摘要
目的测定土茯苓中单宁的含量。方法以单宁分析纯为标准,用火焰原子吸收法测土茯苓中单宁的含量。结果土茯苓中含量为(16.06±0.18)mg/g(n=4),回收率为98.2%,RSD为3.9%(n=4)。结论土茯苓因其单宁含量丰富而具有重要的药用价值。
OBJECTIVE To determine the content of dannin in Smilax Glabra. MTHODS The content of Dannin in Smilax Glabra was determined by indirect atomic absorption spectrometry. RESULTS The-average content was 16.06 ± 0.18mg/g. The average recovery was 98.2% and RSD was 3.9% （ n = 4）. CONCLUSION Smilax Glabra is of great medicinal value because of the rich dannin.
