INVESTIGATION OF ALCOHOL-WATER EXTRACTS OF GENISTELLA SAGITTALIS OBTAINED BY ULTRASONIC EXTRACTION

Abstract

Alcohol-water extracts of Genistella sagittalis have obtained by ultrasonic extraction method for different times extraction. The obtained extracts have been tested for the quantitative content of extractive substances, phenolic compounds and flavonoids and for the presence antioxidant activity. The best studied indicators were found in extract obtained by ultrasound extraction for 40 minutes (content of extractive substances 25 mg/ml, sum of polyphenolic compounds 30 mg/ml, flavonoids content 45 mg/ml).
