Currently available on the pharmaceutical market drugs do not fully have high antioxidant activity, so the search for new means to prevent and eliminate liver damage is relevant. The purpose of this study was to evaluate the use of vyazolistnogo labaznik to increase the antioxidant activity of hepatoprotective collections of plant origin. Water extracts of hepatoprotective collection (GPS) have significant antioxidant activity, which is reflected by its linear dependence on the amount of GPS taken for extraction with a confidence value of approximation R2 of 0.989. Total antioxidant activity (TAA) the collection infusion increased from 0.690 to 4.883 g of rutin (Ru) per 1 dm3 when brewing from 5 g to 40 g of collection per 1 liter of boiling water, while the linear dependence twice reaches the plateau when the amount of collection taken for extraction is 10-12 g and 18-21 g, the TAA of GPS infusions was 1.35±0.004 and 2.26±0.11 g of Ru per 1 dm3. To increase the TAA of the water extract of GPS, an aqueous extract of dried flowers of elmberry (Filipendula ulmaria (L.) Maxim) was used, obtained in a similar way. The TAA of water extracts of GPS as the labasnik extract was added increased to its content of 30 % wt., and the effects of synergy (TAAexcess) – decreased to 0 (labasnik content of 35 % wt.), passing into antagonism according to the linear equation with a confidence value of approximation R2 0.981. Comparative tests of water extracts of laburnum flowers and GPS in closed containers for storing biological samples at a temperature of +5 °C in the refrigerator showed that the TAA of water extraction of laburnum flowers in g Ru by 1 dm3 from the number of days of its aging decreases according to the linear equation with the approximation confidence value R2 0.927, and GPS increases – R2 0.965.

The article presents the results of biochemical studies of the total antioxidant activity of the hepatoprotective collection of plant origin and its individual components, which show that it consists of birch leaves (Betulae folia), tansy flowers (Tanaceti flores), phytohepatol No. 2 (choleretic collection No. 2) and individual its components have pronounced antioxidant activity. More antioxidant activity founded in tansy and true hepatoprotective collection. Comparative tests of the flowers of meadowsweet, with the highest antioxidant activity, showed the promise of their use in the collections of medicinal plants as effective natural metabolic regulators. The total antioxidant activity of the water extract collection at 13.56% rel. exceeded the calculated value obtained by summing the activities of the individual components of the collection, which indicates the presence of synergism in their action, which may be of value for use in the treatment and prevention of liver diseases. When all components of the drug collection are finished, the indicator increases by 11-24 % rel., which indicates the thermal stability of the antioxidant substances that make up their composition. In the oxidation of aqueous extracts of the components of hepatoprotective collection with hydrogen peroxide, the most stable were antioxidants of birch leaves. It was found that collection only at a ratio of 7.7 g per liter of water shows synergism (15 % rel.), and the rest of all the samples we tested are antagonistic. The detected increase in the antioxidant activity of the new collection compared with the effects of its individual components allows us to consider it as a promising dosage form for use in the treatment and prevention of liver diseases.

Antioxidant compounds play a significant role in preventing and scavenging free-radicals by reducing oxidative stress and providing protection to humans against degenerative diseases and infections. Obviously, antioxidant molecules of plant origin are pivotal to combat the oxidative harm in cells. Present work intended to evaluate the antioxidant capacity of the fruits of Spondias pinnata. Methanol extracts of the fruits at two stages of maturity were prepared and investigated by various antioxidants analyses such as total antioxidant activity, reducing power and radical scavenging assays (DPPH, nitric oxide and hydrogen peroxide). Its total phenol, flavonoid and tannin contents were also determined. Spondias pinnata fruit extracts exhibited effective antioxidant activity and its IC50 values of the unripe fruits were 65, 66, 72.23, 83.25, 66.75 ?g/ml and ripe fruits were 124.24, 92.50, 97.66, 144.10, 72.25 ?g/ml, for total antioxidant activity, reducing power, DPPH radical scavenging, nitric oxide radical scavenging and hydrogen peroxide scavenging assays respectively. The extracts, especially unripe fruit extract had good amounts of total phenolic and flavonoid contents which might contribute the antioxidant activities considerably. It is evident from the study that the fruits of S. pinnata possessed potent antioxidant activity and it can be considered as a good dietary choice among the underutilized fruits as well as common fruits. Therefore, wild mango may be a good choice of antioxidants of plant origin for dietary and pharmaceutical uses.

A biologically active extract from the darkling beetle Ulomoides dermestoides was obtained using the electro-pulse plasma dynamic extraction method. The beetle water extract contained a complex of antioxidant substances such as antioxidant enzymes and nonprotein antioxidants, as well as a complex of heat shock antistress proteins. This determines the rather high antioxidant activity of the aqueous extract of the beetle, i.e., 1 mg of dry matter/mL of the extract has an equivalent antioxidant activity to 0.2 mM Trolox (a water-soluble analog of vitamin E). It was shown that the beetle extract can lead to a 25–30% increase in the average lifespan of nematode Caenorhabditiselegans, under normal conditions, and a 12–17% increase under conditions of oxidative stress (with paraquat), and significantly inhibits the fructosylation reaction of serum albumin. Therefore, the beetle aqueous extract shows promise as a biologically active complex exhibiting antioxidant activity.
