Cucurbitacin and Triterpenoid Glycosides from Hemsleya giganthy
摘要:
From rhizomes of Hemsleya giganthy collected in Shichuan of China, 16 compounds were isolated.Among them, three compounds (8, 9, 15) are new natural products called Hemslecins G; Hemsgiganosides A and B; respectively.Their structures were elucidated as 7-hydroxy-23, 24-dihydro-cucurbitacin F-25-O-acetate (8); 3-O-(6'-butyl ester-)-β-D-glu-curono-pyranosyl)-oleanolic acid-28-O-α-L-arabinopyranoside(9); 3-O-β-D-glucuropyranosyl oleanolic acid-28-O-β-D-gluco pyranosyl-(1→6)-β-D-glucopyranoside(15) by spectroscopic and chemical means.
