A spectrophotometric method of quantitative determination of total triterpenoid saponins in rhizomes and roots of Polemonium caeruleum is developed. The procedure does not require sandard samples. The standard relative error of determination does not exceed 4.88%. The proposed procedure is recommended for analysis of the raw material and ready-to-use medicinals based on Polemonium caeruleum. 456 0091-150X/08/4208-0456
