title: The structure of a new crystalline cevane alkaloid: its identity with persicanidine B and harepermine.
abstract: The structure of a new crystalline base (melting point (mp) 167-169 degrees C) 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.
