“…Since partition chromatography (2) showed veratridine to be a major component of chloroform plates 0 through 7 and cevadine a major component of buffer plates 3 through 7, i t was possible to shorten the separation procedure by using a modified two-plate single-withdrawal countercurrent distribution. When this was done, using chloroform as the mobile phase and 0.5 M citrate buffer at PH 4.25 as the stationary phase, Fraction Sc, benzene soluble, was separated into three parts, namely, (A) material in the buffer plate 0; (B) buffer plates 1 and 2 ; and (C) material in the chloroform plates 0 through 7.…”
