likviriton and ferulic-acid

Xiaoyaosan is one of the famous formulas treating for liver, spleen and blood deficiency syndrome along Chinese history. Their five main components, paeoniflorin, ferulic acid, glycyrrhizic acid, liquiritin, and atractylenolide I are believed to partly representative of this formula. Ultra performance liquid chromatography method was newly established, UPLC BEH-C18 column (2.1 × 100 mm, 1.7 μm) with acetonitrile - 0.1% phosphate acid gradient elution system, in 0.4 mL/min and the temperature was 30 °C; Detection wavelengths were optimized separately. The five components were linear within their linear range (

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

A rapid, highly sensitive, and selective method was applied in a non-invasive way to investigate the antidepressant action of Xiaoyaosan (XYS) using ultra performance liquid chromatography-mass spectrometry (UPLC-MS) and chemometrics. Many significantly altered metabolites were used to explain the mechanism. Venlafaxine HCl and fluoxetine HCl were used as chemical positive control drugs with a relatively clear mechanism of action to evaluate the efficiency and to predict the mechanism of action of XYS. Urine obtained from rats subjected to chronic unpredictable mild stress (CUMS) was analyzed by UPLC-MS. Distinct changes in the pattern of metabolites in the rat urine after CUMS production and drug intervention were observed using partial least squares-discriminant analysis. The results of behavioral tests and multivariate analysis showed that CUMS was successfully reproduced, and a moderate-dose XYS produced significant therapeutic effects in the rodent model, equivalent to those of the positive control drugs, venlafaxine HCl and fluoxetine HCl. Metabolites with significant changes induced by CUMS were identified, and 17 biomarker candidates for stress and drug intervention were identified. The therapeutic effect of XYS on depression may involve regulation of the dysfunctions of energy metabolism, amino acid metabolism, and gut microflora changes. Metabonomic methods are valuable tools for measuring efficacy and mechanisms of action in the study of traditional Chinese medicines.

A simple and accurate high-performance liquid chromatographic method was applied to the quantitative analysis of seven components of the traditional herbal prescription Jaeumganghwa-tang (JGT), including 5-hydroxymethyl-2-furaldehyde, albiflorin, paeoniflorin, liquiritin, ferulic acid, nodakenin, and glycyrrhizin. All seven compounds were separated in less than 40 min on a Gemini C18 column at 40°C by gradient elution using 1.0% (v/v) aqueous acetic acid and acetonitrile containing 1.0% (v/v) acetic acid as mobile phase. The flow rate was 1.0 mL/min and the detector was a photodiode array (PDA) set at 230 nm, 254 nm, 280 nm, and 330 nm. The calibration curves showed good linearity (r (2) > 0.9998) in different concentration ranges. The recovery of each component was in the range of 91.47-102.62%, with relative standard deviations (RSDs, %) less than 4.5%. The RSDs (%) for intra- and interday precision were 0.06-2.85% and 0.06-2.83%, respectively. The concentrations of the seven components in JGT were in the range 0.74-5.48 mg/g.

A high-performance liquid chromatographic (HPLC) method was developed for quantitative analysis of seven components, 5-hydroxymethyl-2-furaldehyde (1), albiflorin (2), paeoniflorin (3), liquiritin (4), ferulic acid (5), nodakenin (6), and glycyrrhizin (7) of Palmul-tang (PMT), a traditional Korean medicine. HPLC analysis was performed using a Gemini C18 column at 40°C, and photodiode array (PDA) detection at 230 nm, 254 nm, 280 nm, 320 nm, and 330 nm was used for quantification of the seven components in PMT. The mobile phase was a gradient flow composed of two solvent systems. Solvent A was 1.0% (v/v) aqueous acetic acid and solvent B was acetonitrile containing 1.0% (v/v) acetic acid. Calibration curves were acquired with r (2) values > 0.9998, and the relative standard deviations (RSDs, %) for intra- and interday precision were both less than 6.0%. The recovery of each component was in the range of 90.66-103.79%, with a RSD less than 5.0%. The contents of the seven components in PMT range form 0.61-6.21 mg/g. Additionally, we investigated the cytotoxicity of the extract against the RBL-1 and BEAS-2B cell lines, as well as splenocytes.

A high performance liquid chromatography coupled with photodiode-array detection method was developed for simultaneous determination of glycyrrhizin, paeoniflorin, benzoic acid, quercetin, ferulic acid, formononetin, liquiritin and isoliquiritigenin in the Chinese proprietary medicine "Xiao Yao Wan" (XYW). The analysis was performed by reverse phase gradient elution, using an aqueous mobile phase (containing 0.1% phosphoric acid) modified by acetonitrile and detection made simultaneously at four wavelengths. The method was validated for accuracy, precision and limits of detection and quantification. Ten batches of XYW obtained from different pharmaceutical companies were analyzed and found to contain different amounts of the eight bioactive markers. This method could be used for quality assessment of this herbal medicine.
