Cucumis Melo L

Introduction and Aim: Cucumis melo L. commonly known as wild melon (in English) belongs to the family Cucurbitaceae and well distributed in rural areas. Cucumis melo L. is a annual climbing or perennial herb, distributed almost throughout India and neighbouring countries.  Nowadays food wastes are a major concern. On the other hand, the demand for natural valuable compounds to human health is increasing. These by-products contain phytochemical compounds with great nutritional and functional potentials. The fruits of this plant possess the abortifacient property and have antitussive, antioxidant, digestive, cytotoxic and anti-inflammatory properties.   Materials and Methods: The ethanolic extract was used to determine the antioxidant scavenging activity using DPPH method, protein denaturation for anti inflammatory studies, as well as in vitro cytotoxic activity by brine shrimp lethal assay (BSLA).   Results: The results obtained indicated highest antioxidant activity as compared to DPPH methods. The protein denaturation test showed the ethanolic extracts of Cucumis melo L. had effective anti-inflammatory activity. Extracts of Cucumis melo L. also registered potential cytotoxic activities by BSLA. This study provides the basis for further investigation of Cucumis melo L. for potential identification of novel bioactive compounds with therapeutic properties.   Conclusion: The presence of phytoconstituents such as flavonoids, terpenoids, alkaloids, may indeed assist to the antioxidant activity of fruit extract. That this next thing that must be done will be to conduct in vivo experiments and discern the histopathological mechanism.

Cytotoxicity is the quality of being toxic to cells, and in vitro cytotoxicity testing procedures reduce the use of laboratory animals. The present study was designed to investigate the cytotoxic activity of the Cucumis melo (L) fruit against HepG2 cell lines. To prepare the extract, fresh pulps of Cucumis melo fruit was chopped into pieces and dried at room temperature for 24 hours. 10 g of the dried fruit powder was successively extracted with 100 ml of ethanol using Soxhlet apparatus and filtered through Whatman No 1 filter paper. The cytotoxic activity for cancer cell lines was evaluated by MTT assay. The in vitro cytotoxicity of different concentrations (18.75 - 300μg/mL) of the ethanolic extract of Cucumis melo fruit was evaluated by the MTT assay. The IC50 value is measured by the concentration of extract, causing 50% growth inhibition of cancer cells. The results indicated that the cytotoxic effect of the ethanolic extract of Cucumis melo fruit against HepG2 cells is dose-dependent. At low concentrations, the extract was found to be less toxic towards the HepG2 cells, whereas, at higher concentrations, the toxicity was increased. The concentration at 201.5 µg / ml was found to be an effective dose because, at this concentration, it exhibited 50 % cytotoxicity against HepG2 cells. This work revealed the potentials of ethanolic extract of Cucumis melo fruit as a cytotoxic agent against liver cancer cell lines. The plant can be further screened against various diseases using toxicity models in order to find out its unexplored efficacy.

The antioxidant potential ofActinidia macrospermaC. F. Liang (Actinidiaceae) was investigated in vitro for total phenolic content, along with total antioxidant activity (TAA), 1,1-diphenyl 2-picryl hydrazyl (DPPH), and lipid peroxidation (LP). The results indicated that different polarity extracts ofA. macrospermaexhibit different biological activities, which depends mainly on the presence of phenolic compounds. The antioxidant activity was in the following decreasing order: MeOH extract > EtOAc extract > aqueous extract > CHCl3extract > Hexane extract. Moreover, the cytotoxic activity of this plant by MTT dye assay using SMMC-7721 has been determined also. The hexane, EtOAc, and CHCl3extracts showed cytotoxicity in a dose-dependent manner. Methanol and aqueous extracts, however, showed weak activities in this test. And a very significant cytotoxic activity, not significantly different from the positive control of quercetin, was observed in CHCl3extract.

Euphorbia hirta L (Euphorbiaceae) also called asthma herb has long been prescribed in traditional medicine because it exhibits diverse pharmacological actions due to the presence of alkaloids, flavonoids, polyphenols, triterpenoids, and saponins. The present study is aimed at the study of phytochemical and antioxidant activity and anti-inflammatory screening of E. hirta. Extraction of dried powder was performed followed by phytochemical screening using color reactions. Total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were estimated by Folin-Ciocalteu and Aluminum chloride method respectively. The antioxidant activity was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method.  Anti-inflammatory activity was studied by using protein denaturation in vitro bioassay. Phytochemical screening showed the presence of flavonoids, alkaloids, and phenolic compounds. TPC, TFC and antioxidant activity (IC50) of the extract were found as 288.10 mg gallic acid equivalent per gram (GAE/g), 29.36 mg quercetin equivalent per gram (QE/g) and 32.23 µg/mL (p<0.05) respectively. Diclofenac sodium and E. hirta extract showed the maximum inhibition of 91.28% and 68.20% respectively at the concentration of 1000 µg/mL compared with control (p>0.05). The phenolic compounds and flavonoids exert antioxidant and anti-inflammatory activities because of their scavenging ability. The demonstrated antioxidant and anti-inflammatory activities may be the rationale behind some of its folkloric uses and also may be responsible for some of its pharmacological effects. Thus, E. hirta can be considered a good source of antioxidants and anti-inflammatory actions, which might be beneficial for combating oxidative stress.
