摘要
从蜘蛛抱蛋（ＡｓｐｉｄｉｓｔｒａｅｌａｔｉｏｒＢｌ．）根茎的甲醇提取物中分离得两个甾体皂甙。经波谱解析及化学降解证明其化学结构分别为薯芋皂甙元一３一Ｏ－［Ｂ－Ｄ－葡萄吡喃糖基（１→２）］－［Ｂ－Ｄ－木吡喃糖基（１→３）］－Ｂ－Ｄ－葡萄吡喃糖基（１→４）－Ｂ－Ｄ一半乳吡喃糖甙（即蜘蛛抱蛋甙ａｓｐｉｄｉｓｔｒｉｎ）及新静诺特皂甙元－３－Ｏ－［Ｂ－Ｄ－葡萄吡喃糖基（１→２）］～［Ｂ－Ｄ－木吡喃糖基（１→３）－Ｂ－Ｄ－葡萄吡喃糖基（１→４）一Ｂ－Ｄ－半乳吡喃糖甙，后者为一新试，命名为新蜘蛛抱蛋甙ｒｅｏａｓｐｉｄｉｓｔｒｉｎ。
Two steroidal saponins were isolated from the rhizome of Aspidistra elattor. On the basis of detailed chemical and spectra scopic evidence, their structures were elucid ated to be diosgenin一3一O一[B一D一glucopyranosyl(1→2)]一[B-D-xylopyranosyl(1→3)]-B-d-glue copyrano-syl(1→4)-B-D-galactopyranoside(aspidistrin) and neobotogenin-3-O-[B-D-glucopyranosyl(1→2)]-[B-D-xylopyranosyl(1→3)]-B-D-glucopyranosyl(1→4)-B-D-galactopyranoside respectively.The latter is new steroidal saponin and named a neoaspidistrin。
