| 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.

| Abstract: | 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-)-b-D-glu- curono- pyranosyl)-oleanolic acid-28-O-a-L-arabinopyranoside(9); 3-O-b-D-glucuropyranosyl oleanolic acid -28-O-b-D-gluco pyranosyl-(16)- b-D-glucopyranoside(15) by spectroscopic and chemical means. |
