Phenolic content, antioxidant activity and effective compounds of kumquat extracted by different solvents.[Pubmed:26616917]
Food Chem. 2016 Apr 15;197(Pt A):1-6.
The total phenolic and flavonoid content of extracts from peel of kumquat were higher than those from pulp, and those extracted from immature kumquat were higher than those from mature kumquat. The highest levels of phenolic and flavonoid content were obtained in hot water extracts. The flavonoids of kumquat extracted from hot water were mainly soluble conjugated compounds, including C-glycosides, such as 3',5'-di-C-beta-glucopyranosylphloretin (DGPP), acacetin 8-C-neohesperidoside (margaritene), acacetin 6-C-neohesperidoside (Isomargaritene), apigenin 8-C-neohesperidoside, and O-glycosides, such as acacetin 7-O-neohesperidoside (fortunellin), isosakuranetin 7-O-neohesperidoside (poncirin) and apigenin 7-O-neohesperidoside (rhoifolin). A positive relationship existed between total phenolic content and DPPH scavenging potency (p<0.001). Total flavonoid content showed a similar correlation (p<0.001) to DPPH scavenging potency. The effective flavonoids contributing to antioxidant activity were DGPP and apigenin 8-C-neohesperidoside, which could be extracted in high amounts, by hot water at 90 degrees C, from immature kumquat peel.
Drying effect on flavonoid composition and antioxidant activity of immature kumquat.[Pubmed:25308680]
Food Chem. 2015 Mar 15;171:356-63.
A seven flavonoids in hot water extract of immature kumquat (Citrus japonica var. margarita) were identified and quantified (mg/100g fresh fruit): 3',5'-di-C-beta-glucopyranosylphloretin (DGPP, 285.9 +/- 2.9 mg/100g), acacetin 8-C-neohesperidoside (margaritene, 136.2 +/- 2.6 mg/100g), acacetin 6-C-neohesperidoside (Isomargaritene, 119.1 +/- 1.8 mg/100g), fortunellin (acacetin 7-O-neohesperidoside, 28.5 +/- 0.7 mg/100g), apigenin 8-C-neohesperidoside (16.9 +/- 0.1mg/100g), poncirin (isosakuranetin 7-O-neohesperidoside, 5.1 +/- 0.1mg/100g), and rhoifolin (apigenin 7-O-neohesperidoside, 2.0 +/- 0.1mg/100g). When immature kumquat was dried at 110 and 130 degrees C for 0.5h, the antioxidant activity, total phenolic content and identified flavonoids increased. The UV absorbance of browning products of immature kumquat dried at 130 degrees C for 1.5h increased dramatically, while the identified flavonoids decreased. Therefore, it was concluded that drying below 130 degrees C for 1.0 h, could release phenolic compounds, which resulted in the increasing antioxidant activity. Drying at 130 degrees C for 1.5h, it might be due to the effect of formed browning products.
