From the rhizomes of Hemsleya amabilis, three saponins of oleanolic acid were isolated, named hemslosides-Am1, -Ma1 and -Ma3. Their structures have been elucidated as 3-O-α-arabinopyranosyl (1→3)- β-glucuronide of oleanolic acid, 28-O-β-D-glucopyranosyl ester of oleanolic acid 3-O-α-arabinopyranosyl (1→3)-β-glucuronide and 28-O-β-D-glucopyranosyl ester of oleanolic acid 3-O-[β-glucopyranosyl(1→2)]-[α-arabinopyranosyl(1→3)]-β-glucuronide, respectively. In addition, cucurbitacins, cucurbitacin Ⅱ glycoside, oleanolic acid and β-sitosterol were obtained.
