Stability assessment of anthocyanins from black soybean, grape, and purple sweet potato under in vitro gastrointestinal digestion.

ABSTRACT: Anthocyanins are glycosylated derivatives of anthocyanidins, whose hydroxyl groups are occasionally acylated with organic acids. The effect of anthocyanin composition on their stability under in vitro gastrointestinal digestion was investigated. Black soybean had all glycosylated anthocyanins with monosaccharide, grape contained glycosylated anthocyanins with disaccharide (23%) and acylated anthocyanins bound with two sugars (77%), and purple sweet potato had all acylated anthocyanins bound with three sugars. The order of total anthocyanins content was purple sweet potato, grape, and black soybean. Gastric digestion did not significantly decrease anthocyanins content in three samples, while intestinal digestion resulted in the significant decrease of total anthocyanins content in black soybean (40%), grape (45%), and purple sweet potato (25%). This indicates that the degree of glycosylation and acylation of anthocyanins affects their stability under the gastrointestinal conditions. Phenolic acids derived from anthocyanin degradation increased total phenolic content as well as ABTS radical scavenging activity.

Project description:This study was conducted to investigate the beneficial effect of purple sweet potato anthocyanins (PSPA) on growth performance, oxidative status, immune response, intestinal morphology, and intestinal flora homeostasis in heat-stressed Wenchang chickens. A total of 100 Wenchang chickens (50-day-old) were randomly assigned to 5 groups, including the thermoneutral environment (TN) group (26°C); high-temperature stressed (HS) group (33°C ± 1°C); low-dose PSPA treatment (L_HS) group (8 mg/kg body weight, 33°C ± 1°C); medium-dose PSPA treatment (M_HS) group and high-dose PSPA treatment (H_HS) group (16 mg/kg and 32 mg/kg body weight, respectively, 33°C ± 1°C). The results showed that PSPA reversed the adverse effects of heat stress on growth performance, meat quality, and carcass characteristics. And the effect was associated with the concentration of PSPA partially. Heat stress increased the serum lipids of Wenchang chickens. LDL-C, TG, TC, and FFA in the serum were significantly decreased, and HDL-C and LPS in the serum were increased by PSPA treatment. The digestive enzymes in duodenal chyme were significantly (P < 0.05) increased by PSPA treatment. And PSPA treatment significantly (P < 0.05) enhanced the redox status by improving antioxidant parameters (GSH-Px and SOD) and decreasing the MDA level in the serum and liver. Moreover, the level of inflammatory cytokines was significantly (P < 0.05) regulated by PSPA treatment compared to the HS group. The villus length and goblet cell numbers after PSPA treatment were significantly higher than HS group. Furthermore, PSPA also played protection on the intestine structure by decreasing the level of D-LA and DAO. 16S rRNA sequencing revealed the microbial composition was altered by PSPA, and Acetanaerobacterium and Oscillibacter were dominant in the H_HS group. Microbial functional prediction indicated that function pathways based on KEGG and metacyc database were regulated by PSPA, and intestinal flora correlated with metabolic function significantly. The spearman correlation analysis showed that Saccharibacteria and Clostridium_IV correlated with the serum lipids, antioxidant, and inflammatory cytokines. Collectively, these findings suggest that PSPA has a positive effect against heat stress in poultry.
