摘要： 从云南省永善县产的百合科植物蜘蛛抱蛋(Aspidistra elatior)根状茎中分离得到8个甾体化合物。其中6个为已知的甾体化合物，分别鉴定为(25S)-3β-hydroxy-spirost-5-ene 3-O-β-D-glucopyranosyl(1→)［β-D-xylopyranosyl(1→3)］-β-D-glucopyranosyl(1→4)-β-D-galactopyranoside(1),(25S)-26-O-β-D-glucopyranosyl-furost-5-en-3β,22ζ,26-triol3-O-β-D-glucopyranosyl(1→)［β-D-xylopyranosyl(1→3)］-β-D-glucopyranosyl(1→4)-β-D-galactopyranoside(2), tupiloside H (3), neopentrogenin 5-O-β-D-glucopyranoside(5), tupstroside G(6)和neopentrogenin (7)。化合物4为新的甾体皂甙，命名为蜘蛛抱蛋甙A (aspidoside A)，8为一新的甾体皂甙元硫酸盐，命名为蜘蛛抱蛋甙元A (aspidistrogenin A)。二者的化学结构分别测定为1β,2β,3β,4β,5β-pentahydroxy-spirost-25(27)-ene 5-O-(-D-glucopyranoside和(25S)-spirost-1β,2β,3β,4β,5β-pentol 2-sulfate。化合物1，2，3和6为首次从蜘蛛抱蛋属植物中分离得到。
