Results Bulbus alkaloids easily formed molecular ions(superscript + in MS and dimerized easily in alcohol solution, which did not dimerize in acidity solution. Collision induced dissociation made these alkaloids easily lose a molecule of H2O. The MS spectra of the extracts of five Bulbu Fritillartae species indicated that the major molecular ions were similar to each other, but different varieties showed very different relative abundances of these molecular ions.

结果 在正离子一级质谱中，贝母生物碱易形成带一个正电荷的准分子离子，并且在中性醇溶液中，贝母生物碱易形成二聚体，在酸性介质中则无此现象；二级碰撞诱导解离易使贝母生物碱脱去一分子水；5种贝母对照药材的总生物碱提取液的一级电喷雾质谱图显示，主要分子离子峰基本相同，但因品种不同相对丰度差异较大。
