摘要
目的建立青钱柳中三萜成分含量的测定方法。方法采用香草醛-冰醋酸、高氯酸显色法,于560nm处测定吸光度。结果方法的线性范围为4~24μg/mL,r=0.9992,平均回收率为98.52%,样品中三萜成分含量为0.586%。结论方法简便,快速,结果准确,可靠,适合三萜成分的含量测定。
OBJECTIVE To establish a simple and accurate method for the determination of triterpene in cyclocarya paliurus (Batal.) Iljinskaja. METHODS The UV speetrophotometry was used to determine triterpene in cyclocarya paliurus (Batal.) Iljinskaja at 560nm. RESULTS The content of triterpene in cyclocarya paliurus (Batal.) Iljinskaja was 0.586%, the linear range of the method was 4~24μmL(r = 0.999 2). The average recovery was 98.52%. CONCLUSION The method was simple, rapid, reliable and accurate.
