A. Kowalczyk et al., Thin-layer chromatography and densitometry of caffeic acid in some Dipsacaceae family plants, J PL CHROM, 14(3), 2001, pp. 175-177
Gradient thin-layer chromatography and densitometry have been used for qual
itative and quantitative analysis of caffeic acid in some Dipsacaceae famil
y plants. The presence of caffeic acid was determined in complex plant extr
acts before and after acid hydrolysis.
