摘要
目的:测定黎川岩泉自然保护区中薯莨的总鞣质和缩合鞣质含量。方法:采用《中国药典》(2010年版)比色法测定总鞣质,采用香草醛硫酸法测定缩合鞣质。结果:薯莨中总鞣质与缩合鞣质平均质量分数分别为(501.81±8.62)mg·g-1,(421.78±11.65)mg·g-1。结论:薯莨鞣质含量高,鞣质类型主要为缩合鞣质,具有良好的开发前景。
Objective： To establish the quantitative assay of total tannins and condensed tannins in Dioscorea cirrhosa Lour. from the Lichuan Yanquan Nature Reserve of Jiangxi province. Methods： The colorimetry in Chinese Pharmacopoeia （2010） was used for the determination of total tannins content. The Vanillin-H2SO4 method was employed for the determination of condensed tannins content. Results： The content of total tannins and condensed tannins were （ 501.81 ± 8.62 ）mg·g^-1 and （ 421.78 ±11.65 ） mg·g^-1 respectively. Conclusion： Wild Dioscorea cirrhosa Lour. collected from the Lichuan Yanquan Nature Reserve of Jiangxi province, contained high content tannins which was mainly condensed tannin. This implies Dioscorea cirrhosa Lour. has a good exploration prospect.
