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