Four new glycosides, pleurofranosides I-IV, together with eight known compounds were isolated from the whole plants of Pleurospermum franchetianum Hemsl. Based on the spectral data and chemical evidence, the structures of pleurofranosides I, II, III and IV were elucidated to be 16 β, 21 β, 23, 28-tetrahydroxyolean-12-ene-3 β-yl- O - β- d -glucopyranosyl-(1 →2)- β- d -glucopyranoside, 13 β, 28-epoxy-16 β, 23-dihydroxyolean-11-ene-3 β-yl- O - β- d -glucopyranosyl-(1 →4)-[ β- d -glucopyranosyl-(1 →2)]- β- d -fucopyranoside, 13 β, 28-epoxy-16 β, 23-dihydroxyolean-11-ene-3 β-yl- O - β- d -glucopyranosyl-(1 →4)-[ β- d -fucopyranosyl-(1 →2)]- β- d -glucopyranoside and 13 β, 28-epoxy-16 β, 23-dihydroxyolean-11-ene-3 β-yl- O - β- d -glucopyranosyl-(1 →3)-[ β- d -glucopyranosyl-(1 →2)]- β- d -glucopyranoside. The known compounds identified were octadecyl caprate, β-sitosterol, (22 E , 20 S , 24 R )-5 α, 8 α-epidioxy-ergosta-6, 22-dien-3- β-ol, daucosterol, α-spinasterol-3- O - β- d -glucopyranoside, quercetin-3, 7-di- O - β- d -glucopyranoside, kaempferol-3, 7-di- O - α- l -rhamnopyranoside and kaempferol-3- O - β- d -glucopyranosyl-7- O - α- l -rhamnopyranoside, respectively. |
