  摘要：

  Abstractmagnified imageTwo new 9,10‐secocycloartane triterpenoidal saponins, named huangqiyenins E (1) and F (2) were isolated from the leaves of Astragalus membranaceus Bunge. Enzymatic hydrolysis of 1 and 2 afforded the aglycones huangqiyegenins III (3) and IV (4), resp. Further alkaline hydrolysis of 3 provided trideacetylhuangqiyegenin III (5). Their structures were established by detailed spectroscopic analysis as (3S,5R,6S,10R,12β,16β,24E)‐26‐(β‐D‐glucopyranosyloxy)‐10,16‐dihydroxy‐4,4,14‐trimethyl‐9,19‐cyclo‐9,10‐secocholesta‐9(11),24‐diene‐3,6,12‐triyl triacetate (1), (3S,5R,6S,10R, 16β,24E)‐26‐(β‐D‐glucopyranosyloxy)‐10,16‐dihydroxy‐4,4,14‐trimethyl‐9,19‐cyclo‐9,10‐secocholesta‐9(11), 24‐diene‐3,6‐diyl diacetate (2), (3S,5R,6S,10R,12β,16β,24E)‐10,16,26‐trihydroxy‐4,4,14‐trimethyl‐9,19‐cyclo‐9,10‐secocholesta‐9(11),24‐diene‐3,6,12‐triyl triacetate (3), (3S,5R,6S,10R,16β,24E)‐10,16,26‐trihydroxy‐4,4,14‐trimethyl‐9,19‐cyclo‐9,10‐secocholesta‐9(11),24‐diene‐3,6‐diyl diacetate (4), and (3S,5R, 6S,10R,12β,16β,24E)‐4,4,14‐trimethyl‐9,19‐cyclo‐9,10‐secocholesta‐9(11),24‐diene‐3,6,10,12,16,26‐hexol (5), resp.
