Abstract
Objective To establish the method for determination of total polysaccharide in Ruoshiming Mixture by UV - spectrophotometry. Methods The total polysaccharide in Ruoshiming Mixture was tested at the wavelength of 490 nm with UV - spectrophotometry by using glucose as standard substance. Results The regression equation was A = 15. 571 X + 0. 026v r = 0. 999 8 ). The linear range of glucose was 0. 008 08 - 0. 048 48 g/L( r = 0. 999 8, n = 5 ). The average recovery was 99. 51% , RSD was 1. 26% ( n = 6 ). Conclusion The method is simple, accurate, reproducible and is suitable for content determination of Ruoshiming Mixture.关键词
