Biological Activity Evaluation of Specialty Honeys from Different Plant Sources
-
摘要:
目的 蜂蜜具有甘甜的滋味与良好的营养价值,近年来受到了食品、医药界的广泛关注。特种蜂蜜不仅拥有来自于植物的药用特性,也展现出了较强的抗氧化能力和抗菌活性。目前,对于中国特种蜂蜜的比对研究还相对较少,其开发利用仍有巨大的潜力与空间。 方法 检测分析33种不同植物来源的特种蜂蜜的理化指标和生物活性,通过DPPH自由基清除法和 FRAP 总抗氧化能力检测法对蜂蜜抗氧化活性进行评价,并使用琼脂扩散法和微量肉汤稀释法检测样品的抗菌活性。 结果 所有蜂蜜样品的理化指标均符合国家标准规定;在33种蜂蜜中,米团蜜具有最强的抗氧化活性,板栗蜜、藿香蜜也表现良好。对金黄色葡萄球菌和大肠杆菌抗菌能力最强的分别为茴香蜜和枸杞蜜。此外,蜂蜜的抗氧化能力与总酚含量呈显著正相关,与抗菌能力的相关性不显著。 结论 米团、茴香、藿香蜂蜜等是具有优良生物活性的特种蜂蜜,它们具有进一步开发利用的潜力和价值;本研究结果也可为当前蜂蜜消费市场等级评定提供依据。 Abstract:Objective Honey, with its sweet taste and exceptional nutritional value, has garnered extensive attention in the food and medical industries in recent years. Specialty honeys not only possess medicinal properties derived from plants but also exhibit robust antioxidant capabilities and antibacterial activity. Currently, there is relatively little comparative research on specialty honeys in China, indicating significant potential and opportunities for the development and utilization of specialty honey. Method This study investigated 33 varieties of special honey from different regions in China, conducting tests and analyses on their physicochemical properties and biological activities. The antioxidant activity of honey was evaluated through DPPH free radical scavenging experiments and FRAP total antioxidant capacity tests, while antibacterial activity was assessed using the agar diffusion method and microdilution method in broth. Result All honey samples met the national standard requirements for physicochemical properties. Among the 33 types of honey, Leucosceptrum honey exhibited the strongest antioxidant activity, while Chestnut honey and Agastache honey also performed well. Fennel honey and Goji honey showed the strongest antibacterial abilities against Staphylococcus aureus and Escherichia coli, respectively. Furthermore, the antioxidant capacity of honey showed a significant positive correlation with the total phenolic content, while its correlation with antibacterial capacity was not significant. Conclusion Some specialty honeys have exhibit excellent biological activities, indicating their potential value for further development and utilization. The results of this study can also provide a basis for the grading and evaluation of honey in the current consumer market. -
