Spectrophotometric Method for the Quantitative Determination of Total Anthocyanins in Acerola (Malpighia emarginata) Raw Material
摘要
Abstract
A spectrophotometric method for quantitative determination of anthocyanins in Malpighia emarginata is developed. The analytical absorption maxima (534 ± 2 nm) of anthocyanins are determined. The optimal conditions for the extraction of anthocyanins from the raw materials of this plant are experimentally substantiated (extractant, ethyl alcohol 40%; raw material to extractant ratio 1 : 50; extraction time 30 min; raw material grinding degree 1.0 mm).
