QUALITATIVE AND QUANTITATIVE ANALYSIS OF FLAVONOIDS DURING DEVELOPMENT OF ANTIDIABETIC EXTRACT

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.

Obtaining an antioxidant complex of bas extracted from Thymus Vulgaris L. and Panax Ginseng S.A. Meu

The article presents a chromatographic study of a complex of BAS obtained by water-alcohol extraction of medicinal plants of the Siberian Federal District. Medicinal plants Thymus vulgaris D. and Panax ginseng S.A. Menu were selected as BAS analysis

STUDY OF OUTWARD SIGNS, MICROSCOPY AND CHEMICAL COMPOSITION OF WALNUT

Objective: Walnut is a medicinal plant that is widely used in traditional medicine. We believe that the study of the medicinal plant material of walnut-fruit in the stage of milky-wax maturity and walnut bark is relevant. We described outward signs and microscopy, the diagnostic features of both whole and grinded raw materials, powder bark of walnut and fruits of walnut in the stage of milky-wax maturity.Methods: Alcohol extraction which was derived from walnut bark is a transparent liquid of brown color and alcohol extraction which was derived walnut fruits in the stage of milky-waxy maturity is a transparent, green-brown liquid with a fragrant smell. We performed thin-layer chromatography for the walnut cortex and identified gallic acid.Results: A method of chromatography-mass spectrometry in alcohol extraction from walnut fruit in the stage of milky-waxy maturity allowed to identify 17 compounds belonging to different classes of biologically active substances. We identified sugars, flavonoids, phenolic compounds of coumarins and organic acids. In alcohol extraction from the walnut bark we identified marker substances.
