ABSTRACT
[Objective] To mensurate and compare with the mensuration of alkaloid and saponin in the flower,pedicel and bulb of fritillariae thuubergii,make full use of all parts of fritillariae thuubergi.i[Method]To mensurate the mensuration of alkaloid and saponin in the three parts of fritillariae with the twophase titration method and gravimetric method.[Result]The mensuration of alkaloid in the flowers of fritillariae thuubergii is 0.182%,while it is 0.047% and 0.341% in the pedicel and bulb separately,and the mensuration of saponin in the flowers of fritillariae thuubergii is 5.112%,while it is 8.840% and 1.724% in the pedicel and bulb separately.[Conclution] The difference of major component in the fritillariae thuubergii offers the foundation to make full use of the flowers,pedicel and bulb.
