  The objective of present study was to evaluate the therapeutic potential of Cucumis melo seeds traditionally consumed and it was studied for free radical scavenging potential by hydrogen peroxide (H2O2) and DPPH method. Anti-inflammatory activity was evaluated using carrageenan-induced paw edema in rats. Analgesic activity was evaluated by tail immersion and tail flick methods in mice. The percentage scavenging of DPPH radical and H2O2 radical was 74.9% at 300 μg mL-1 and 58.91% at 200 μg mL-1 respectively concentration of. The H2O2 scavenging effect of MECM was 58.91%. The percentage reduction of paw edema was 56.6% at the dose of 300 mg kg-1. The high dose caused significant reduction in pain. Thus it can be concluded from the above results that Cucumis melo seeds have potent anti-inflammatory, antioxidant and analgesic activity.

  The present study was designed to evaluate the antioxidant and anti-ulcerogenic potential of Citrus karna peel extract. Extraction of Citrus karna peels was carried out using different solvents. Phytochemical screening and evaluation of antioxidant activity of all the extracts were carried out. Further, anti-ulcerogenic activity of ethyl acetate extract of Citrus karna peels (EtCK) was assessed in water immersion (WIS) and hypothermic restraint (HRS) stress models at different doses (200, 300 and 400 mg kg-1). EtCK showed ulcer protective effect in both models in a dose dependent manner, which was indicated by decrease in the ulcerative index and thiobarbituric acid reactive species (TBARS) level in the blood and gastric tissue samples as compared to the disease control group. Moreover, antioxidant markers i.e., reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) in the blood and tissue samples were found to be significantly increased in medium and high doses of EtCK (300 and 400 mg kg-1) treated groups similar to that of ranitidine treated group. The present study concluded that EtCK has a significant anti-ulcer effect at a dose level of 300 and 400 mg kg-1. Hence, it may be considered as a useful herbal therapeutic agent for the treatment of peptic ulcer disease.

  The present study was to investigate the anti-ulcer activity of methanolic extract of Cucumis melo (MECM) seeds. The seeds were extracted with methanol and the extract was evaluated for its free radical scavenging activity by DPPH. It shows maximum antioxidant activity. Thus extract was further evaluated against gastric ulcerations by Pyloric Ligation (PL), Water Immersion Stress (WIS) and NSAID (indomethacin) induced ulcer (NIU) models. In case of PL method, the extract inhibited gastric ulcerations in a dose-related manner (150 and 300 mg kg-1). Then it was evaluated for gastric volume, free acidity, total acidity, ulcerative index. The ulcerative index was also measured in WIS model and NIU with same doses. The MECM caused 57.6, 67.6 and 61.9% inhibition of ulcers in pyloric ligation, water immersion stress, NSAID induced ulcer models respectively at 300 mg kg-1. The results concluded that MECM possess high antiulcer potential which is due to its higher antioxidant activity.

  The present study was designed to investigate Cucumis melo var. utilissimus seeds for their antioxidant and therapeutic potential. The antioxidant activity of methanolic extract was measured by DPPH method and hydrogen peroxide free radical scavenging activity. The methanolic extract of Cucumis melo var. utilissimus seeds (MECU) showed maximum antioxidant potential. Hence, it was further evaluated for anti-inflammatory activity by carrageenan induced rat paw edema and analgesic activity by tail immersion method and tail flick method at different concentrations, i.e., 100, 200 and 300 mg kg-1. The significant results was found at maximum dose. The results suggested that methanolic seed extract possess great therapeutic potential.

  In the present study free radical scavenging and antiulcer potential of Benincasa hispida seeds was evaluated. The powdered seeds were extracted with methanol. The extract was evaluated for its free radical scavenging activity by DPPH method followed by antiulcer activity using pyloric ligation, water immersion stress and NSAID (indomethacin) induced gastric ulcer model (NIU) in rats. The parameters assessed were gastric volume, free acidity, total acidity, ulcer index and percentage ulcer protection. Ranitidine was used as the reference antiulcer drug. The methanolic extract showed concentration dependent DPPH radical scavenging activity. The methanolic extract of Benincasa hispida seeds (MEBH) inhibited gastric ulceration by decreasing the gastric volume, free and total acidity. The high dose (300 mg kg-1) showed significant reduction in the above parameters which was comparable to the standard drug ranitidine (p<0.05). The MEBH caused 52.7, 67.4 and 61.2% inhibition of ulcers in pyloric ligation, water immersion stress and NSAID induced ulcer models, respectively at 300 mg kg-1. Thus it can be concluded that the seeds of Benincasa hispida possess potent antiulcer activity. The antiulcer action may be exerted through free radical scavenging mechanism.
