“…The result is similar withSharmila et al (2019) that reported the organic solvent combined with water may facilitate better extraction solvents of pigments that are soluble in water and organic solvent. So, ethanol-water solution was selected as the ideal extraction solvent for further study.3.2 | Single-factor experiment of GYP extractionSingle-factor experiments of GYP extraction were carried out with four selected parameters including ethanol concentration, liquid/ solid ratio, extraction time, extraction temperature, which provided a suitable range for the BBD(Gao et al, 2017).From Figure1a, the absorbance of GYP first increased with the ethanol concentration from 50% to 60%, then fell when the ethanol concentration was in the range of 60%-90%. The highest absorbance of GYP was 0.672 with the ethanol concentration of 60%.…”

Gardenia jasminoides var. radicans Makikno contains rich gardenia yellow pigment (GYP). In this study, the process of pigment extraction was optimized based on a Box–Behnken design (BBD) and response surface methodology (RSM). The absorbance and antioxidant activity (AA) were considered as responses. The result showed that the optimal extraction conditions were ethanol concentration 65.10%, liquid/solid ratio 10:1 ml/g, extraction time 59.85 min, and extraction temperature 60.04℃ for the maximal response values of absorbance (0.79) and AA (91.30%), respectively. Crude GYP was purified by the 13 different resins. The result showed that BJ‐7514 was suitable for purifying GYP with the absorption ratio of 95.4%. Moreover, the 80% of ethanol eluent is applicable on the BJ‐7514 with the desorption ratio of 91.93%. The major component of GYP (Crocin‐3) was isolated and identified from the purified GYP.

Ulcerative colitis (UC) is a chronic and nonspecific inflammatory disease of the colon and rectum, and its etiology remains obscure. Cherry polyphenols showed potential health-promoting effects. However, both the protective effect and mechanism of cherry polyphenols on UC are still unclear. This study aimed to investigate the potential role of the free polyphenol extract of cherry in alleviating UC and its possible mechanism of action. Our study revealed that the free polyphenol extract of cherry management significantly alleviated UC symptoms, such as weight loss, colon shortening, the thickening of colonic mucous layer, etc. The free polyphenol extract of cherry treatment also introduced a significant reduction in levels of malondialdehyde (MDA), myeloperoxidase (MPO) and nitric oxide (NO), while causing a significant elevation in levels of catalase (CAT), glutathione (GSH-Px), superoxide dismutase (SOD), as well as the downregulation of pro-inflammatory cytokines. This indicated that such positive effects were performed through reducing oxidative damage or in a cytokine-specific manner. The immunofluorescence analysis of ZO-1 and occludin proteins declared that the free polyphenol extract of cherry had the potential to prompt intestinal barrier function. The reduced expression levels of β-catenin, c-myc, cyclin D1 and GSK-3β suggested that the cherry extract performed its positive effect on UC by suppressing the Wnt/β-ctenin pathway. This finding may pave the way into further understanding the mechanism of cherry polyphenols ameliorating ulcerative colitis.
