Triterpenoid saponins from the aerial parts of Lonicera japonica

초록

Two new triterpenoid saponins, loniceroside A and B, were isolated from the aerial parts of Lonicera japonica. Their structures were established as 3-O-α-l-arabinopyranosyl hederagenin 28-O-α-l-rhamnopyranosyl (1→2)-[β-d-xylopyranosyl(1→6)]-β-d-glucopyranosyl ester and 3-O-α-l-rhamnopyranosyl(1→2)-α-l-arabino- pyranosyl hederagenin 28-O-α-l-rhamnopyranosyl(1→2)-[β-d-xylopyranosyl(1→ 6)]-β-d-glucopyranosyl ester, respectively. © 1994.
