“…According to global rice production, paddy rice become created around 678 million metric loads in 2014. [1] Broadly speaking, the composition of the whole rice grain is comprised (63.6-73.2%) carbohydrate, (1.5-2.3%) fat, (5.8-7.7%) protein, (7.2-10.4%) fiber, and (2.9-5.2%) ash content. [2] Rice grain contains three parts which include major portion, i.e., endosperm or white rice (~70%), hull/husk (~20%), and bran (~10%).…”

Rice bran is fabricated from the rice milling enterprise and contains about 10% of the entire weight of rough rice. It is especially composed of aleurone, pericarp, subaleurone layer, and germ. Rice bran is a fertile supply of nutrients, minerals, vital fatty acids, dietary fiber, and different sterols. The quantification of γ-oryzanol in rice bran can be conducted by many methods that require drawing out of rice bran oil (RBO) from the bran, accompanied by way of evaluation of the quantity of γ-oryzanol in the RBO with the aid of high-performance liquid chromatography. RBO is the oil drain out of the outer rigid surface of rice called chaff (rice husk). It is identified for its excessive smoke factor of 232°C (450°F) and soft taste, making it pleasant for excessive-temperature cooking strategies such as blend and deep frying. It is healthy for human expenditure, which is employed in the system of vegetable ghee. Wax was drawn out of RBO and palpanese extract, which is employed for carnauba wax in makeup, confectionery, shoe lotions, and sharpening compounds. It is accepted as a food preparation oil in numerous Asian countries, along with Bangladesh, Japan, India, and China. Regarding the importance of RBO, this overview intends to pay attention at the phytochemistry and therapeutic functions of RBO.

“…It's ideal fatty acid constituents and presence of naturally producing biologically active and antioxidant compounds makes it nutritious oil. In addition, accumulating evidence suggests that RBO can lower blood cholesterol, boost immune response and may help prevent cancer [5][6][7][8][9][10][11][12].…”

Objective: To study the pre and post synaptic 5-HT1A receptor dependent responses in rats following Rice bran oil (RBO) treatment. Methods:Male albino Wistar rats were first categorized into two groups. Standard rodent food was given to all groups. RBO-treated rats were given RBO (0.2 ml/day) daily for six weeks. After six weeks, the rats were subdivided into further two groups. Rats of first subgroup were injected with saline and second group with 8-hydroxy-2-(di-npropylamino) tetralin (8-OH-DPAT) at a dose of 0.25 mg/kg. 8-OH-DPAT-induced behavioral activity was monitored just after 5 minutes of injections till 25 minutes. One hour after saline or drug injections, animals were sacrificed. Plasma and brain samples were then stored for the estimation of cholesterol, glucose and corticosterone in plasma and concentrations of serotonin in brain.Results: Intensity of serotonin syndrome produced by 8-OH-DPAT and the effects of the drug on plasma glucose and corticosterone were greater in RBO treated than control rats suggesting that the treatment decreases postsynaptic 5-HT1A receptor dependent responses. Drug-induced decreases of brain 5-HT metabolism, a measure of presynaptic 5-HT1A receptor dependent response were also attenuated in RBO treated rats.Conclusion: Down regulation of 5-HT1A autoreceptor receptor mediated feedback control over 5-HT synthesis and release is possibly played a role to have opposed the depression like effects by RBO.

Preliminary evidence, including small double-blind, placebo-controlled trials, suggests that the gamma oryzanol portion of rice bran oil may contribute an additional cholesterol-lowering benefit beyond the effects of the fatty acids 9,10,11,12 .…”

Rice bran is the cuticle existing between the rice and husk of the paddy and consists of embryo and endosperm of the seeds of Oryza sativa, family Gramineae. It is obtained as a by product in rice mill during polishing of rice obtained after dehusking of paddy. Rice bran contains about 15% of fixed oil and is obtained by the solvent extraction method. It contains oleic acid, linolenic acid as unsaturated fatty acid and palmitic acid, stearic acid as a saturated fatty acid. The minor components of the rice bran, i.e. gamma oryzanol, phytosterols, and other phytosterol conjugates are examined to have antioxidant property against the free radicals. It is believed that rice bran serves as an important functional food that has cholesterollowering properties, cardiovascular health benefits, and anti-tumor activity. The oryzanol component acts as a protective agent against UV light-induced lipid peroxidation and hence can be used as a potent sunscreen agent. The ferulic acid and its esters present in gamma oryzanol stimulate hair growth and prevent skin aging.
