Optimization of Percolation Extraction Conditions of Sanguisorba Tannins
摘要
Abstract
[Objective] To optimize the extraction conditions of Sanguisorba tannins. [Method] With the content of Sanguisorba tannins and the yield of dry paste tannin extracts as the major evaluation indexes and the garlic acid as the control, the content of Sanguisorba tannins was determined by the UV-Vis spectrophntometry and the factors of particle size, solvent dose, percolation rate and diameter-height ratio were optimized. [Result] The RADIX SANGUISORBAE was pulverized and passed through the No. 1 sieve, and then put into a percolation barrel with 1:1 of diameter-height ratio, and extracted at the solid-liquid ratio of 1:6 (g/ml), 70% ethanol concentration and 5 ml/ min ?kg rate. Under the opti1 mized conditions, the average yield of dry paste wab 30.48% and the extraction rate of tannins was 15. 5%. [ Conclusion] The extraction technology is reasonable and practical with good reproducibilily and high extraction rate, thus it can provide basis for the production of semi-finished products of Sanguisorba tannins.关键词
