QUALITATIVE AND QUANTITATIVE ANALYSIS OF FLAVONOIDS DURING DEVELOPMENT OF ANTIDIABETIC EXTRACT

Abstract

During development of antidiabetic extract in blueberry shoots (Vaccinium myrtillus L.), ginseng leaves (Panax ginseng C.A.Mey.) and water-alcohol extraction from this plant material the flavonoid content is studied because this group of biologically active substances has hypoglycemic effect. Qualitative reactions for different groups of flavonoids has confirmed their presence in blueberry shoots and ginseng leaves. In addition, qualitative analysis of water-alcohol extraction on their base using spectrophotometry has also showed presence of this group of biologically active substances. Along with that, quantitative content of flavonoids has been detected using differential spectrophotometry in blueberry shoots, ginseng leaves and water-alcohol extraction on their base.
