[HPLC analysis of alkaloids in Sophora flavescens Ait].

Only registered users can translate articles

In this paper, a HPLC method was developed for the determination of alkaloids in Sophora flavescens Ait. Experimental evidences indicate that a system of a LiChrosorb-NH2 column (4.0 mm x 250 mm) as stationary phase and CH3CN--H3PO4(pH2)--CH3CH2OH(80:8:10) as mobile phase can separate the five

Determination of quinolizidine alkaloids in Sophora flavescens and its preparation using capillary electrophoresis.

A simple and accurate capillary electrophoresis method was developed for the determination of four quinolizidine alkaloids in Sophora flavescens and Kuhuang injection. Optimum separation of the analytes was obtained on a 65 cm x 75 microm i.d. uncoated fused-silica capillary using a aqueous buffer

[Study on quality standard of Sophora flavescens root extract].

Only registered users can translate articles

As a part of the project for the Chinese Pharmacopoeia (2015 edition), the quality standard of Sophora flavescens root extract was investigated and established. According to the methods described in the Appendix of Chinese Pharmacopoeia (2010 edition), the water and ash inspections were carried out.
