Anti-inflammatory, analgesic and antipyretic activities of the extract of gamboge from Garcinia hanburyi Hook f.
Ampai Panthong,Pinpaka Norkaew,D. Kanjanapothi,T. Taesotikul,Natthinee Anantachoke,Vichai Reutrakul +5 more
TL;DR: It is postulated that the anti-inflammatory, analgesic and antipyretic activities of GH5763 are caused by the inhibition of the prostaglandin biosynthesis.

Tetraoxygenated xanthones from the fruits of Garcinia cowa
TL;DR: Tetraoxygenated xanthones, cowaxanthones A-E, together with 10 previously reported tetraoxyGENated x anthones, were isolated from the crude hexane extract of the fruits of Garcinia cowa by analysis of spectroscopic data, especially by 1D and 2D NMR.
