摘要
从云南民间药物大花双参(Triplostegia grandiflora Gagnep.)(川续断科)的根中分离到一个新的二聚环烯醚萜甙,命名为大花双参甙A(triplostoside A)(l),通过化学降解,光谱分析以及核磁共振二维谱技术研究确定了其化学结构。同时,还分离到已知的甲基马钱素(methylloganin)(2),马钱酸(Leganic acid)(3)和青叶胆苦甙(sweroside)(4)。此外还分离到胡罗卜甙(daucosterol)。
A new bis-iridoidal glycoside. triplostoside A have been isolated from the roots of Triplostegia grandiflora Gagnep. (Dipsacaceae) along with the known iridoids, methyl loganin, loganic acid, sweroside and daucosterol. Its structure was elucidated on the basis of spectral data and chemical evidence.
