Studies on the Blue Luminescent Substance in the Berberine-containing Plants. IV

On the Blue Luminescent Substance from Berberis Thunbergii DC. var. Maximowizii Franch, and Berberis amurensis Rupr. var. japonica (Regel) Rehd. forma Bretschneideri

Abstract

From the acid ether-soluble portion of the extracts of the stems of Berbevis Thunbergii DC. var. Maximowizii Franch and of Berberis amurensis Rupr. var. japonica (Regel) Rehd. forma Bretschneideri (Rehd.) Ohwi, which contain berberine, ferulac acid, which exhibits blue fluorescence under ultraviolet light, and vanillinic acid, which does not show fluorescence, were detected by paper chromatography. There was a compound in the neutral portion of the latter plant which exhibited blue fluorescence.
