Introduction. Recently, much attention has been paid to the primary assessment of the pharmacological effect of various drugs using in vivo and in vitro tests. It is known that such a medicinal plant as sea buckthorn, in its phytochemical composition is rich in natural antioxidants: carotenoids, tocopherols, flavonoids, ascorbic acid, etc. In some publications there is information about the antioxidant activity of sea buckthorn and fatty oil based on them. However, information on the comparative characteristics of the use of various methods for determining the antioxidant activity of this type of medicinal plant material and the results obtained are not found in the scientific literature.Aim. The aim of this work was a comparative determination of the antioxidant activity of medicinal plant material of buckthorn fruits of various species of buckthorn.Materials and methods. The total antioxidant activity of water and water-alcohol extracts from the fruits of sea buckthorn fruits was determined using various techniques recommended in the literature. The antioxidant activity of the extracts was determined by permanganometric titration, in vitro inhibition of adrenaline autooxidation, and also in a biological model, Parametium caudatum cell culture.Results and discussion. The effect of the extractant polarity on the value of antioxidant activity was studied. It was found that the highest content of antioxidants in the extraction is observed when using 96 % ethanol as an extractant.Conclusion. Using three methods, the prospects of using sea buckthorn fruits and preparations based on them as a source of antioxidants are shown.

Aim. To investigate the content of heavy metals in the seeds of milk thistle (Silybum marianum (L.) Gaertn.) and in the product of its processing – oil. To reveal possible changes in the concentration of heavy metals in the years of cultivating this plant. Methods. The fi eld and spectrometric methods were applied; the results were processed using the technologies, common for agriculture, plant production and statistics. Results. The content of heavy metals in the seeds of milk thistle was defi ned. It was determined that their concentration exceeds maximal acceptable coeffi cient for the medicinal plant material. It was established that in 2013 the seeds of milk thistle accumulated several times more Ba, Ca, Fe, Mg, Mo, Sr, V compared to the indices of 2014, while Al, Co, Ag were found only in the samples of the seeds, harvested in 2013. Conclusions. As the regulatory documents regarding many relevant elements, which belong to heavy metals, do not specify maximal accept- able coeffi cients for the content of the latter in the medicinal plant material, it is reasonable to conduct complex studies, involving the specialists of relevant fi elds, in order to stipulate this gradation. In the Kyiv region the milk thistle plants accumulate a large amount of such heavy metals as cadmium, manganese, strontium, and zinc, which exceeds maximal acceptable degrees of accumulation and testifi es to partial pollution of region soils. It was established that the concentration of the main part of heavy metals in the product of processing milk thistle – oil – is decreased to the value under the threshold of analytic devices. This fact proves the pros- pects of growing milk thistle for industrial processing purposes.
