Summary

Determination of Strychnine and Brucine by HPLC for Better Quality Control of Strychni semen

In the 5th Vietnamese pharmacopoeial monograph for Strychni semen, 19 species of the genus Strychnos are accepted as medicinal material, and the quality of Strychni semen varies significantly. In this study, a high-performance liquid chromatographic (HPLC) method is used to identify and quantify strychnine and brucine in 12 Strychni semen samples collected from different regions in Vietnam and Laos. Based on the alkaloid content in combination with the morphological properties of the analyzed samples, some comments on measures to improve quality control of Strychni semen were suggested for the Vietnam market.

Keywords: Strychnine, Brucine, Strychni semen, HPLC, Quality control.
