This study evaluated the physicochemical, nutritional, antioxidant, and phenolic properties of ten honey samples from the Sundarbans mangrove forest, Bangladesh. The average pH, electrical conductivity, total dissolved solid, ash, moisture, hydroxymethyl furfural, titrable acidity, and absorbance were 4.3, 0.38 mS/cm, 187.5 ppm, 0.14%, 17.88%, 4.4 mg/kg, 37.7 meq/kg, and 483 mAU, respectively. In the honeys, the average contents of Ca, Cu, Fe, K, Mg, Mn, and Na were 95.5, 0.19, 6.4, 302, 39.9, 3.4, and 597 ppm, respectively, whereas Cd, Cr, Pb, and Ni were not found. The average contents of total sugar, protein, lipid, vitamin C, polyphenols, flavonoids, and anthocyanins in the honeys were 69.3%, 0.8%, 0.29%, 107.3 mg/kg, 757.2 mg gallic acid equivalent/kg, 43.1 mg chatechin equivalent/kg, and 5.4 mg/kg, respectively. The honeys had strong 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity, reducing power and total antioxidant capacity. High-performance liquid chromatography analysis of the honey fractions revealed the quantification of six polyphenols namely, (+)-catechin, (-)-epicatechin, -caumeric acid, syringic acid, -cinnamic acid, and vanillic acid at 194.98, 330.34, 74.64, 218.97, 49.55, and 118.84 mg/kg, respectively. Therefore, the honeys in the Sundarbans are of excellent quality and a prospective source of polyphenols, and antioxidants.
本研究评估了来自孟加拉国孙德尔本斯红树林的10个蜂蜜样本的物理化学、营养、抗氧化和酚类特性。平均pH值、电导率、总溶解固体、灰分、水分、羟甲基糠醛、可滴定酸度和吸光度分别为4.3、0.38 mS/cm、187.5 ppm、0.14%、17.88%、4.4 mg/kg、37.7 meq/kg和483 mAU。在这些蜂蜜中，钙、铜、铁、钾、镁、锰和钠的平均含量分别为95.5、0.19、6.4、302、39.9、3.4和597 ppm，而未检测到镉、铬、铅和镍。蜂蜜中总糖、蛋白质、脂质、维生素C、多酚、黄酮类化合物和花青素的平均含量分别为69.3%、0.8%、0.29%、107.3 mg/kg、757.2 mg没食子酸当量/kg、43.1 mg儿茶素当量/kg和5.4 mg/kg。这些蜂蜜具有较强的1,1-二苯基-2-苦基肼自由基清除活性、还原能力和总抗氧化能力。对蜂蜜组分的高效液相色谱分析显示，定量测定了六种多酚，即(+)-儿茶素、(-)-表儿茶素、阿魏酸、丁香酸、肉桂酸和香草酸，含量分别为194.98、330.34、74.64、218.97、49.55和118.84 mg/kg。因此，孙德尔本斯的蜂蜜质量上乘，是多酚和抗氧化剂的潜在来源。
