【Abstract】 The color is Objective: To study the influence of decocting time on dissolution of ferulic acid indecoctions of Radix Angelicae Sinensis. Methods: HPLC method was used for detecting the content of ferulic acid in Radix Angelica Sinensis decoction. Results: Dissolution of ferulic acid was the highest when the herb was decocted for 2.5 h(90 min, 60 min),then its content was decreased the extended decocting time. Conclusion: The appropriate decocting method of Radix Angelica Sinensis is decocted for 90 min first and then decocted for 60 min.更多还原
