[The relationship between inhibitory effect of xuanfuguilian prescription on the growth of esophageal cells ECA9706 and its components].

Objective: To discuss the relationship between inhibitory effect of different concentration ethanol extracts from Xuanfuguilian prescription on the growth of esophageal cells ECA9706 and its components.

Methods: The drug was extracted with anhydrous ethanol, 95%, 85%, 75%, 50%, 25% ethanol or water, the cell proliferation inhibitory rate of different solvent extracts were detected with MTT assay, and IC50 was calculated. The components of the drug were determined by LC/MS.
