Qualitative and quantitative determination of protopine in Fumaria spp. by TLC-densitometry method
Article info: Received: 25 October 2012 Accepted: 21 December 2012 ABSTRACT A rapid and accurate TLC-densitometry method for qualitative and quantitative determination of protopine has been developed. The best separation was achieved using a mobile phase chloroform – ethyl acetate – methanol – ammonium hydroxide (80:80:40:0.05, v/v/v/v). The results obtained by this method (CV% 3.4) corresponde...
