Extending the range of medicinal products produced from plant raw materials and great interest in herbal medicine are totally linked to the availability of plant raw materials, minor toxicity and side effects. The use of medicinal plant raw materials as a source of valuable biologically active substances in the pharmaceutical and food industries is relevant.The aim of the study was to quantify and evaluate antioxidant activity of biologically active compounds (total phenols, anthocyanins) in the fruit and stem of elderflower (Sambucis nigra) and fruits of Caucasian bilberry (Vaccinium artostaphyion) wild-growing in Georgia.As raw material under study, we used wild-growing elderflower fruit with the fruit-bearing stem and bilberry fruits collected in August 2020 in the mountainous region of Georgia (Racha-Lechkhumi) in the phase of full ripeness.It has been confirmed that the elderflower’s fruit stems, as well as the fruit of elderflower anise and bilberry are rich in: phenolic compounds (elderflower’s fruit -13.8 mg/g, stem - 9.2 mg/g; bilberry fruit - 24.9 mg/g); anthocyanins (elderflower’s fruit - 1.4 mg / g, stem - 3.68 mg/g; bilberry fruit - 18.03 mg /g); they are characterized by high antioxidant activity (elderflower’s fruit - 48.2%, stem - 40.5%; bilberry fruit - 60.3%). Based on the results obtained, the fruits of bilberry and elderflower can be considered to be a cheap alternative source of natural antioxidants for the pharmaceutical, cosmetic and food industries.

The useful properties of medicinal plants are due to the presence of various biologically active substances in them, such as phenolic compounds, alkaloids, anthocyanins, glycosides, saponins, essential oils, resins, mucus, vitamins and so on, which have a certain effect on physiological processes in the human body. The object of the study was the the butcher’s broom fruit growing wildly in Georgia, collected in August-September upon full maturation. Our research confirms that the alcoholic extract of the butcher’s broom fruit contains biologically active substances (total phenols - 39 , 4 mg/g; anthocyanins - 39.4 mg/g), which leads to the high antioxidant activity of the said extract - 45% (F=10).

The nature of medicinal products of plant origin is determined by the content of various active components, which makes it possible to use them as therapeutic excipients in traditional medicine. The objects of the research were the roots and the ground part of butcher’s broom wild-growing in Georgia, in the active phase of vegetation: root - in November, the ground part (stem and leaves) in May. The 70% and 40% ethanol alcoholic extracts from root and herbs were prepared, 26.6 - 60.4 mg/g of total phenols were found in all four extracts; the content of flavonoids was 9.2 - 21.2 mg/g and the antioxidant activity was evaluated by the DPPH method at 24.3 - 68.2%.

The use of the natural plant components (fatty oils) and biologically active additives allows for balancing the formulation for cosmetic oils. When using biologically active supplements, the skin is rich in all the necessary nutrients that help to achieve the desired effect. When using biologically active additives, the skin is enriched with all the essential nutrients that help to achieve the desired effect. Research covered rosehip fruits wild-growing in western Georgia. To obtain extract from raw materials, we used the superfluid CO2 extraction method. We obtained oil with yield ranging from 8.12 to 10.17%, whose refractive index is 1,4782 units, and the extract rich in phenolic compounds, with total phenols -3032 mg/100 g and total flavonoids 1501 mg/100 g on dried basis.
