Abstract:
Investigation of the leaves of Cryptocarya chinensis resulted in the isolation of three new alkaloids, named (-)-isocaryachine-N-oxide, isoboldine-beta-N-oxide, and 1-hydroxycryprochine, together with seven known compounds. Their structures were elucidated by spectral analysis. The structures of (-)-isocaryachine-N-oxide and 1-hydroxycryprochine were further confirmed by X-ray techniques.
