ESSENTIAL OILS CONSTITUENTS OF POLYCOMPONENT HERB TEAS ACCORDING TO PRESCRIPTIONS OF TRADITIONAL TIBETAN MEDICINE, MANUFACTURED BY THE APHCI "RCHRT "CENTER OF ORIENTAL MEDICINE"

Introductioin. Polycomponent medicines are widely used in traditional medicine of many countries. Herb teas are a striking example of a traditional herbal preparation. The determination of their complete chemical composition will allow us to assume the direction of physiological activity. One of the main classes of biologically active substances of medicinal plants are essential oils with a variety of pharmacological effects, including antibacterial, sedative, anti-inflammatory, immunomodulatory, antispasmodic activity. In connection with the above, it is relevant to study essential oils both in the herb teas and in the final dosage form – infusion. The aim of the study is to determine the component composition of essential oils of herb teas, manufactured by the APHCI "RCHRT "Center of Ori-ental medicine", and identify the components that pass into the infusion – final dosage form. Material and methods. The object of the study was polycomponent herb teas according to the prescriptions of the traditional Tibetan medicine, manufactured by the APHCI “RCHRT “Center of Oriental medicine”, which including only pharmacopoeial species. Essential oils from the herb teas were isolated by hydrodistillation, and from infusions by hexane extraction. The qualitative composition and quantitative content of the essential oil compo-nents were determined by gas chromatography-mass spectrometry. Results. The essential oils of the polycomponent herb teas according to the prescriptions of the traditional Tibetan medicine, manufactured by the APHCI "RCHRT "Center of Oriental medicine" were studied. The chemical constituents is represented by mono- and sesquiterpene compounds, the qual-itative composition and relative contents of individual components vary depending on the herb teas composition. It is noted that less volatile compo-nents of essential oils are present in the obtained infusions. Conclusions. The obtained data indicate that the herb teas, depending on the plants used, contain essential oil, the components of which, passing in-to the infusion, along with other biologically active substances, can have a complex polytarget pharmacological effect
