Abstract:
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.
