TWO STEROIDAL GLYCOSIDES, ACULEATISIDE A AND B FROM SOLANUM ACULEATISSIMUM

Article abstract of DOI:10.1016/S0031-9422(00)86972-1

Two new steroidal glycosides, named aculeatiside A and B, were isolated in yields of ca 0.1 and 3.0percent, respectively, from the root of Solanum aculeatissimum and their structures were determined as 26-O-β-D-glucopyranosyl nuatigenin 3-O-β-chacotrioside and 26-O-β-D-glucopyranosyl nuatigenin 3-O-β-solatrioside respectively.Therefore, this plant is considered to be a useful source of pregnane derivatives. -- Key Word Index - Solanum aculeatissimum; Solanaceae; steroidal glycosides; aaculeatiside A; aculeatiside B; nuatigenin; isonuatigenin.
