Abstract A new alkaloid solanaviol ((22 R , 25 R )-spirosol-5-ene-3β,12β-diol) was isolated from Solanum aviculare in addition to solasodine as one of the main alkaloids. The structure of solanaviol was established by NMR spectroscopy, as well as by conversion into a known pregnane derivative and solasodine.
摘要 以茄子碱为主要生物碱之一,从茄属植物中分离得到一种新的生物碱茄碱((22 R , 25 R )-spirosol-5-ene-3β,12β-diol)。茄子醇的结构是通过核磁共振光谱确定的,以及通过转化为已知的孕烷衍生物和茄碱。
