HPLC-ELSD法测定麦冬药材及其提取物中果糖的含量

Determination of Fructose in Radix Ophiopogonis and Extracts of Radix Ophiopogonis by HPLC-ELSD

目的测定不同产地的川麦冬、浙麦冬药材及麦冬提取物中果糖的含量,为麦冬药材及其提取物的质量控制提供科学依据。方法采用HPLC-ELSD法测定麦冬药材及提取物中果糖的含量。结果川麦冬和浙麦冬药材中果糖的含量分别为11.32%～19.96%、3.85%～10.19%,川麦冬和浙麦冬提取物中果糖的含量分别为23.48%～25.82%、21.39%～23.29%。结论川麦冬药材中果糖的含量明显高于浙麦冬药材,川麦冬提取物中果糖含量与浙麦冬提取物基本一致。

Objective To determine the content of fructose in radix ophiopogonis cropped in Sichuan and Zhejian, and in extracts of radix ophiopogonis. Methods A HPLC-ELSD method was used for determining the content of fructose. Results The content of fructose in radix ophiopogonis cropped in Sichuan and Zhejiang were 11.32%-19.96% and 3.85%-10.19%, respectively. The contents of fructose in extracts of radix ophiopogonis cropped in Sichuan and Zhejiang were 23.48% - 25.82% and 21.39% -23.29%, respectively. Conclusion The content of fructose in radix ophiopogonis cropped in Sichuan was higher than that of in Zhejiang. The content of fructose in extracts of radix ophiopogonis cropped in Sichuan was almost the same as that of in Zhejiang.
