The analysis of gastrodin quantity from different variety sources under water extraction by high-performance liquid chromatography. Each value represents mean ± standard deviation (n = 3). The overall p value shown was obtained by analysis of variance Tukey’s test for multiple comparisons and indicated a significant difference (***p < 0.001) between Gastrodia elata Blume f. elata from Yun-nan (GRY) and G. elata Bl. f. glauca S. Chow from Yun-nan (GBY), and also between G. elata Bl. f. elata. from Hu-nan (GRH) and GBY.
