Labdane-type diterpene glycosides from fruits of Rubus foliolosus

Article abstract of DOI:10.1248/cpb.39.2443

From fruits of Rubus foliolosus (Rosaceae), a traditional medicine used in Yunnan, China, seven labdane-type diterpene glycosides were isolated. Of these glycosides, five were identified as goshonosides-F1-5 (1 - 5) which have heen isolated from leaves of R. chingii. Structures of two new glycosides, goshonosides-F6 (6) and -F7 (8), were elucidated as α-L-arabinofuranosyl-(1 → 6)-β-D-glucopyranoside of 13(E)-ent-labda-8(17),13-diene-3β,15,18-triol and 3β,15-di-O-β-D-glucopyranoside of 13(E)-ent-labda-8(17),13-diene-3β,15-diol. Goshonosides-F6 (6) and -F7 (8) were also isolated from the leaves of R. chingii.
