rats generally showed no significantly differences in parameters abnormalities of organ function, behavior and motor activity, blood biochemical parameters, hematology parameters, and did not produce mortality in treated groups compared to control group. Increasing dosage combination showed significantly increasing SGOT in male Wistar rats and MCHC in female Wistar

rats. The dried exctract combination also significantly decreased basophils in male Wistar rats and eosinophils in female Wistar rats.

Based on the finding of this study, the no-observed-adverse-effect-level (NOAEL) of dried extract combination in Wistar rats, following oral administration for 28 days was found to be more than 1000 mg/kg bw.

The advantages of herbal medicines in comparison with synthetic analogues are mainly in the complex effect and the possibility of long-term use without significant side effects. In addition, some medicines that are especially valuable for medicine are still receive only from plants (cardiac glycosides, strychnine, photosensitizing drugs).

The purpose of this work is to conduct phytochemical analysis and isolation of individual substances from the grass of Solidago canadensis L. The known diuretic, anti-inflammatory and antibacterial activity of the summary extracts of Solidago canadensis gives the possibility of the creation of a new medicinal drug for urological practice [1, 2].

In the course of the work, the following tasks are planned: harvesting the target plant raw materials and obtaining total extracts, isolating the individual substances from the total extracts, establishing and confirming the structure of the individual compounds and preparative isolation of the targeted individual substances.

At the moment, harvesting and grinding of the Solidago canadensis grass has been carried out, the optimal solvents for vacuum chromatography (methanol) have been selected, and total extractions

have been obtained. Preliminary tests were carried out: paper chromatography in 2 solvent systems: 15% acetic acid and BAW (buthanol-1, acetic acid and water) -(4: 1: 2), and TLC analysis in BAW and dichloromethane-methanol systems (5: 1). According to the obtained data, substances that give fluorescence in UV radiation were found in the analyzed fractions. The chemical structure of substances will be determined.

Also, HPLC analysis of these fractions was carried out. Four fractions were obtained from the ethanol extract of the Solidago canadensis: hexanoic, dichloromethane, ethyl acetate, and methanol. According to the data obtained the most promising from the point of view of the isolation of individual flavonoids is the methanol fraction. In the methanol fraction there are 5 compounds belonging to the class of flavonoids. In the future, it is planned to separate and preparatively isolate these substances.

Schisandra chinensis (Turcz.) Baill. - Chinese magnolia vine it's pharmacopoeial plant species also in Europe with well-established pharmaceutical activity. Schisandrae chinensis fructus, shows adaptogenic, hepatoprotective, antioxidant and anticancer activity. Biological activity of the plant is attributed mostly to dibenzocyclooctadiene lignans, called the schisandra lignans [1]. Shoot-differentiating callus cultures of

S. chinensis established in our laboratory were capable of accumulation of high amounts of lignans [2, 3]. The aim of the present study was to investigate the accumulation of these compounds in in vitro cultures of Ukrainian cultivar - S. chinensis cv. Sadova No. 1.

Agar microshoot cultures were maintained on six variants of Murashige and Skoog (MS) medium [4], differing in concentrations of the plant growth regulators
