The acetone-soluble parts of Garcinia subelliptica leaves were analyzed and six new biflavonoids were isolated, i.e., garciniaflavones A-F (1-6), as well as the five known biflavonoids amentoflavone (7), podocarpusflavone A (8), (+)-morelloflavone (9), (+)-morelloflavone-7"-O-β-glucopyranoside (10), and (+)-4'''-O-methylmorelloflavone (11) and the three triterpenoids oleanan-3-one, β-amyrin, and cycloartenol. The structures of the isolates were established based on spectroscopic analyses… CONTINUE READING
