Compare of extraction of phenolic compounds from Pistacia atlantica in different solvents

摘要

Determination and extractive efficiency of phenolic compounds from plant material is greatly depended on the solvent. In this research, methanol and ethanol were used for taking out the phenols from Pistacia atlantica. The total phenolics and some individual phenolics, such as gallic, chlorogenic, ellagic, sinapic and protocatechuic acid, (+)-cateehin and juglone were detected. Total phenolic contents were determined spectrofotometric but individual phenols using HPLC. Amounts of total phenolics were higher when for extraction methanol was used compare to ethanol. Similar effect of the solvents was observed in the case some individual phenols, such as jug lone, (+)-catechin, gallic, protocatechuic and chlorogenic acid. On the contrary, for ellagic and sinapic acid the extraction was better when ethanol was used compare to methanol.
