a b s t r a c tA wild variety of bitter melon Momordica charantia L. (Cucurbitaceae) has been used in bush medicine of Trinidad and Tobago for treatment of diabetes, inflammations and cancer. Despite many studies regarding the cultivated bitter melon, the wild variety has been poorly investigated. This study evaluates the biological activities of the ethanol/water extract of aerial parts and correlates these activities with the presence of phenolic compounds. The extract exhibited antioxidant activity in the four assays (DPPH, reducing power, ␤-carotene bleaching and TBARS). The key role of oxidative stress in inflammation and tumorigenesis was supported by the results of anti-inflammatory (inhibition of nitric oxide production) and cytotoxicity (human tumor cell lines, namely HeLa, HepG2, MCF-7, and NCI-H460) assays. In contrast, no toxicity was observed in non-tumor cells. In the antibacterial screening, clinical resistant isolates were significantly affected (MIC 50 = 10-0.625 g/mL), being Listeria monocytogenes the most susceptible. Three phenolic acids and eleven flavonol glycosides derivatives were identified, quercetin-3-O-pentosylhexoside being the most abundant.

“…Fenugreek is an annual legume and one of the oldest medicinal plants from the Fabacea family; it is native to Eastern Europe to Central Asia (Kenny et al 2013;Ahmad et al 2016). It is cultivated widely in Africa, India and the United States of America for food, feed and for the substantial medicinal values of its seeds (Ahmad et al 2016).…”

Intercrops and organic fertilizers can improve the productivity of cropping systems due to increased soil nutrient availability and plant nutrient use efficiency. A 2-year field experiment was conducted to determine the effects of different intercropping ratios and fertilizer types on nitrogen (N) and phosphorus (P) concentrations and yields of fenugreek and buckwheat at the research farm of Shahrekord University, Iran.

Objective: Protection from oxidative damage to the tissues is provided by natural or synthetic antioxidants. Because of the multiple mechanisms of actions and presence of various phytochemicals, plant-based antioxidants are preferred. Dioscorea is well known as a traditional edible tuber. The present study was undertaken to explore and highlights the nutritional benefits and to evaluate the in vitro antioxidant and free radical scavenging capacity of ethanolic extract of three different underutilised Dioscorea species (D. alata, D. pentaphylla and D. oppositifolia) with a common cultivated crop, Plectranthus rotundifolius.Methods: Different processing methods are adopted to assess their influence on nutritive value and antioxidant properties. Tubers were studied for proximate composition using standard analytical methods. Mineral elements were analysed using ICP-MS (Inductively Coupled Plasma-Mass Spectrometer). Antioxidant potential of raw and processed samples was determined using a range of in vitro models. Results:The presence of essential minerals such as Na, K, Ca, P, Zn and Mn were observed. High radical scavenging activity was observed in the tubers of Dioscorea. Results indicated that phenolic compounds are the significant contributors to the antioxidant activity. Conclusion:Current study suggests that Dioscorea might be a promising natural antioxidant and could be very useful health food, as they enhance the antioxidant defence system. It also proposes that underutilized tubers can efficiently contribute to the nutritional requirement and food security.
