In the present study, chemical characterisation, thermal analysis and antibacterial activity of honeys from spp. with occurrence in Caatinga biome of Brazil. The honeys presented pH from 4.07 to 4.14, density of 1.41 g/cm and °Brix value of 79.90. The thermogravimetry (TG) analysis presented six-seven events and differential thermal analysis (DTA) presented three-four endothermic peaks. HPLC fingerprint revealed a predominant presence of gallic acid and vanillin. Antioxidant activity evaluated using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) radical scavenging with IC values in the range of 14.5404 to 15.2454 mg/mL. The honeys also showed antimicrobial activities against and using a modified agar diffusion and microdilution method. The results of the present study demonstrate that the honey from stingless bees by Caatinga biome indicate polyphenol compounds, antioxidant activity and antimicrobial potential. The analytical methos permitted of fingerprint of samples.
在本研究中，对来自巴西卡廷加生物群落中 属蜜蜂所产蜂蜜进行了化学表征、热分析和抗菌活性研究。这些蜂蜜的pH值在4.07至4.14之间，密度为1.41 g/cm，波美度值为79.90。热重分析（TG）显示有六到七个事件，差示热分析（DTA）显示有三到四个吸热峰。高效液相色谱指纹图谱显示没食子酸和香草醛占主导地位。使用2,2-二苯基-1-苦基肼自由基（DPPH）清除法评估抗氧化活性，IC值在14.5404至15.2454 mg/mL范围内。这些蜂蜜还采用改良的琼脂扩散法和微量稀释法对 和 显示出抗菌活性。本研究结果表明，来自卡廷加生物群落的无刺蜂蜂蜜具有多酚化合物、抗氧化活性和抗菌潜力。分析方法允许对样品进行指纹图谱分析。
