    摘要:

    以中国常见的意蜂蜜(洋槐蜜、枣花蜜、荆条蜜、荔枝蜜)以及特色中蜂蜜(枇杷蜜、柃木蜜、苦丁茶蜜)为原料,探讨其模拟胃肠道消化与结肠发酵对肠道微生物的影响。结果表明,7种蜂蜜经体外模拟消化发酵后对肠道菌群有调节作用,均增加了放线菌门丰度,降低了厚壁菌门丰度,荔枝蜜、洋槐蜜、荆条蜜、苦丁茶蜜、枇杷蜜、柃木蜜和枣花蜜分别降低了30.08%,21.2%,34.83%,35.5%,32.73%,35.7%和30.41%。且不同蜂蜜对肠道菌群作用有显著差异,荔枝蜜、洋槐蜜、荆条蜜、苦丁茶蜜、枇杷蜜和柃木蜜增加了拟杆菌门丰度,荔枝蜜和洋槐蜜降低了变形菌门丰度。除枣花蜜外,其它6种蜂蜜均可降低厚壁菌门/拟杆菌门(Firmicutes/Bacteroidetes,F/B)值,荔枝蜜、洋槐蜜、荆条蜜、苦丁茶蜜、枇杷蜜和柃木蜜分别降低了341.99%,337.37%,106.36%,128.14%,141.59%和93.52%,其中荔枝蜜降低效果最好。蜂蜜对肠道菌群的作用效果与蜂蜜的植物源有直接的相关性,与蜜蜂的种类没有直接的相关性,厚壁菌门丰度与多酚总量呈负相关。

    Abstract:

    The effects of commonly found Chinese honey (acacia honey, jujube honey, vitex honey, and lychee honey) and specialty honey (loquat honey, cinnacle honey, and kuding tea honey) on gut microbiota after in vitro simulated gastrointestinal digestion and colonic fermentation were investigated. The results showed that all seven types of honey had a regulatory effect on gut microbiota, increased the abundance of Actinobacteria and decreased the abundance of Firmicutes, lychee honey, acacia honey, vitex honey, kuding tea honey, loquat honey, cinnacle honey, and jujube honey reduced Firmicutes abundance by 30.08%, 21.2%, 34.83%, 35.5%, 32.73%, 35.7%, and 30.41%, respectively. Different types of honey had significantly different effects on gut microbiota. Lychee honey, locust honey, vitex honey, bitter tea honey, loquat honey, and Chinese sumac honey increased the abundance of Bacteroidetes, while lychee honey and locust honey decreased the abundance of Proteobacteria. Except for jujube flower honey, all other six types of honey reduced the Firmicutes/Bacteroidetes(F/B) ratio, with reductions of 341.99%, 337.37%, 106.36%, 128.14%, 141.59%, and 93.52% for lychee honey, acacia honey, vitex honey, kuding tea honey, loquat honey, and cinnacle honey, respectively, with lychee honey having the best effect. The effects of honey on gut microbiota were directly related to the plant source of honey, rather than the type of honeybee. The abundance of Firmicutes was negatively correlated with the total polyphenol content.
