Two new compounds, (-)-(6aR,11aR)-4-methoxy-8,9-(methylenedioxy)pterocarpan 3-O-β-D-glucopyranoside (1) and 5-hydroxy-7-methoxyisoflavone 4′-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (2), were isolated, together with 30 known compounds from the stems and leaves of Sophora flavescens Aition. Their structures were elucidated by extensive spectroscopic analysis, including HRESI-MS data. A preliminary comparison of phenolic metabolite profiles, based on the qualitative HPLC analysis, indicated that the composition of the roots and the aerial parts were significantly different. © 2014 PLOS ONE.

A new flavonol glycoside, kaempferol-3-O-β-d-(2-O-E-p-coumaroyl)-glucopyranosyl-7-O-α-l-rhamnopyranoside (1), along with eleven known compounds including five flavonol glycosides (2-6), one phenolic glycoside (7), two megastigmane glycosides (8 and 9), two triterpenoids (10 and 11) and one alditol (12), was isolated from the aerial parts of Euonymus fortunei. Their structures were determined on the basis of spectroscopic analysis and chemical evidence. Compounds 2-4, 7, 8, and 10-12 were evaluated their antimicrobial activities against Ureaplasma urealyticumin vitro, but all tested compounds have no useful activities against Ureaplasma urealyticum. © 2015 Taylor & Francis.
