Three new quinovic acid glycosides, named gongganosides A (1), B (2), and C (3), were isolated from the bark of Bhesa paniculata (Celastraceae), an Indonesian medicinal plant collected in Sumatra Island. The chemical structures have been elucidated on the basis of chemical and physicochemical evidence as quinovic acid 3-O-beta-D-xylopyranosyl(1-->3)-alpha-L- rhamnopyranoside for 1,28-O-beta-D-glucopyranosylquinovic acid 3-O-alpha-L-rhamnopyranoside for 2, and 28-O-beta-D-glucopyranosyl-quinovic acid 3-O-beta-D-xylopyranosyl(1-->3)-alpha-L-rhamnopyranoside for 3.
