Method for the quantitative determination of vincamajine in the herbVinca major introduced into Georgia

Stability-indicating methods for determination of vincamine in presence of its degradation product

“…The concentration of vincamine has been measured in blood plasma densitometrically using a solvent system composed of chloroform-methanol (9:1, v/v) and silica gel plates [14]. Spectrophotometric determination of vincamine in vinca major extract after separation on TLC silica gel LS 5/40 plates using benzene-ethyl acetate-methanol (1:1:1, v/v/v) as a developing system has been reported [15].…”
