| Abstract: | A evaluation method of uncertainty was tried to find out for determination of the total saponin in Radix Platycodonis by weight method. The determination of total saponin was carried out according to the method in volume one, Chinese Pharmacopoeia Edition 2005. A mathematics formula was established, the source of uncertainty was analyzed, and the combined uncertainty was calculated. The uncertainty of determination of total saponin in Radix Platycodonis by weight method was assessed, and the result of uncertainty was showed as 0. 2495P. |
