Abstract
Four new benzophenone C-glucosides, glomeratides A (1), B (2), C (3), and D (4), along with a known compound arrilanin G (5), have been isolated from the whole plant of Polygala glomerata Lour. Their structures were determined by extensive analyses of their spectral data. Compounds 1–5 showed hepatoprotective activities against d-galactosamine-induced toxicity in WB-F344 rat hepatic epithelial stem-like cells.
