In the reinvestigation of the constituents of Uncaria rhynchophylla MIQ. (Japanese name "kagikazura"), the presence of two oxindole alkaloids, corynoxeine and isocorynoxeine, was demonstrated, besides the reported rhynchophylline and isorhynchophylline.^<3)> Furthermore, four indole alkaloids were newly isolated ; hirsutine, hirsuteine, dihydrocorynantheine, and corynantheine. A chemical structural evidence of hirsutine was obtained from its epimerization to dihydrocorynantheine with acetic acid catalysis.
