-phosphoric acid solution, and the reserpine-rescinnamine content is determined by measuring the intensity of the resulting fluorescence. The following means and standard deviations (11 collaborators) were obtained for the determination of reserpine-rescinnamine group alkaloids in 4 samples of Rauwolfia serpentina (NF reference powder, 100 and 50 mg commercial tablets, and 45 mg synthetic tablet formulation) : 0.173%, 0.0050; 0.128%, 0.0030; 0.150%, 0.0069; and 0.142%, 0.0032; respectively. The method has been adopted as official first action.
