Based on ancestral knowledge towards health beneficial effect, the current study led to investigate the content of bioactive phytochemical(s) in the scented rice (variety “joha”) grain indigenous to the NER-India and their effects on the enzyme involved in metabolic disorders and cellular glucose uptake efficacy. Results of both α-glucosidase inhibitory activity and the glucose uptake assay-guided fractionation based on column purification followed by spectral data analysis confirmed the presence of two major bioactive compounds as linoleic (ω-6-fatty-acid) and linolenic (ω-3-fatty-acid) acid. Quantitative analysis showed that linolenic acid content in scented rice verities was 2.1±0.3 mg/g, which is ~1.6 fold higher than its content in non-scented rice variety from the same region. The relative ratio (ω-6/ω-3) of these two essential unsaturated fatty acids content in the scented rice variety seeds was calculated as 23.5±0.6 while, in non-scented rice variety seeds, it was 31.6. Chemical fingerprinting by GCMS and HPLC of methanolic extract of selected rice samples revealed the presence of various fatty-acid along with other volatile and polar compounds. In conclusion, the scented rice seeds contain a better ratio of two essential unsaturated fatty acid compare to non-scented rice seed, which may be an effective choice as diet towards controlling metabolic disorder.

对选定香米品种（Oryza sativa）中生物活性植物化学物质的定量分析表明，其摄入具有对抗代谢紊乱的优势

基于对健康有益作用的祖先知识，当前的研究导致调查了印度东北印度产的香米（品种“ joha”）籽粒中生物活性植物化学成分的含量及其对代谢紊乱中涉及的酶的影响和细胞摄取葡萄糖的功效。基于柱纯化的α-葡萄糖苷酶抑制活性和葡萄糖摄取测定指导的分馏结果，然后进行光谱数据分析，结果证实存在两种主要的生物活性化合物，如亚油酸（ω-6-脂肪酸）和亚麻酸（ω-3） -脂肪酸）酸。定量分析表明，香米中的亚麻酸含量为2.1±0.3 mg / g，比同一地区非香米中的亚麻酸含量高约1.6倍。计算出香米品种种子中这两种必需不饱和脂肪酸含量的相对比（ω-6/ω-3）为23.5±0.6，而无香米种子中的相对比例为31.6。通过GCMS和HPLC对选定大米样品的甲醇提取物进行的化学指纹分析显示，存在各种脂肪酸以及其他挥发性和极性化合物。总之，与非香米种子相比，香米种子包含两种必需的不饱和脂肪酸的比例更高，这可能是控制代谢紊乱的有效选择。通过GCMS和HPLC对选定大米样品的甲醇提取物进行的化学指纹分析显示，存在各种脂肪酸以及其他挥发性和极性化合物。总之，与非香米种子相比，香米种子包含两种必需的不饱和脂肪酸的比例更高，这可能是控制代谢紊乱的有效选择。通过GCMS和HPLC对选定大米样品的甲醇提取物进行的化学指纹分析显示，存在各种脂肪酸以及其他挥发性和极性化合物。总之，与非香米种子相比，香米种子包含两种必需的不饱和脂肪酸的比例更高，这可能是控制代谢紊乱的有效选择。
