Abstract

The invention provides an angelica dahurica extract including oxypeucedanin of 9.50-14.24mg / g. The invention further provides a medicine composite which is a medicine prepared from angelica dahurica extract as an active component and pharmaceutically acceptable auxiliary materials or auxiliary components. The invention further provides a method for detecting the quality of angelica dahurica crudedrug, the angelica dahurica extract or the medicine composite including the angelica dahurica extract by taking the oxypeucedanin as an index component. The contents of the oxypeucedanin and imperatorin are controlled, the qualities of the angelica dahurica crude drug and the angelica dahurica extract are detected, and the quality detection method can be applied to monitoring the quality of the crude drugs, and detecting and distinguishing whether the angelica dahurica is fumigated by sulfur or not; therefore, the invention can effectively monitor the quality of the angelica dahurica medicine; in addition, the medicine has clear effect and stronger controllability.
