Abstract
The present study was performed to report the quantification of myricetin present in different extracts (i.e. ethanol, methanol, petroleum ether, chloroform and aqueous extract) of root, leaf, bark, stem and seed of Myrica esculenta using TLC densitometric method. Densitometric scanning was performed at 366 nm for the determination and quantitation of standard compounds. The compact spots were achieved at Rf 0.67 corresponding to myricetin. The content of myricetin present in different solvent extracts of M. esculenta was 0.2159 ± 0.002% w/w, 0.3139 ± 0.003% w/w, 0.0184 ± 0.004% w/w, 0.0139 ± 0.003% w/w and 0.2120 ± 0.005% w/w in ethanolic, methanolic, petroleum ether, chloroform and aqueous extract of M. esculenta stem, stem, bark, leaf and leaf plant parts, respectively. The highest myricetin content was found in the order of methanolic stem extract>ethanolic stem extract>aqueous leaf extract>petroleum ether bark extract>chloroform leaf extract of M. esculenta. The developed HPTLC method was a precise, simple, convenient and accurate for screening of large number of active compounds present in various solvent extracts. Thus, the study concluded that the developed HPTLC method for quantification of myricetin can be used for a routine quality check and analysis of any formulation and composition containing M. esculenta.
