title: [Simultaneous determination of brucine and strychnine in semen Strychni by dual wavelength spectrophotometry and studies on processing principles of semen Strychni].
abstract: The paper reports the experimental result of the simultaneous quantitative determination of strychnine (ST) and brucine(BR) in Semen Strychni by dual wavelength spectrophotometry. The result shows that there are some deviations in the official method, because the wavelength combination might not have been chosen rightly and the correct coefficient is inconsistent with the facts. We have made a study of the thermal stability of ST and BR, too. On this basis a baking principle for Semen strychni is spelt out.
