Underutilised fruits of Agasthyamala Biosphere Reserve: a potential source of natural antioxidants


Antioxidant properties of commercial fruits are well investigated however there is little information available about such properties of underutilised fruits. The present study evaluated the antioxidant potential of ten underutilised edible fruits viz., Aporosa cardiosperma (Gaertn.) Merr., Baccaurea courtallensis (Wight) Müll.Arg., Elaeocarpus serratus L., Flacourtia montana J. Graham, Phoenix loureiroi Kunth, Psidium guineense Sw., Spondias pinnata (L.f.) Kurz, Syzygium cumini (L.) Skeels, Syzygium gardneri Thwaites and Syzygium zeylanicum (L.) DC. from the Kerala part of Agasthyamala Biosphere Reserve. Total phenolic content was determined through Folin–Ciocalteau method, flavonoids by aluminium chloride colorimetric method, ascorbic acid by titrimetric method and antioxidant activity was measured by DPPH radical scavenging assay. Free radical scavenging potentials of the evaluated underutilised fruits were found to be proportional to their respective phenolic, flavonoid and ascorbic acid contents. Amongst all the fruits analysed, Elaeocarpus serratus L., Psidium guineense Sw., Syzygium gardneri Thwaites and Baccaurea courtallensis (Wight) Müll.Arg. exhibited significantly high antioxidant activity and can be explored as viable source of natural antioxidants for functional food and pharmaceutical applications.
