菲吲哚联啶类生物碱(phenanthroindolizidine)主要存在于萝摩科娃儿藤属、鹅绒藤属、Antioxicum,Pergularia等属植物中。另外还从桑科无花果属(Ficus)两种植物及Acanthaceae科Hypoestes属的一种植物中分得。目前已知的该类生物碱共有33种.具有如下的基本母核(图1). 根据该类化合物母核的异构情况及取代基的差别共分为8个组(图2)列于表1中。 Phenoanthin alkaloids (phenanthroindolizidine) are mainly found in plants belonging to the genus Drosophila, genus Goosefoot, Antioxicum, and Pergularia. It is also obtained from two plants of the genus Ficus and Hypoestes from the Acanthaceae family. At present, there are 33 known species of alkaloids, which have the following basic nucleus (Figure 1). According to the heterogeneity of the nucleus and the substituents of the compounds, they are divided into 8 groups (Figure 2). in FIG. 1.
