摘要：

The biosynthetic origins of the tetralone isoshinanolone and the related naphthoquinone plumbagin were investigated by feeding [C-13(2)]-acetate to suspended callus cultures of Ancistrocladus heyneanus. The orientation of the acetate subunits was elucidated by a similar experiment using [2-C-13]-acetate. The polyketide folding mode found for isoshinanolone and plumbagin constitutes a further hint at the acetogenic nature of the naphthylisoquinoline alkaloids, which are typical of A. heyneanus and other species of Ancistrocladaceae and Dioncophyllaceae.
