Two new steroidal alkaloids from bulbs of Fritillaria lichuanensis.
Two new steroidal alkaloids, lichuanine (1) and lichuanisinine (2), were isolated from the bulbs of FritillariaLichuanensis P. Li et C.P. Yang. Their structures were determined to be (20S,25R)-5alpha, 14alpha-cevanine-3beta, 6beta-diol (1) and (20S,25S)-5alpha,14alpha-cevanine-3beta,6beta-diol-N-oxide (2) by means of spectral analysis and chemical evidence.
