ABSTRACT
Abstract@#Since ancient times, In traditional medicine has been widely used for Tan medicine, which make to natural raw material. Nowadays, this practice has been renewed, and researches are being conducted to determine their chemical component, mineral content and to explain their activating mechanism. Compounds with antioxidant activity contained in the pharmaceutical raw materials has very important benefits for metabolism, organ system function and to inhibit inflammation, oxidation reaction. In Mongolian traditional medical sources literature noted that bark (Larix sibirica Ldb) has activity such as anticoagulant, anti-cancer, anti-flu and to decrease arterial hypertension and also it was included to composition of "Tanchin-25" reception. Spectrometry and Rentgen fluorescence spectroscopy were used to identify chemical composition and content of mineral in the sample of Larix bark (Larix sibirica Ldb). According to the exploration, content of total flavonoid were determined 0.773%, and by mineral test, essential macro and micro elements that were obtained Ca (18.74%), Mg (8.31%), P (13.29%), K (2.49%), Na (0.675%), Cu-(375ppm), Zn(715ppm), Cr (68ppm) and V (17ppm), Co (5ppm).
