Method of quantitative determination of the
amount of anthocyanins in the raw materials of (Euterpe oleracea)
Abstract
The method of
quantitative determination of the amount of anthocyanins in Euterpe oleracea by
direct spectrophotometry is developed. The analytical maxima of the absorption
of anthocyanins in the fruits of Euterpe oleracea – 625 ± 2 nm (maximum) – were
determined. The optimal conditions for the extraction of anthocyanins from the
raw materials of this plant are justified (extractant – ethyl alcohol 40%; the
ratio of “raw material – extractant” – 1:100; extraction time – 60 minutes; the degree of grinding of raw materials 1.0 mm).
Key words:Euterpe oleracea, fruits,
pharmaceutical plant raw materials, anthocyanins, spectrophotometry,
cyanidin-3-O-glucoside.
