UPLC Quantitative Analysis of Multi-Components by Single Marker and Quality Evaluation of Polygala tenuifolia Wild. Extracts.[Pubmed:29261155]
Molecules. 2017 Dec 20;22(12). pii: molecules22122276.
The quality control of Polygala tenuifolia Wild. is a major challenge in its clinical application. In this paper, a new strategy for the quality evaluation of P. tenuifolia extracts was verified through reverse-phase ultra-performance liquid chromatography (UPLC). The quantitative analysis of multi-components by a single marker (QAMS) was conducted with 3,6'-disinapoyl sucrose as an internal reference substance. Eight components (i.e., sibiricose A5, sibiricose A6, Glomeratose A, tenuifoliside A, tenuifoliside B, tenuifoliside C, sibiricaxanthone B, and polygalaxanthone III) were determined based on the relative correction factors. The concentrations of these components were also determined by applying a conventional external standard method. The cosine value confirmed the consistency of the two methods (cosine ratio value >0.999920). Hierarchical cluster analysis, radar plots, and discriminant analysis were performed to classify 23 batches of P. tenuifolia extracts from Shanxi, Hebei, and Shaanxi in China. Results revealed that QAMS combined with radar plots and multivariate data analysis could accurately measure and clearly distinguish the different quality samples of P. tenuifolia. Hence, QAMS is a feasible and promising method for the quality control of P. tenuifolia.
Simultaneous determination of phenols in Radix Polygalae by high performance liquid chromatography: quality assurance of herbs from different regions and seasons.[Pubmed:17722189]
J Sep Sci. 2007 Nov;30(16):2583-9.
Radix Polygalae, roots of Polygala tenuifolia or of Polygala sibirica, is a Chinese herbal medicine commonly used to prevent dementia. Reliable chemical markers for quality assurance of this herb are missing. Here, a high performance liquid chromatography method coupled with diode array detection was developed to simultaneously determine nine different phenols in Radix Polygalae, including sibiricose A(5), sibiricose A(6), Glomeratose A, tenuifoliside A, glomeratose D, 3',6-di-O-sinapoyl sucrose ester, mangiferin, polygalaxanthone III, and polygalaxanthone XI. By using two different detection wavelengths in the HPLC analysis, the developed method was able to determine the phenols with excellent resolution, precision, and recovery. This established method was therefore applied to determine the amounts of phenols in thirty-two samples from different cultivation regions and harvest seasons in China, and significant variations were revealed. The amounts of phenols in the roots of P. tenuifolia collected in Shanxi and Shannxi Provinces were markedly higher than in roots collected from other Provinces. Moreover, the samples harvested in the spring contained higher contents of phenols than those collected in other seasons.
Indole alkaloids and other constituents of Rauwolfia serpentina.[Pubmed:15974606]
J Nat Prod. 2005 Jun;68(6):848-52.
From the dried roots of Rauwolfia serpentina were isolated five new indole alkaloids, N(b)-methylajmaline (1), N(b)-methylisoajmaline (2), 3-hydroxysarpagine (3), yohimbinic acid (4), isorauhimbinic acid (5), a new iridoid glucoside, 7-epiloganin (6), and a new sucrose derivative, 6'-O-(3,4,5-trimethoxybenzoyl)Glomeratose A (7), together with 20 known compounds. The structures of the new compounds were determined by spectroscopic and chemical means. The inhibitory activities of the selected alkaloids on topoisomerase I and II and their cytotoxicity against the human promyelocytic leukemia (HL-60) cell lines were assessed.
Bioactivity screening, extraction, and separation of lactate dehydrogenase inhibitors from Polygala tenuifolia Willd. based on a hyphenated strategy.[Pubmed:28134488]
J Sep Sci. 2017 Mar;40(6):1385-1395.
Stroke is the second leading cause of death worldwide. Lactate dehydrogenase inhibitors are currently widely used in the treatment of ischemic stroke, and natural products are considered promising sources of lactate dehydrogenase inhibitors. In this study, ultrafiltration liquid chromatography coupled with mass spectrometry was used for the screening and identification of lactate dehydrogenase inhibitors from Polygala tenuifolia. Furthermore, five lactate dehydrogenase inhibitors, sibiricose A5, 3,6'-di-O-sinapoyl-sucrose, Glomeratose A, tenuifoliside B, and tenuifoliside C, were selected as target lactate dehydrogenase inhibitors. In addition, the five target compounds with purities of 96.45, 97.65, 96.38, 94.34, and 93.29% were extracted and isolated using a new hyphenated strategy of microwave-assisted extraction coupled with countercurrent chromatography with a two-phase solvent system of n-hexane/n-butanol/ethanol/water (5.321:1.00:1.664:6.647). The bioactivities of the isolated compounds were analyzed using PC12 cells and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The results also demonstrated that microwave-assisted extraction coupled with countercurrent chromatography is an efficient method of isolating chemical constituents from medicinal herbs. Moreover, the research route consisting of activity screening, extraction, separation, and activity verification of the compounds has the advantages of being efficient, orientated, and objective.
