DITERPENE GLYCOSIDES FROM SENECIO RUFUS

Article abstract of DOI:10.1016/0031-9422(92)80122-U

Two new diterpene glycosides, named rufusoside A and B were isolated from Senecio rufus.Their structures have been established as ent-15α-(α-L-arabinopyranosyloxyl)-kaur-16-en-19-oic acid and ent-15α-(α-L-arabinopyranosyloxyl)-kaur-16-en-19-oic acid-β-D-glucopyranosyl ester, respectively, mainly through interpretation of their spectroscopic data.Key Word Index - Senecio rufus; Compositae; Rufusoside A and B; diterpenoid; glycoside; aglycone.
