1.Bioactivity screening, extraction, and separation of lactate dehydrogenase inhibitors from Polygala tenuifolia Willd. based on a hyphenated strategy.
Li S;Liu S;Liu Z;Liu C;Song F;Pi Z J Sep Sci. 2017 Mar;40(6):1385-1395. doi: 10.1002/jssc.201601216. Epub 2017 Feb 22.
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.

Five new oleanane-type saponins, polygalasaponins XXVIII-XXXII, along with one known saponin, polygalasaponin XXIV, and one known acylated sucrose, tenuifoliside C, were isolated from the root of Polygala japonica. The structures of these new compounds were elucidated as 3-O-beta-D-glucopyranosyl pesenegenin 28-O-beta-D-xylopyranosyl (1-->4)-alpha-L-rhamnopyranosyl (1-->2)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl (1-->5)-beta-D-apiofuranosyl (1-->4)-beta-D-xylopyranosyl (1-->4)-alpha-L-rhamno-pyranosyl (1-->2)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl (1-->4)-beta-D-xylopyranosyl (1-->4)-alpha-L-rhamnopyranosyl (1-->2)-[4-O-p-methoxycinnamoyl]-[beta-D-glucopyranosyl (1-->3)]-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-alpha-L-arabinopyranosyl (1-->3)-beta-D-xylopyranosyl (1-->4)-[beta-D-apiofuranosyl (1-->3)]-alpha-L-rhamnopyranosyl (1-->2)-[4-O-3,4,5-trimethoxycinnamoyl]-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl persenegenin 28-O-alpha-L-arabinopyranosyl (1-->3)-beta-D-xylopyranosyl (1-->4)-[beta-D-apiofuranosyl (1-->3)-alpha-L-rhamnopyranosyl (1-->2)-[4-O-p-methoxycinnamoyl]-[alpha-L-rhamnopyranosyl (1-->3)-beta-D-fucopyranosyl ester, respectively, on the basis of spectroscopic and chemical evidence.
3.[Analysis of influencing factors of secondary metabolites contents in cultivated Polygala tenuifolia].
Pu YJ;Wang DD;Yan Y;Tian HL;Peng B;Qin XM;Ma CG;Du CH;Hu BX;Zhang FS Zhongguo Zhong Yao Za Zhi. 2017 Aug;42(16):3167-3177. doi: 10.19540/j.cnki.cjcmm.2017.0125.
This work was launched to explore the effect of habitat and growth year on the secondary metabolites contents of cultivated Polygala tenuifolia. The samples of cultivated P. tenuifolia were analyzed by ultra-high performance liquid chromatography(UPLC)-quadrupole time-of-flight mass spectrometry(Q-TOF MS), and the obtained data were analyzed using multiple statistical analysis and cluster analysis. The results showed that compared with growth year, habitat is a main influencing factor which affected the secondary metabolites contents of P. tenuifolia. The contents of sucrose esters and oligosacchride multi-esters are greatly dependent on the habitat (the sample-AG with high levels of components of tenuifoliside B and tenuifoliside C, and the sample-FY with high levels of 3,6'-disinapoyl sucrose, tenuifoliose S, tenuifoliose L, and tenuifoliose V). There is no obvious effect of habitat and growth year on xanthone. The contents of triterpene saponins are greatly dependent on the growth year, and the content of parts of triterpene saponins increased as time goes on.The result indicated that the effect of habitat and growth year on different types of secondary metabolites is not completely equivalent.
