Lg. Song et al., STUDIES OF CRUDE CHLOROFORM EXTRACT OF ROOTS OF PODOPHYLLUM-EMODDII VAR CHINESIS SPRAGUE BY MICELLAR ELECTROKINETIC CHROMATOGRAPHY, Chromatographia, 39(11-12), 1994, pp. 682-686
A crude chloroform extract of the roots of Podophyllum emoddii var. ch
inesis Sprague was studied by micellar electrokinetic chromatography.
Four peaks belonging to podophyllotoxin, 4'-desmethyl-podophyllotoxin,
kaempferol and quercetin were identified by known standards. The four
substances are valuable pharmaceutical ingredients of the plant.
