Study on effects of sweating treatment and different drying methods on the quality of Gentianae macrophyllae Radix

Abstract To provide basis for improving the quality of Gentianae macrophyllae Radix and optimising the field processing method. Gentianae macrophyllae Radix samples were collected from Long County. Five main active iridoids were determined by using HPLC. The HPLC fingerprints were measured and analy...
