Kizu H, Hirabayashi S, Suzuki M, Tomimori T
Studies on the constituents of Hedera rhombea Bean. IV. On the hederagenin glycosides. (2)
Chemical and Pharmaceutical Bulletin 33 (1985)
3473-3478
On the basis of chemical and physicochemical evidence, the structures of two new hederagenin bisdesmosides, named Kizuta saponins K_8 (X) and K_<11> (I), which were isolated from the stem and bark of Hedera rhombea BEAN (Araliaceae), were established to be as follows : X, 3-O-α-L-arabinopyranosyl-hederagenin 28-O-α-L-rhamnopyranosyl-(1→4)-6-O-acetyl-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester ; I, 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl-hederagenin 28-O-α-L-rhamnopyranosyl(1→4)-6-O-acetyl-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester. A glucoside mixture (XIII) was considered to be a mixture of the β-D-glucopyranosides of campesterol (trace), stigmasterol and β-sitosterol based on chemical and physicochemical evidence.
