Received Date: 24 February 1992

Fund Project: The work was supported by The National Natural Science Foundation of China Grant No. 28770103. We are also grateful to Analytical Department and NMR group of Phytochemistry Department for the measurement of all the spectra.

Four new alkaloids, didehydroprotostemonine, isoprotostemonine, neostemonine and stemodiol, were isolated from the roots of a Chinese medicinal plant, Stemona japonica, collected form Zhejiang Province, southern China. Their structures were elucidated by extensive spectral analyses.
