0000023498 00000 n The less polar fraction II was analyzed by a capillary GC-MS after methaneboronation. The physicochemical characteristics of flaxseed hull oil at maturity were as followsI: iodine number ~170, saponification value ~178 and peroxide value ~1.80 (Herchi et al., 2014). The total content of chlorophylls remained the same or increased during ripening of the galbuli from location 1 and 3, but slightly decreased in the ripe ones from location 2. At first it is used in the industry among all of the vegetable fiber. Among the 7 sugars, the hexose levels were the highest (73.85%). Fatty acids with carbon chain varying from 10 to 22 and unsaturation varying from 0-6 double bonds are of common occurrence. 0000022828 00000 n All of the Hepatoprotective properties from the seaweed Bryothamnion triquetrum (S.G.Gmelin) M.A.Howe against C...

The bioactive fractions with 0.65-0.75 of elution volume/total volume were combined, dissolved in small volume of methanol, and subjected to a reversed phase HPLC (8 × 100 mm, 4mm, Novapak C18 column) at a flow rate of 1 mL min −1 with 45% acetonitrile. 0000007829 00000 n In recent years flaxseed has become known as a functional food due to its nutritional composition, which has positive effects on disease prevention providing health-beneficial components such as alpha-linolenic acid (Bozan and Temelli, 2008), lignans and 0000014469 00000 n An analysis of brown Canadian flax averaged 41% fat, 20% protein, 28% total dietary fibre, 7.7% moisture and 3.4% ash, which is the mineral-rich residue left after samples are burned (11). This study is aimed to check the mineral and chemical composition of defatted flaxseed as, it's getting fame by nutritionist, pharmaceutical and food industry. 2017;Khan et al. Extracts equivalent to 300 g fresh weight tissue were bioassayed by the rice lamina inclination test. we can conclude from here that the way atoms are put together, the density, colour, strength and other ~ %%EOF is an evergreen tree and a rare plant found in very few locations in southern Bulgaria. Results showed that these seeds contained 4.93, 22.28, 36.03, 31.03, 18.03, 3.63and 1.08% (ww) of moisture, protein, fat, total carbohydrates, crude fiber, ash and reducing sugars respectively with 1.83mg 100 gm sample of Vitamin C. Results of amino acids analysis indicated aspartic acid, glutamic acid , arginine as non –essential and tryptophan and phenylalanine as essential amino acids to be the main components of seeds protein , they represent 4.522, 3.486, 1.88 and 2.414, 0.695 gm /100gm sample respectively. The flaxseed composition is given in Table 1. The maximum level of total phenolic acid content (128.3 mg/100 g oil) was reached at 7 DAF. A significant increase in the carbohydrates content of the hull was observed during development. Antioxidant capacity, nutritional and functional quality of wheat bread supplemented with 1–5% flaxseed hull (FH) were studied. Also, it was evaluated the expression of antioxidant enzymes by RT-PCR. 0000037232 00000 n 0000022387 00000 n 2008;Scott et al.
