Nutritional Composition, Antioxidant and Antimicrobial Activities of Selected Wild Edible Plants

Background:The two wild plants viz. Sphenoclea zeylanica and Sphaerantus peguensis are seasonally consumed as vegetables by the Bodo people in Assam of North East India. Wild vegetables are considered as one of the cheapest sources for human nutrition that contains rich sources of numerous minerals and bioactive compounds which on consumption can contribute several health benefits against various diseases.Objective:The aim of the present study is to investigate amino acid profiles, antimicrobial property and anti-nutritional contents of the two wild edible plants.Methods:Amino acid profiles were determined by using ultra-performance liquid chromatography, antimicrobial activities of aqueous and methanol extracts of the plants were tested following the disc diffusion method against Bacillus cereus, Staphylococcus aureus, Proteus vulgaris and Escherichia coli, and anti-nutritional contents were evaluated based on the reported methods.Results:The total amino acid content found in S. zeylanica was 42.87 mg/g dry weight and it was found to be 32.65 mg/g dry weight in S. peguensis. The methanol extracts of the plants are exhibiting antibacterial activities against all the studied microorganisms. However, aqueous extracts showed no antibacterial activity against P. vulgaris and B. cereus. In this study, S. zeylanica species showed higher levels of anti-nutritional contents compared to S. peguensis.Conclusion:In the study, higher levels of essential amino acids were detected in S. zeylanica compared to S. peguensis. The methanol extracts of the plants showed more effective antimicrobial activities in comparison to the aqueous extracts and this may be due to the presence of antimicrobial compounds which are more readily soluble in methanol.

Antioxidant And Antimicrobial Activities

Garlic (Allium sativum L.) has been used worldwide not only for its being a subject of dietary interest, but also for medicinal purposes, in prophylaxis, and for the treatment of diverse pathologies. New processing techniques have been developed and placed on the market in recent years to improve the organoleptic and nutritional value of food products. The present work aimed to study bulbils (cloves) of white (commercial and traditionally cultivated samples with different proveniences) and black (processed samples) garlic. All samples were compared with regard to their nutritional composition as well as their antioxidant and antimicrobial activities. Black garlic had the lowest moisture content but the highest total amount of sugars and energetic value. Black garlic also presented the highest antioxidant and antimicrobial (especially against methicillin-resistant Staphylococcus aureus) activities. Thus, black garlic, obtained by processing techniques, can be considered a promising product with high value that will be able to be exploited by the functional food/nutraceutical industry.

Abstract Abstracts Background: Locally available and easily accessible, underused complementary foods including wild edible fruit species are affordable and potentially more acceptable than other options to address the problem of ‘hidden hunger’ or micronutrient deficiency. Study aimed to collect and determine the nutritional composition of wild edible fruits with its bioavailability collected from Temcha watershed. Methods: Semi structured interviews were administered to collect all wild edible plants and its associated knowledge through the participation of informants systematically selected from six sub districts in the study area. Mineral and pyhtate content and molar ratio of phytate to mineral ratio were determined using standard methods. Results: Based on the total use value of all wild edible plants, the top 18 wild edible fruits were selected for dietary analysis. The zinc contents of the analyzed fruits were ranged in between 0.06 ± 0.02 mg/100g -88.89 ± 0.42 mg/100g. The iron content of the analyzed fruits were ranged in between 5.84 ±0.00 mg/100 g – 148 ± 0.93 mg/100g and the calcium contents were in between 53.25 ± 0.45 mg/100g – 1280 ± 0.77 mg/100g. The phytate content of each fruits were ranged in between 6.9 ± 0.00 mg/100g – 51.4 ± 0.04 mg/100g. Conclusions: Combination of Ficus sycomorus and either of all wild edible fruits satisfy the daily-recommended allowance of calcium for male and female age 10-18 (1300 mg/100 g). Almost all WEFs provides optimum amount of iron for Children up to 10 years required 11.6 – 17.8 mg / day except Embelia schimperi, Ficus sur, Rossa abyssinica, Rubus studinary & Ximenia americana. The different amount of zinc (0.66 - 89 mg /100 g) contributes to control progressive stunting in children in the study area. The phytate concentrations of wild edible fruits do not have a negative impact on the bioavailability of calcium, iron and zinc. The micronutrient content of wild edible fruits provided a lot of contribution for the study area communities and those who shared similar feeding culture elsewhere in the country.

Wild Edible Fruits

The United Nations adopted the Millennium Declaration of September 2009 to improve the global living conditions through reducing poverty and hunger. However, considerable numbers of people are still living in utter penury and are deprived of a dignified living. In such tough circumstances natureâ€™s free gift in the form of wild edible foods are benefiting the vulnerable and dependent communities. Wild edible plants (WEPs) are the species those are neither cultivated nor domesticated however are available in their wild natural habitat and used as sources of these plants have played a significant role in the development and civilization of human history throughout the ages and globe. These wild edible plants have played a significant role in supplying food and nutritional requirements of poor communities in many rural parts of the world. These wild edibles can be popularized only when they are comparedfor their nutritional and health benefits with major or widely used cultivated plants. The social, cultural, religious, and belief system of the rural communities are incomplete without these wild edible plants. Domestication of these wild edible plants can increase their use and their conservation as well. The present review paper has described the wild edible plants in context of their diversity, traditional knowledge, conservation practices and nutritional composition from the available secondary literature. Authors feel there is still scope to incorporate more contextual variables for explaining more variations embedded with local peopleâ€™s perception on values and usage of these wild edible fruits.
