The objective of the study was to evaluate the effects of different vegetable oils [red palm olein (RPO), palm olein (PO), corn oil (CO) and coconut oil (COC)] on lipid profile in rat. Sixty six Sprague Dawley male rats were randomly divided into eleven groups of 6 rats per group and were treated with 15% concentrations of RPO, PO, CO and COC for 4 and 8(More)
A new computational approach for the determination of 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity (DPPH-RSA) in food is reported, based on the concept of machine learning. Trolox standard was mix with DPPH at different concentrations to produce different colors from purple to yellow. Artificial neural network (ANN) was trained on a(More)
Wild rice (Oryza rufipogon L) is known as an important germplasm that has specific desirable attributes and a high genetic diversity. The physicochemical and antioxidant properties of O. rufipogon Griff. (acc. IRGC105491), a wild rice collected from Malaysia that was used in a breeding program and a QTL mapping study, were assessed to determine the rice’s(More)
A stable chromogenic radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) is commonly used for the determination of antioxidant activity. In this paper, DPPH was dried into 96 well microplate to produce DPPH dry reagent array plate, based on which the highly sensitive and high throughput determination of antioxidant activities was achieved. The spectrophotometric(More)
The objective of the study was to evaluate the effect of four different vegetable oils [red palm olein (RPO), palm olein (PO), corn oil (CO), coconut oil (COC)] on antioxidant enzymes activity of rat liver. Sixty six Sprague Dawley male rats which were randomly divided into eleven groups of 6 rats per group and were treated with 15% of RPO, PO, CO and COC(More)
Four fruits namely Psidium guajava (seed guava), Mangifera indica var. Chakonan (Chakonan mango), Citrus sinensis var. Navel (Navel orange) and Malus sylvestris (Granny Smith apple) were analysed before the peels were studied for their total phenolic content (TPC), total flavonoid content (TFC), in-vitro antioxidant activities using four assays including(More)
Fruit peels are the major agro-industrial wastes in canned fruit manufacture and fruit juice processing which make it worth to investigate on their bioactive phenolic compounds. This study discussed on the total phenolic content (TPC), the quantification of eight individual bioactive phenolics using HPLC and evaluation of antioxidant activitu using DPPH(More)
BACKGROUND Coconut oil is commonly used as herbal medicine worldwide. There is limited information regarding its effects on the developing embryo and infant growth. METHODS We investigated the effect of virgin coconut oil post-natally and until 6 weeks old in mice (age of maturity). Females were fed with either standard, virgin olive oil or virgin coconut(More)
