从鄂北贝母ＦｒｉｔｉｌｌａｒｉａｅｂｅｉｅｎｓｉｓＧ．Ｄ．ＹｕｅｔＧ．Ｑ．Ｊｉ中分得４个生物碱单体，其中鄂贝定碱（ｅｂｅｉｅｄｉｎｅ）和去氢鄂贝定碱（ｅｂｅｉｅｃｉｎｏｎｅ）在该植物中首欢分得。经光谱等方法证明，文献［１］发表的新化合物鄂贝甲素（ｅｂｅｉｎｉｎｅ）和鄂贝乙素（ｅｂｅｉｎｏｎｅ）实与鄂贝定碱及去氢鄂贝定碱相同。
From Fritillariae beiensis Fritillariaeensis G. D. YuetG. Q. In Ji, 4 alkaloid monomers were obtained, of which ebeiedine and ebeiecinine were separated in the plant. The spectra and other methods proved that the novel compounds ebeiinine (ebeinine) and ebeinone (ebeinone) published in the literature [1] were identical to those of erbidentine and dehydroepimidine.
