The North-Eastern region of India is known for its rich flora and has great potential for honey production. Honey samples collected from local markets of different regions of North-East India viz. Shillong, Sohra, Mawsynram, Jorhat and Tezpur were analyzed for physicochemical properties, bioactivity and mineral content. Effect of sonication time on the bioactive properties of honey was determined. All the honey samples had good bioactive properties and high content of potassium, sodium, calcium and iron. The Jorhat sample had the highest phenolic content (296.68 ± 2.16 mg GAE/100 g) and flavonoid content (155.26 ± 2.90 μg quercetin/100 g) whereas highest DPPH radical scavenging activity with an IC value of 29.8 ± 0.20 g and a FRAP value of 7291.60 ± 584.6 μM Fe(II)/100 g were noted in Shillong sample. Sonication exhibited various effects on the bioactive properties of the selected honey samples based on their source and treatment time. Honey from Jorhat and Sohra exhibited good quality standards with HMF content less than 80 mg/kg.
印度东北地区以其丰富的植物群而闻名，蜂蜜生产潜力巨大。对从印度东北部不同地区（即西隆、索拉、毛辛拉姆、乔哈特和提斯浦尔）当地市场采集的蜂蜜样本进行了物理化学性质、生物活性和矿物质含量分析。测定了超声处理时间对蜂蜜生物活性的影响。所有蜂蜜样本均具有良好的生物活性，钾、钠、钙和铁含量较高。乔哈特样本的酚类含量最高（296.68 ± 2.16毫克没食子酸当量/100克），黄酮类含量最高（155.26 ± 2.90微克槲皮素/100克），而西隆样本的DPPH自由基清除活性最高，IC值为29.8 ± 0.20克，铁还原抗氧化能力（FRAP）值为7291.60 ± 584.6微摩尔Fe(II)/100克。根据蜂蜜的来源和处理时间，超声处理对所选蜂蜜样本的生物活性表现出不同影响。乔哈特和索拉的蜂蜜质量标准良好，羟甲基糠醛（HMF）含量低于80毫克/千克。
