Triterpenes from ficus ampelas
Ficus ampelas, a Philippine medicinal plant also known as upling gubat, was studied for its chemical constituents. The dichloromethane extract of the air-dried stems of F. ampelas afforded a 2:1 mixture of oleanolic acid (1) and ursolic acid (2). The dichloromethane extract of the air-dried leaves o...
