Abstract

Objectives

Neera, non-fermented coconut inflorescence sap (NFCIS) and its fermented form, toddy (FCIS) are the two well-known traditional drinks in South India. Both the saps show high rejuvenation effect and NFCIS is used for the curing of bronchial suffocation, anemia, tuberculosis and piles in traditional medicine. But, a few scientific studies have been reported on their health benefits so far. Presently, the antioxidant effect of both non-fermented (NFCIS) and fermented form (FCIS) of coconut inflorescence were analyzed in experimental animals.

Methods

The free radical scavenging property of FCIS and NFCIS was analyzed in vitro. The effect of these saps on mitigating sodium fluoride (NaF) deteriorated redox status was evaluated in mice.

Results

NFCIS exhibited high antioxidant activity than its fermented form. NFCIS reduces metal ions and scavenge hydroxyl and DPPH radicals with IC50 values 6.5 ± 1.9 and 44 ± 3.14 µL/mL, respectively. Supplementation of NFCIS for 14 days increased SOD, CAT and GPx activities and GSH level in liver by 51.67, 52, 27.88 and 35.77%, respectively against NaF induced decline with a concomitant decrease in lipid peroxidation to 40.76%. Saps rich in minerals indicate pharmaceutical and nutritional value.

Conclusion

The study revealed the antioxidant efficacy of non-alcoholic natural drink, Neera and recommends an alternative for synthetic carbonated soft drinks. The regular consumption of Neera may protect the body from various chronic diseases especially where the oxidative stress played as a key role.
