The review summarizes data on biologically active compounds of Achillea nobilis L. and methods of their isolation. From Achillea nobilis L., collected in different places of growth, the following have been isolated: essential oil, the main components of which are monoterpene compounds; sesquiterpene lactones estafiatin, hanphyllin, anobin, chrysartemine A, canin, anolide and tanapartin-β-peroxide; the steroid acetyleucanbin; flavonoids: 3,5-dihydroxy-6,7,8-trimethoxyflavone, 5-hydroxy-3,6,7,4’-tetramethoxyflavone and 5,3’-di-hydroxy-3,6,7,4’-tetramethoxyflavone. It has been determined that the component composition of the essen-tial oil of Achillea nobilis L. largely depends on the soil and climatic factors in the places of its growth, the phase of the growing season and the method of its extraction from plant raw materials, and the extractant used (chloroform, ethanol, hot water, diethyl ether). Antibacterial, antimicrobial, antioxidant, antiparasitic activi-ties are characteristic both for the sums of extractive substances from Achillea nobilis L. and for individual compounds isolated from them. Methods for the isolation of biologically active substances from Achillea nobilis L. for the development of new drug substances are described. The main aim of this work was a com-parative analysis of the available research results on the phytochemical study of Achillea nobilis L.

The histochemical analysis of medicinal plants and raw materials makes it possible to establish the presence of certain groups of active and related substances or products of their metabolism, as well as to study their localization in tissues. The article presents the results of histochemical analysis of leaves, flowers, petioles and stems of Filipendula vulgaris and Filipendula ulmaria. These types of plant are used in traditional medicine as an anti-inflammatory, antipyretic and bactericidal agent. Our research objective - to determine the peculiarities of the localization features of individual groups of secondary metabolites in the aerial part of meadowsweet and meadowsweet growing in the territory of Central Kazakhstan at the microscopic level. Materials and Methods. Transverse sections of petioles, stem and whole flower; transverse and superficial sections of leaves of Filipendula vulgaris and Filipendula ulmaria were fixed in Strauss-Fleming solution, after which histochemical reactions were carried out to locate and identify essential oils, phenolic acids, flavonoids, sesquiterpene lactones, polysaccharides and alkaloids. The study of microscopic signs, as well as histochemical tests were carried out according to the methods of the State Pharmacopoeia of the Republic of Kazakhstan using a light microscope Biomed-4. Results and Discussion. The localization of biologically active substances in the studied types of plant raw materials was determined by histochemical methods using light microscopy. The presence of phenolic compounds, flavonoids, traces of essential oil, alkaloids and sesquiterpene lactones was established. The absence of polysaccharides in the investigated micropreparations was established. Conclusions. For the first time, the localization of secondary metabolites in the tissues of Filipendula vulgaris and Filipendula ulmaria was studied by histochemical tests. The results of histochemical studies can be used to confirm the authenticity, identification and standardization of the aerial parts of Filipendula vulgaris and Filipendula ulmaria.

Medicinal plants have bioactive compounds, which are used to treatments of various diseases. In the present study, Persicaria sagittata medicinal plant was used for the preliminary phytochemical screening. Methanol and petroleum ether were used as a solvent for obtaining the extraction of the plant. Both the extracts were further study for qualitative phytochemical screening using standard methods. Phytochemical screening shows that methanolic extract possesses the presence of tannins, flavonoids, and vitamin A as tannins and flavonoids are helpful for the uric acid stones. The study reveals that medicinal plant provides a basis of its use in medicine, improve to further drugs in the pharmaceutical area, and contains different biologically active constituents, and the secondary product is valuable of further analysis.

Abstract Saraca asoca (Leguminosae), (―)-Epicatechin, Procyanidin (B2), 1 1′-Deoxyprocyanidin B The bark of Saraca asoca is used as a main ingredient in the preparation of Asoka Arishta, a drug indigenous to Sri Lanka. In this paper an investigation on some biologically active constituents of the bark is described. (―)-Epicatechin and procyanidin B2 were identified and a new compound, named 11′-deoxy-procyanidin B, was found. Its structure was elucidated by means of proton-NMR.
