摘要
The isolation and identification of eight xanthones, together with friedelin, from the aerial parts of Hypericum ascyron are reported. One of these xanthones, 3,6-dihydroxy-1,7-dimethoxyxanthone is a new compound and the other 5-chloro-1,6-dihydroxy-3-methoxy-8-methylxanthone is the first chloroxanthone isolated from higher plants.
