Two new triterpenoid glycosides, 3α,19α,23α-trihydroxy-2-oxo-12-ursen-28-O-β-d-glucopyranoside (1) and 3α,19α,23α-trihydroxy-2-oxoolean-12-en-28-O-β-d-glucopyranoside (2) as well as three known compounds, 2α,3α,19α-trihydroxyolean-12-en-28-O-β-d-glucopyranoside (3), 2α,3α,19α,23-tetrahydroxy-12-ursen-28-O-β-d-glucopyranoside (4), and 2α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid (5) were isolated from 75% EtOH extract of Rosa cymosa. Their structures were elucidated by extensive spectroscopic methods. All the isolated compounds displayed moderate inhibitory activity against LPS-induced NO production in macrophages. © 2016 Verlag Helvetica Chimica Acta AG, Zürich

Two new arylnaphthalene lignan glycosides, named reticulatusides A (1) and B (2), together with eight known compounds were isolated from the 95% EtOH extract of the whole plant of Phyllanthus reticulatus. The structures of the new compounds were elucidated by spectroscopic methods. © 2012 Copyright Taylor and Francis Group, LLC.

A new purine derivative, 3-(3-methylbut-2-en-1-yl)isoguanine (1), and a new cleistanthane-type diterpenoid glucoside, 19-hydroxyspruceanol 19-O-β-D-glucopyranoside (2), together with eight known compounds were isolated from the whole plant of Phyllanthus reticulatus. The structures were elucidated by chemical and spectroscopic methods. © Copyright 2010 Verlag Helvetica Chimica Acta AG, Zürich, Switzerland.

Bioassay directed isolation of the EtOAc extract from a traditional Chinese medicine Psoralea corylifolia resulted in the purification of two isoflavonoids, corylifols D (1) and E (2), along with four known ones. The structures of 1 and 2 were determined by extensive 1D and 2D NMR and MS data analyses. When tested against HepG2 and Hep3B hepatocellular carcinoma cell lines, corylifol A (4) displayed IC50 values of 4.6 and 13.5 μg/ml, respectively. © 2013 Copyright Taylor and Francis Group, LLC.
