Comparative Examination of Phytonutrients and Antioxidant Activity of Commonly Consumed Nuts and Seeds Grown in Vietnam

The aim of the present study was to determine phenolics, carotenoids, B-vitamins, and antioxidant activity nuts seeds grown in Vietnam. concentrations carotenoids B-vitamins may vary among seeds. Watermelon seed contained highest level lutein while pumpkin β-carotene richest sample. Sachi inchi sunflower comprised considerable levels vitamin B1, B6, B9. phenolic analysis revealed that cashew total amount flavonoids (466.04 μg/g), with catechin, epicatechin, procyanidin B2 predominating over other flavonoids. Likewise, chlorogenic neochlorogenic acids made up (1870.41 μg/g). Walnut appeared possess evaluated by DPPH, ABTS, FRAP, reducing power assays. correlation indicated strong positive correlations between content DPPH FRAP values. Principal component graphically showed distant positioning seed, highlighting their significantly higher phenolics. findings would be useful improve nutrient database contents for as well promote consumption nut products
