Indonesian Medicinal Plants. X. Chemical Structures of Four New Triterpene-Glycosides, Gongganosides D, E, F, and G, and Two Secoiridoid-Glucosides from the Bark of Bhesa paniculata (Celastraceae).
Fournew triterpene-glycosides, named gongganosides D (4), E (5), F (6), and G (7), and two new secoiridoid-glucosides, (7R)-7-caffeoyloxysweroside (8) and (7S)-7-caffeoyloxysweroside (9), were isolated from the bark of the Indonesian medicinal plant Bhesa paniculata (Celastraceae). The chemical structures have been elucidated on the bases of their chemical and physiocochemical properties.
