中文摘要：

目的：对新疆贝母属8种药用贝母地上茎、叶与地下鳞茎部位总生物碱含量进行对比研究。方法：采用酸性染料比色法测定总生物碱的含量。结果：新疆贝母属8种药用贝母不同部位生物碱含量由高到低的顺序为：叶〉鳞茎〉茎;新疆贝母属8种药用贝母总生物碱含量由高到低的顺序为：伊犁贝母〉裕民贝母〉新疆贝母〉黄花贝母〉托里贝母〉大白花贝母〉滩贝母〉小花贝母;地上部位中总生物碱含量为地下鳞茎中的1.174~1.499倍。结论：新疆贝母属8种药用贝母植株中总生物碱含量因品种及部位不同而存在差异,但总体上地上茎叶的总生物碱含量高于地下鳞茎,存在进一步研究与开发的价值。

英文摘要：

Object： To measure and compare the content of total alkaloid in the stem, leaves and bulb of eight medicinal plants of Fritillaria L. from Xinjiang. Methods： Acid dye colorimetric methods were used to investigate the content of total alkaloid. Results ： The content of alkaloids in difference parts from higher to lower ： leaf 〉 bulb 〉 stem ; the content of total alkaloids in difference species from higher to lower： F. pallidiflora 〉 F. yuminensis 〉 F. walujewii 〉 F. verticillata 〉 F. tortifolia 〉 F. verticiUata var. albidoflora 〉 F. karelinii 〉 F. meleagroides ; the content of total alkaloids in aerial parts were 1. 174 - 1. 499 times more than underground parts. Conclusion： The content of total al- kaloids with different species and parts is different, but in general the content of total alkaloids of stems and leaves of aerial parts were significantly higher than the bulbs, so the former deserves to be further developed and utilized.
