摘要
目的对不同产地的楮实子生物碱含量进行比较研究。方法采用酸性醇回流法提取了楮实中的总生物碱,依照酸性染料比色法的原理,在410 nm波长下测定生物碱的含量。结果取得良好的线性关系(r=0.999 5)和回收率(98.52%),RSD为0.91%。不同产地的楮实子药材中所含生物碱的含量为7.98 mg/g至23.53 mg/g不等。结论楮实子生物碱含量显示出明显的地域性差异。
Objective To compare the total alkaloids content of Fructus Broussonetiae from different habitats.Methods Total alkaloids were isolated by acid-ethanol and determined by acid dye colorimetry method under 410nm.Results The calibration cure of alkaloids was linear（r=0.999 5）,the recovery rate was 98.52% and RSD was 0.91%.The total alkaloids content of Fructus Broussonetia from different habitats was 7.98～23.53 mg/g.Conclusion The total alkaloids content of Fructus Broussonetiae from different habitats was significantly different.
