目的: 建立蒙药复方述达格-4 中总内酯的含量测定方法。方法: 以异土木香内酯为对照品,以盐
酸、三氯化铁为显色剂,采用紫外可见分光光度法测定述达格-4 中总内酯的含量。结果: 异土木香内酯在0.842
~ 5.052mg 范围内与吸光度呈良好的线性关系Y = 0.1493X+0.1399( r = 0.9995) ,平均加样回收率为98.43%,RSD
= 1.69%( n= 6) 。结论: 该方法简便、灵敏、准确,可用于述达格-4 中总内酯含量的测定。

Objective: To establish the method for the content determination of total lactone from
Mongolian Medicine Shudage-4.Methods: Hydrochloric acid,Ferric chloride solution was used as color
developing agent.UV-Vis spectrophotometry was established for the content determination of total lactone
from Mongolian Medicine Shudage - 4.Results: The linear range of isoalantolactone was 0.842 ~
5.052mg,Y= 0.1493X+0.1399( r = 0.9995) with an average recovery of 98.43%( RSD = 1.69%,n = 6) .
Conclusion: This method is simple, sensitive and accurate,and it is suitable for the content determination
of total lactone from Mongolian Medicine Shudage-4.
