| Abstract: | Objective ] Total phenols in three different habitats＇ Gastrodia elsta B1. f. elata, were determinated. Method ] The content of to- tal polyphenol was detected by Folin-Ciocaileu Colorimetry using gallic acid as index. Result] The total polyphenol content in three different habitats＇ Gastrodia elsta B1. f. elata, displayed remarkable difference. Among them, the content of Hubei Yichang Gastrodia elsta B1. f. elata. was the highest（0.048 5% ）. Conclusion] The method is convenient, rapid, and exact to determine the total phenols in Gastrodia elsta B1. |
