Objective: To determine the total polyphenol content in the fibrous roots and tubers of Rhizoma Bletillae Striatae. Method: The content of total polyphenol in the fibrous roots and tubers of Rhizoma Bletillae Striatae was detected by folin colorimetry method using gallic acid as index
then using TLC method to qualitative compare fibrous roots with tubers of Rhizoma Bletillae Striatae. Result: There was a good linearity in the range of 5-25 μg for the gallic acid
the standard curve equation was Y=0.033 2X+0.000 1. The total polyphenol content in the fibrous roots was 0.895% while tubers was 0.394%. Conclusion: the total Polyphenol content in the fibrous roots of Rhizoma Bletillae Striatae is higher then tuber.
