概要
Eight alkaloids were isolated from the bulb of Fritillaria Wabuensis S.Y. Tang et S.C. Yueh the best "Chuan Bei" cultivated in Sichuan province, which is efficacious against cough. Five of them are known, identified as imperialine (I), peimisine (II), ebeinone (III), isoverticine (IV), and imperialine-beta-N-oxide (V). All the signals for both 1H and 12C-NMR spectra of base (V) were assigned by 2D NMR experiments, and an X-ray structural data of alkaloid (V) was obtained for the first time.
