Nine alkaloids have been isolated from the leaves, stems and roots of Stephania elegans and characterized by physicochemical data and chemical transformation as epihernandolinol (3), N-methylcorydalmine (5), hasubanonin (1), aknadinin (2), cyclanoline (6), magnoflorine (7), isotetrandrine (8), isochondodendrine (9) and cycleanine (10). Although a number of Stephania species (Menispermaceae) have been investigated and a variety of protoberberine, aporphine, bisbenzylisoquinoline and hasubanan types of alkaloids (1 to 10) have been isolated, S. elegans appears to have escaped the attention of chemists and pharmacologists. It was, therefore, thought desirable to investigate, in detail, the alkaloidal constituents of S. elegans. In the present investigation, six tertiary and three quaternary alkaloids have been isolated from the stem, leaves, and roots of S. elegans by extensive column chromatography on neutral alumina and by preparative thin layer chromatography on silica gel-G plates. The alkaloids obtained are given in the order of elution. The first and second alkaloids isolated were hasubanonin (1) and aknadinin (2), well characterized known hasubanan alkaloids isolated earlier from S. hernandifolia (11, 12). The identity of the alkaloids was established by comparison of spectral data and physical constants with those reported for authentic samples.
