Abstract

In this study, the changes of anthocyanin content, total phenols, antioxidant capacity, microbiota composition before and after digestion and intestine fermentation in stomach and intestine were studied. The results indicated that after simulated gastrointestinal digestion, compared with the original sample, the total phenol content and anthocyanin content of intestinal digestion group for 2 h (ID 2 group) decreased by 53.64% and 70.45%, respectively, DPPH inhibition rate was 32.75% and T-AOC values of the extracts decreased to 62.89U/mg. The anthocyanins were identified to be composed of cyanidin-3-arabinoside, cyanidin-3-galactoside, cyanidin-3-xyloside, and cyanidin-3-glucoside. Black Chokeberry ( (Michx.) Elliot) anthocyanins significantly increased the relative richness of , promoted the growth of , , , and inhibited the growth of , , , etc. Anthocyanins have a positive regulatory effect on intestinal flora. These studies also provide essential information for the development of anthocyanin related health care products and drug products.

摘要

本研究对黑果腺肋花楸(Aronia melanocarpa (Michx.) Elliot)花青素含量、总酚、抗氧化能力、胃肠消化及肠道发酵前后的微生物群组成变化进行了研究。结果表明,模拟胃肠消化后,与原样相比,肠道消化2 h组(ID 2组)的总酚含量和花青素含量分别下降了53.64%和70.45%,提取物的DPPH抑制率为32.75%,T-AOC值降至62.89U/mg。花青素被鉴定为由矢车菊素-3-阿拉伯糖苷、矢车菊素-3-半乳糖苷、矢车菊素-3-木糖苷和矢车菊素-3-葡萄糖苷组成。黑果腺肋花楸花青素显著增加了双歧杆菌属(Bifidobacterium)的相对丰度,促进了双歧杆菌属(Bifidobacterium)、乳杆菌属(Lactobacillus)、阿克曼氏菌属(Akkermansia)、粪杆菌属(Faecalibacterium)的生长,并抑制了肠杆菌属(Enterobacter)、埃希氏菌属(Escherichia)、志贺氏菌属(Shigella)等的生长。花青素对肠道菌群具有正向调节作用。这些研究也为花青素相关保健品和药品的开发提供了重要信息。
