曾从蒟蒻薯(Tacca chantrieri)根茎中分离得到二芳基庚酯、二芳基庚酯糖苷、甾族糖苷等。本次从其根茎的甲醇提取物中分离得到3个新的C28-甾醇寡糖苷,将其命名为taccasterosides A～C(1～3)。取蒟蒻薯根茎(7.3kg)的甲醇提取物(630g),上Diaion HP-20柱,甲醇洗脱部分(115g)过硅胶
Diarylheptyl esters, diarylheptyl glycosides, steroidal glycosides and the like have been isolated from the roots of Tacca chantrieri. Three new C28-sterol oligoglycosides were isolated from the methanol extract of their rhizomes and designated as taccasterosides A to C (1-3). Take the vinegar (7.3kg) methanol extract (630g) on the Diaion HP-20 column and the methanol elution (115g) over the silica gel.
