Abstract：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 Zh
