[Quality control of Angelica sinensis with standard reference extract]

To improve the quality standard of Angelica sinensis, solve the problem of lacking relevant reference substance, a new method-based on the standard reference extract (SRE) was applied to achieve the quality control of Angelica sinensis. SRE of Angelica sinensis was obtained by chromatographic separation technology. After calibration of three makers of the SRE, an UPLC analytical method was developed to determinate the contents of the makers. T-test was used for comparison of the determination results of two methods (reference substances and SRE as reference, respectively), and the results demonstrated that there is no significant difference between the two methods. The presented method is very convenient and practical, which can be used for the quality control of Angelica sinensis.
