Innovation: The team of Professor Li Juxiu of Xinong and the team of researcher An Wei of Ningxia Academy of Agriculture and Forestry found that Lycium ruthenicum anthocyanins can enrich intestinal short-chain fatty acid producing bacteria (Rumenococcus, Bacteroides, etc.
), increase the content of SCHAs, and reduce production.
Endotoxin bacteria (such as Helicobacter and Desulfovibrioceae) and reduce the level of endotoxin (such as LPS); it can activate GPRs, inhibit HADC activity, reduce intestinal permeability, protect the integrity of intestinal barrier, and improve intestinal inflammation reaction.
Keywords: Lycium ruthenicum anthocyanins, high-fat diet, intestinal flora, colonic barrier dysfunction, inflammation of the colon, Lycium ruthenicum Murr.
(Lycium ruthenicum Murr.
), as a unique medicinal and edible plant resource in Northwest China, its fruit It has a variety of physiological functions such as lowering lipid, lowering blood sugar, anti-oxidation and anti-obesity, and is safe and non-toxic.
It is an ideal edible product.
Known as the "king of anthocyanins", Lycium ruthenicum anthocyanins (AC) are rich in fruit, among which petunia anthocyanins are as high as 97% and aromatic acids are acylated.
In 2018, Professor Li Juxiu's team and An Wei researcher team (Baoming Tian; Jianhua Zhao; Wei An; Jiawei Zhang; Xin Cao; Jiale Mi; Jinsong Zhao; Yingxiao Zhang; Juxiu Li(*), Lycium ruthenicum diet alters the gut microbiota and partially enhances gut barrier function in male C57BL/6 mice, Journal of Functional Foods, 2019, 52: 516-528) reported that Lycium ruthenicum can change the intestinal flora of normal mice, promote the production of intestinal SCFAs, and reduce LPS content , Enhance the intestinal barrier function.
Elimination of intestinal flora with antibiotics confirms that the effect of dietary supplementation of Lycium ruthenicum on intestinal health is related to the improvement of intestinal flora and intestinal mucosal barrier function.
It is necessary to explore the material basis and mechanism of the effects of Lycium ruthenicum.
The research team used Lycium ruthenicum as the raw material to extract and purify Lycium ruthenicum anthocyanins (AC).
Using mice induced by a high-fat diet as an animal model, the research team studied the effects of Lycium ruthenicum anthocyanins on the body weight and intestinal flora of mice.
Intervention effects of intestinal metabolites, intestinal barrier, and intestinal inflammation: Studies have found that AC can regulate the imbalance of intestinal flora and reduce the colon barrier damage and intestinal inflammation in mice induced by high fat.
The relevant results were published in Molecular Nutrition & Food Research.
AC can reduce the weight gain of mice induced by HFD, and increase the OTU and α diversity of the mouse flora induced by HFD, change the β diversity of the flora closer to the control mice, and reduce Firmicutes and Bacteroides At the same time, AC increased the relative abundance of SCFAs-producing bacteria such as Rumen Bacteria, Muribaculaceae, Akkermansia, Ruminococcaceae_UCG-014 and Bacteroides, and decreased the abundance of LPS-producing bacteria such as Desulfovibrioceae and Helicobacter.
AC can increase the content of SCFAs in the colon contents and stool samples of mice induced by HFD, and reduce the pH, free ammonia and LPS content of the intestine and stool.
AC ameliorated pathological damages such as inflammatory cell infiltration and edema in intestinal tissue caused by HFD, increased the length of HFD-induced mouse colon microvilli, by activating G GPRs and inhibiting HDACs activity, increasing tight junction mRNA and protein expression levels, and improving The tight junction structure of the colon reduces the permeability of the intestine and enhances the barrier function of the intestine; AC reduces the intestinal inflammation in mice caused by HFD by inhibiting the LPS/TLR4/NF-κB signaling pathway.
