Abstract:In our previous papers, it was reported that peimine, peiminine, eduardine and three new alkaloids, zhebeinine, zhebeirine, zhebeinone, were isolated from the bulbs of Fritillaria thunbergii Miq. In consecutive investigation of the plant, an additional new alkaloidal glucoside, 5α , 14α -cevanine-6α , 20β-dihydroxyl-3β-O-β-D-glucoside, named zhebeininoside (Ⅰ) and aknown picropodophyllotoxin (Ⅱ) were isolated. The structure of zhebeininoside was determined on the basis of spectral analysis and chemical reaction. Picropodophyllotoxin was firstly isolated from Fritillaria plants.
