Antioxidant activity and polyphenol content in edible wild fruits from Nepal

Abstract

Fifteen fruits commonly used by the ethnic population in Nepal were studied for the antioxidant activity and total polyphenol content (TPC). Among them, Terminalia bellirica, Terminalia chebula, Phyllanthus emblica and Spondias pinnata were the most potent antioxidants as compared with vitamin C based on the 1,1-diphenyl-2-picryl hydrazyl radical assay. These fruits also contained high TPCs. Spondias pinnata, Pyrularia edulis, Melastoma malabathricum, Cipadema bacifera and Choerospondias axillaries fruits were evaluated for the first time. Moreover, Spondias pinnata was found to be more potent (16% radical scavenging activity at 5 microg/ml) than vitamin C (5% radical scavenging activity at 5 microg/ml). Antioxidant activity showed correlation to TPC with the correlation coefficients (R(2)) as 0.7189 and 0.7246 for the methanol and water extracts, respectively. This study suggests that a number of these fruits may have the potential to confer beneficial health effects due to their antioxidant activity and TPC.

Phyllanthus emblica L. Branch Extract Ameliorates Testicular Damage in Valproic Acid-Induced Rats

“…Unfortunately, this study did not show those results; however, such biochemical analyses must be further investigated to elucidate the real mechanism underlying of PE protective effects. It can be clearly explained that PE extract used in this study is rich in phenolic contents and antioxidant capacities (Iamsaard et al, 2014b), which is similar to those of the fruit parts (She et al, 2013;Chalise et al;Sawant et al, 2010). Indeed, PE extract did not affect any male reproductive organs including sperm parameters as compared to the control.…”

“…Focusing on the fruit, it has been demonstrated that the fruits of PE are rich in phenolics (She et al, 2013) and possess antioxidant activities (Chalise et al, 2010;Sawant et al, 2010). In addition, PE fruits have been proven to have many therapeutic properties (Krishnaveni and Mirunalini, 2010;Chularojmontri et al, 2013).…”

Phenolic extracts of Centaurium erythraea with novel antiradical, antibacterial and antileishmanial activities

“…These molecule groups have showed other pharmacological activities such as a mitochondrial adhesion inhibitor, an antiulcer, an anti-arthritic, an antiangiogenic and an anticancer agent [40]. Furthermore, some studies have established the correlation link between the consumption of these molecules and prevention of some diseases such as oxidative stress related diseases, chronic inflammation, immune related diseases, diabetes and cancer [41].…”
