Summary
Anthranilic acid-(14COOH) was administered to rooted leaves ofAdhatoda vasica Nees. The isolated alkaloid peganine = vasicine was degraded according to the method ofSpäth andHikawitz (Figure). The anthranilic acid obtained showed the same specific radioactivity as the alkaloid. Therefore anthranilic acid must be regarded as a direct precursor of peganine inA. vasica Nees.
