Abstract

The invention relates to an affective part of a vegetative medicine of Diangui blumea balsamifera and an extracting method thereof as well as a medicine composite containing the effective part of the Diangui blumea balsamifera. The method comprises the steps of: adopting big-pore resin to absorb, conducting ethanol grade washing and separation to obtain the total flavone extractive. The total flavone extractive of the Diangui blumea balsamifera is taken as the effective part to be solely used or used in the medicine composite for curing hemorrhage in gynae. The patient can conveniently take the medicine in small dosage reducing the per time dosage from 1g to 0.2g, moreover, the side effects are small and the curative effect is more distinct in addition that the quality is more stable. The invention is suitable for industrial production and has wide application prospect. The extraction rate of the total flavone extractive of the Diangui blumea balsamifera is 2 to 3 percent, and the content of the total flavone in the extractive is 50 to 60 percent. The products or the extractive of the invention can be made into troche, grain, oral liquid, pill, soft or hard capsule and other oral formulations by proper methods.
