AbstractBackground:Mill. is an ethnomedicinal plant and its fruit has been traditionally used by Puliar tribes of Anamalai Hills, Tamil Nadu, India to treat various ailments. Phytochemical analysis, antioxidant, cytotoxic and inducible nitric oxide synthase (Methods:To explore bioactive compounds present in the ripened fruits, high-performance thin-layer chromatography (HPTLC) and gas chromatography/mass spectrometry (GC–MS) analysis were done. Free radical scavenging, hepatoprotective, inhibition ofResults:Total flavonoid content of ZOFwas estimated as 69 µg/mg catechin equivalent. HPTLC densitogram confirmed the presence of quercetin and GC–MS analysis showed a total of 16 compounds of 87.66 % with quinic acid as a major compound which accounted for 22.29 %. Free radical-scavenging activity of ethanolic fruit extract was ranged from 160.12 to 650.23 µg/mL. An amount of 1.5 µg lipopolysaccharide (LPS)- induced severe inflammation in BALB/c mice liver, followed by treatment with ethanolic fruit extract of 100 µg concentration, exhibited significant hepatoprotection and reverse transcriptase polymerase (RT-PCR) analysis showed downregulation ofConclusions:Findings of the present study prove that ZOF is a rich source of bioactive compounds with a wide range of pharmacological activities. Hence, consumption of this wild edible fruit will be a cost-effective and easily available natural nutritional source for health protection.

Glucolesquerellin (2), glucohesperin (3), quercetin 3-O-sophoroside (4), and quercetin 3-O-sophoroside-7-O-glucoside (5), isolated from the fruit of Dithyrea wislizenii , were quantified by HPLC. The fruit extract and flavonoids were not found to be toxic by using a brine shrimp lethality assay. The fruit extract and the flavonoids and glucosinolates were submitted to a free-radical scavenging activity assay with the diphenylpicrylhydrazyl radical (DPPH•). The concentration of quercetin (6) (a positive control for the flavonoids) able to scavenge 50% of DPPH• (SC50) was 32 ± 2 µmol/L (or 4 ± 1 µg/mL), which was about 27 times more potent than the crude extract. Compounds 4 and 5 had a SC50, the concentration of the compound required to scavenge 50% of the DPPH•, of 78 ± 1 µmol/L and 113 ± 10 µmol/L, respectively. The positive control for the glucosinolates, glucoraphasatin, (1) had a SC50 of 1768 ± 60 µmol/L. The glucosinolates 2 and 3 had a SC50 of 7819 ± 1968 and 970 ± 63 µmol/L, respectively.

The human body has an elaborate antioxidant defence system. Antioxidants are manufactured within the body and may even be extracted from the food like fruits, vegetables, seeds, nuts, meats and oil. Fresh fruits and vegetables are a rich source of antioxidant vitamins such as A, C and E, that prevent cellular damage associated with many diseases. This present investigation was designed to evaluate the radical scavenging activity of ethanolic extract of Cucumis melo fruit. The in vitro free radical scavenging effect of the Cucumis melo (L) fruit extract was assessed by using 1,1 – diphenyl 2-picryl hydrazyl radical (DPPH), ABTS (2, 2’-Azinobis (3-ethyl Benz Thiazoline-6-Sulfonic acid) hydroxyl radical, reducing power and nitric oxide scavenging assay. The scavenging activity of the fruit extract was tested at different concentrations. C.melo fruit extract showed concentration dependant free radical scavenging activity. Ethanol extract of Cucumis melo fruit (EECMF) exhibited maximum scavenging activity against DPPH (64.46%), ABTS (70.52%) hydroxyl radical (62.57%), and nitric oxide (61.18%) in comparison with standard antioxidants. The reducing power of ethanol extract of C.melo fruit was found to be 0.11 at 0.2mg/ml and increased to 0.49 at 1mg/ml. These results clearly indicate that ethanolic extract of C.melo fruit has great potential of free radical scavenging activity and it may be used as a bioactive source of natural antioxidants for pharmacology of functional foods.
