Steroidal saponins from Hemerocallis fulva var. kwanso.
Two steroidal saponins, hemeroside A and B, were isolated from the aerial part of Hemerocallis fulva var. kwanso for the first time. The structures of these compounds were established as 24S-hydroxy-neotokorogenin 1-O-alpha-L-arabinopyranosyl 24-O-beta-D-glucopyranoside (1) and isorhodeasapogenin 3-O-beta-D-glucopyranosyl-(1-->3)-[beta-D-xylopyranosyl-(1-->2)]-beta-D-glucopyranosyl-(1-->4)-beta-D-galactopyranoside (2) through NMR experiments.
