Skimmianine isolated from Skimmia plants fed with anthranilic acid (T), acetate (1-14C), acetate (2-14C) and DL-tryptophan (3-14C) was shown to be radioactive. Degradation of the labeled skimmianine showed that the radioactivity was located in the benzene ring when anthranilic acid (T) was administered, while it was located at the position 3 of quinoline nucleus when acetate (2-14C) or DL-tryptophan (3-14C) was used as the labeled precursors. On the basis of these results, a scheme of the biosythesis of skimmianine was proposed in which skimmianine was shown to be derived from anthranilic acid and acetate.
