Multiple gradient development (MGD) of (ferulic, caffeic, chlorogenic, protocatechuic, p-coumaric, o-coumaric, m-coumaric, syringic, synapic, p-hydroxybenzoic, gallic, elagic, isochlorogenic acid) in plants on silica gel, amino, cyano, RP18W and diol plates with mobile phases of variant range of polarity. This method is useful for the analysis of plant extracts rich in many substances of wide polarity range.
