1 Results, processing: The coefficient of dryness (Ksuh.) Is the ratio of the mass of dry material to the mass of material before drying. Forthyme: А = 11,88 г В = 13,98 г С = 13,81 г Tocollect: А = 12,11 г В = 14,11 г С = 13,93 г X (thyme)= 8,1% К dry = 0,92 X (collection)= 9,0 % К dry = 0,91 The moisture content of the feed was determined by drying in an oven. Weighed sample was dried at 105 degrees to constant weight. The moisture content and the coefficient of dryness were determined by the formulas presented on the slide. The moisture content in the thyme herb was 8.1%, and in the collection - 9%. 2 Results, processing: First parallel: Va ( Thyme) = 11,4 sm 3 Va (Collection) = 5,8 sm 3 Second parallel : Va ( Thyme) = 11,6 sm 3 Va ( Collection) = 5,6 sm 3 АОА( Thyme) = 920 mgО 2 / dm 3 АОА( Collection) = 456 mg О 2 / dm 3 Permanganate AA was determined by the Leventhal method. The method is based on the ability of aqueous extracts of plant materials to be rapidly oxidized by potassium permanganate. The oxidizability of the aqueous extract was determined. T.O. The AOA of the thyme extract was 920 mg O2 / dm3, and the AOA of the harvest extract was 456 O2 / dm3 3 Results, processing: Table 1.Determination of antioxidant activityin thyme and BAS V NaOH , sm 3 BAS Thyme 1 3,20 2,40 2 3,20 2,35 Table 2.Determination of antioxidant activity in thyme and BAS Sample К, degrees DS 11,30 Thyme 8,30 The acidity of plant materials was determined. Water was added to the weighed portions of the raw material, triturated, and the mixture was filtered. The filter was titrated with alkali with 12 phenolphthalein indicator until a red color appeared. The slide shows the filtrate before (left) and after (right) titration. The acidity of raw materials was determined by the formula; it amounted to 11.3 degrees for dietary supplements and 8.3 degrees for thyme. 4 Results, processing: X= ) 100 ( 100 100 100 0 0 W m D m D x x ,D x - the optical density of the test solution;D 0 -optical density of the RSO routine; (obtained from the teacher); m x - mass of raw materials (g);m 0 - mass of rutin in PCO (0.035 g);W - moisture content in plant raw materials (%) Based on the results obtained, a table is drawn up and the optimal time for the extraction of flavonoids is determined. Table 3.determination of flavonoidsdetermination of flavonoids in thyme and BAS Sample Х, % DS 30 min 0,39 DS 45 min 0,40 Thyme 30 min 0,75 Thyme 45 min 0,88 Figure 1.Absorption Spectra of Serpylliherba Plant Extracts and Sedative Collection The amount of flavonoids was determined. To do this, the plant material was extracted with alcohol, the first part of the extracts was kept for 30 minutes, the second - 45 minutes. The absorption spectra were filtered and recorded on a Specord 50 instrument. The wavelength corresponding to the absorption maximum of flavonoids was selected. The amount of flavonoids calculated in terms of rutin was calculated. The results show that the optimal extraction time is 45 minutes. Moreover, the content of flavonoids in the thyme is greater than in dietary supplements. In Russia, the content of flavonoids in plants of the genus Thymus (including T. serpyllum and T. vulgaris widely used in official medicine) has been little studied. The sum of flavanoids according to volume 3 of the 2013 Pharmacopoeia is considered in terms of luteolin-7-O-glucoside. In the article validation of methods of quantitative determination of the amount of flavonoids in the trees of the thyme scientific reports belsu series medicine.pharmacy. 2012. no. 22 (141).issue 20/1 there is data on the content of the total flavanoid in terms of luteolin 1.34% and cinaroside 0.3 mg. 13 the total content of quercetin is 3.54% in the article features of accumulation of pharmacologically significant compounds in representatives of the genus thymyan (thymus l.) жүктеу/скачать 12,12 Mb.
