The structure of a new crystalline base ( melting point (mp) 167 - 169 degreesC) obtained from Fritillaria imperialis was elucidated as (20R, 25R)- 5alpha, 17beta-cevanine- 3beta,6beta-diol, X-ray diffraction analysis of the mono-hydrate. The base was found to be identical with persicanidine B and also with harepermine.
