Agro-industry yields ample quantity of several byproducts with considerable importance. These byproducts are mostly under-utilized, often used as animal feed or rejected as waste; hence their true potential is not harnessed. The use of such superfluous resources is of not only economic significance but also a form of commercial recycling. Rice bran is an important byproduct of rice milling industry with a global potential of 29.3 million tons annually. It is gaining great attention of the researchers due to its nutrient-rich composition, easy availability, low cost, high antioxidant potential, and promising effects against several metabolic ailments. Bioactive components of rice bran, mainly γ-oryzanol, have been reported to possess antioxidant, anti-inflammatory, hypocholesterolemic, anti-diabetic, and anti-cancer activities. Rice bran oil contains appreciable quantities of bioactive components and has attained the status of "Heart oil" due to its cardiac-friendly chemical profile. Nutraceutics have successfully been extracted from rice bran using several extraction techniques such as solvent extraction, supercritical fluid extraction, microwave-, and ultrasonic-assisted extraction. Current paper is an attempt to highlight bioactive moieties of rice bran along with their extraction technologies and health benefits.
农业产业产生了大量具有相当重要性的副产品。这些副产品大多未得到充分利用，通常用作动物饲料或作为废物丢弃；因此，它们的真正潜力尚未得到开发。利用这些多余的资源不仅具有经济意义，而且是一种商业回收形式。米糠是稻米加工业的重要副产品，全球每年的潜在产量为 2930 万吨。由于其营养丰富的成分、易于获取、成本低、高抗氧化潜力以及对多种代谢疾病的有希望的影响，它引起了研究人员的极大关注。米糠中的生物活性成分主要是γ-谷维素，据报道具有抗氧化、抗炎、降胆固醇、抗糖尿病和抗癌作用。米糠油含有相当数量的生物活性成分，并因其对心脏友好的化学特性而获得了“心脏油”的地位。营养保健品已成功地从米糠中提取出来，使用了几种提取技术，如溶剂提取、超临界流体提取、微波和超声辅助提取。本文旨在强调米糠的生物活性成分及其提取技术和健康益处。
