Abstract

|
|
The study investigated the chemical components, antioxidant activities, and glucose-regulating enzyme activities of red chicory (Cichorium intybus L.). On a dry weight the contents of moisture, crude protein, crude fat, crude ash, crude fiber, and carbohydrate were 7.36, 28.0, 4.33, 19.63, 10.84 and 40.52%. The contents of mineral were Na (772.39 mg/100 g), K (5,686.03 mg/100 g), Mg (307.48 mg/100 g), Ca (804.94 mg/100 g), Fe (8.61 mg/100 g), and P (1,145.24 mg/100 g). Chlorophyll a, Chlorophyll b, total chlorophyll (793.80, 363.06, 1,156.86 mg/100 g,), total carotenoid (171.82 mg/100 g), and anthocyanin (79.49 mg/100 g) contents were measured. Antioxidant activities were analyzed for water and 70% ethanol extract. The polyphenol contents 23.67, 32.58 GAE mg/g, and flavonoid contents were 18.15, 28.76 RE mg/g, respectively. The DPPH scavenging activity IC50 was 694.48, 76.12, μg/mL, and the ABTS scavenging activity IC50 1,154.90, 566.00 μg/mL, respectively. In reducing power, the 70% ethanol extract showed a higher reducing power. In α-glucosidase and α-amylase inhibition activity IC50, the 70% ethanol extract (5.87, 17.91 mg/mL, respectively) showed a higher than water extract (8.87, 100 < mg/mL, respectively).
This study is expected to provide basic data for developing functional food ingredients for red chicory.
