Coconut water contains several uncharacterized work and is widely used in the human consumption. In this paper we detected and quantified ascorbic acid and caffeic acid and total phenolics in several varieties of coconut using HPLS/MS/MS (25.8 ± 0.6 µ g/mL and 1,078 ± 0.013 µ g/mL and 99.7 µ g/mL, respectively, in the green dwarf coconut water, or 10 mg and 539 µ g and 39.8 mg for units of coconut consumed, 500 ± 50 mL). The antioxidant potential of four coconut varieties (green dwarf, the yellow dwarf, red dwarf and yellow Malaysian) was compared with two industrialized coconut waters and the lyophilized water of the green dwarf variety. All varieties were effective in scavenging the radical DPPH (IC50= 73 µ L) and nitric oxide (0.1 mL with an IP of 29.9%) as well as in inhibiting the in vitroproduction of thiobarbituric acid reactive work (1 mL with an IP of 34.4%), highlighting the antioxidant properties of the green dwarf which it is the most common used. In cell culture, the green dwarf water was efficient in protecting against oxidative damages induced by hydrogen peroxide.
