Sulfoquinovosyldiacylglycerol (SQDG) contents in conifer leaves and their fatty acid (FA) compositions were determined. The SQDG content was 16-36 mg/100 g, and was high in Picea glehnii. Palmitic and alpha-linolenic acid were the usually predominant FAs. In Picea, the proportion of alpha-linolenic acid was low, and those of oleic and linoleic acid were high. The essential oil residues of Abies...

This work studied the antioxidant and anti-colorectal cancer properties of a potential strain thraustochytrids, Schizochytrium sp. (SMKK1), isolated from mangrove leaf litter. The biomass was extracted with methanol screened for activity using six different assays. extract exhibited highest total (87.37 ± 1.22%) lowest nitric oxide radical (75.12 2.22%), increased concentration extract. methano...

This study examined the effects of dietary alpha-linolenic acid deficiency followed or not by supplementation with phospholipids rich in n;-3 polyunsaturated fatty acid (PUFA) on the fatty acid composition of total phospholipids in 11 brain regions. Three weeks before mating, mice were fed a semisynthetic diet containing both linoleic and alpha-linolenic acid or deficient in alpha-linolenic aci...

Pure preparations of phosphatidylcholine were isolated from spinach leaf chloroplasts, spinach leaf microsomes, and cauliflower inflorescence. The isolated phosphatidylcholine was treated with snake venom phospholipase A, and the fatty acid distribution and composition of the fatty acid methyl esters prepared from the lysophosphatidylcholine and the freed fatty acid were determined by gas-liqui...

Diepoxides of linolenic acid were found to be chemoattractants. The concentration that produces 50% of maximal chemotaxis was 4.5 10(-7) mol/l for human neutrophils when investigated in a chemotaxis test based on the method of spectrophotometric determination of myeloperoxidase activity with buffers containing bovine serum albumin. Leukotriene B4 was used as positive control. The concentration ...

Vessel occlusion is the most frequent cause for impairment of local blood flow within the brain resulting in neuronal damage and is a leading cause of disability and death worldwide. Polyunsaturated fatty acids and especially alpha-linolenic acid improve brain resistance against cerebral ischemia. The purpose of the present study was to evaluate the effects of polyunsaturated fatty acids and pa...

High oleic soybean (HOSBO) and low linolenic acid soybean (LLSBO) oils were evaluated individually and in a 1:1 blend along with cottonseed oil (CSO) to determine frying oil stabilities and the flavor quality and stability of potato chips. Potato chips were fried in the oils for a total of 25 h. Potato chips and oils were sampled periodically for sensory data, gas chromatographic volatile compo...

Reactive oxygen species (ROS) are elevated by metabolic changes in diabetes, including autoxidation and increased advanced glycation. Endogenous protection by the glutathione redox cycle is also compromised by the competing NADPH requirement of elevated polyol pathway flux. Antioxidant treatment strategies prevent or reverse nerve conduction velocity (NCV) deficits in diabetic rats. These inclu...

Nanoemulsion is an alternative and promising approach to overcome insolubility and bioavailability problems of bioactive compounds. In this study, the sonication parameter for preparing nanoemulsions with high α- tocopherol and linolenic acid content were optimized by using response surface methodology and their stability were evaluated during 2 months’ storage. The response surface analysis re...
