use of the trolox assay to estimate the antioxidant content of seventeen edible Wild Plants of niger
Life Sciences, 1998Co-Authors: Julia A Cook, Dorothy J Vanderjagt, R S Glew, G Mounkaila, Amitava Dasgupta, Walter BlackwellAbstract:Abstract Although Wild edible Plants of the western Sahel and other parts of sub-Saharan Africa are consumed to some extent at all times of the year, greater amounts are consumed when cereal harvests are insufficient to support the populations living in these areas. The purpose of this study was to use a recently reported Trolox-based assay to measure the total antioxidant capacity of aqueous extracts of 17 Plants that we gathered from southern Niger. The antioxidant contents of the aqueous extracts were compared to those of spinach and potato. Of the 17 Plants, 11 had a greater antioxidant content than spinach and 14 had a greater antioxidant content than potato. The leaves of Tapinanthus globiferus had the greatest antioxidant content, and the fruit of Parinari macrophylla had the lowest. In general, leaves contained more antioxidants than either fruits or seeds. The total antioxidant capacity of the aqueous extracts was relatively high, indicating that the Wild Plants of the western Sahel may contain substantial amounts of water-soluble flavonoid glycosides, which are potent antioxidants and have been shown to have anticancer properties.

nutrient content of the edible leaves of seven Wild Plants from niger
Plant Foods for Human Nutrition, 1998Co-Authors: C Freiberger, Dorothy J Vanderjagt, Andrzej Pastuszyn, R S Glew, G Mounkaila, M MillsonAbstract:Wild Plants play an important role in the diet of the inhabitants of Niger. These Plants tend to be drought-resistant and are gathered both in times of plenty as well as times of need. Used in everyday cooking, famine foods may be an important source of nutrients. The goal of this study was to investigate the nutritional role of Wild Plants in the nigerien diet. To this end, leaves of seven Plants species were analyzed for their mineral, amino acid and fatty acid contents: Ximenia americana, Amaranthus viridus, Corchorus tridens, Hibiscus sabdarifa, Maerua crassifolia, Moringa oleifera, and Leptadenia hastata. Ximenia americana} contained large amounts of calcium. Large quantities of iron were present in Amaranthus viridus. All seven Plants contained significant amounts of selenium and phosphorus. Corchorus tridens contained the most protein (19–25% dry weight), and its composition compared favorably to the World Health Organization's standard for essential amino acids. Moringa oleifera contained 17% protein and compared favorably with the WHO standard. Corchorus tridens contained the largest amounts of the two essential fatty acids linoleic and α-linolenic acids. These results reinforce the growing awareness that Wild edible Plants of the Western Sahel can contribute useful amounts of essential nutrients, including amino acids, fatty acids and trace minerals, to human diets.

glucosinolates in sisymbrium officinale l scop comparative analysis in cultivated and Wild Plants and in vitro assays with t2rs bitter taste receptors
Molecules, 2019Co-Authors: Gigliola Borgonovo, Marta Guarise, N. Zimbaldi, F. Bedussi, M. Winnig, T. Vennegeerts, Angela BassoliAbstract:Sisymbrium officinale (L.) Scop., commonly known as “hedge mustard” or “the singer’s plant” is a Wild plant common in Eurasian regions. Its cultivation is mainly dedicated to herboristic applications and it has only recently been introduced into Italy. The active botanicals in S. officinale are glucosinolates, generally estimated by using UV or high-performance liquid chromatography (HPLC). Using both techniques, we measured the total glucosinolates from S. officinale in different parts of the plant as roots, leaves, seeds, and flowers. A comparison was made for cultivated and Wild samples, and for samples obtained with different pre-treatment and fresh, frozen, and dried storage conditions. Cultivated and Wild Plants have a comparable amount of total glucosinolates, while drying procedures can reduce the final glucosinolates content. The content in glucoputranjivin, which is the chemical marker for glucosinolates in S. officinale, has been determined using HPLC and a pure reference standard. Glucoputranjivin and two isothiocyanates from S. officinale have been submitted to in vitro assays with the platform of bitter taste receptors of the T2Rs family. The results show that glucoputranjivin is a selective agonist of receptor T2R16.

edible and tended Wild Plants traditional ecological knowledge and agroecology
Critical Reviews in Plant Sciences, 2011Co-Authors: Nancy J Turner, łukasz łuczaj, Paola Migliorini, Andrea Pieroni, Angelo Leandro Dreon, Linda E Sacchetti, Maurizio G PaolettiAbstract:Humans the world over have depended on Wild-growing Plants in their diets for hundreds of thousands of years, and many people continue to rely on these species to meet at least part of their daily nutritional needs. Wild harvested plant foods include: roots and other underground parts; shoots and leafy greens; berries and other fleshy fruits; grains, nuts and seeds; and mushrooms, lichens, algae and other species. Use of any of these species requires special cultural knowledge regarding harvesting, preparation, cooking and other forms of processing. Many were, and are, prepared and served in mixtures or combinations. In most cases, too, the species are managed, tended or manipulated in some way to increase their productivity and availability. Many of the most widely used species are categorized as weeds—species that grow and reproduce readily in disturbed or cleared land, and are common around human settlements and agricultural areas. This paper presents case examples of edible Wild plant use and the role...

phenolic compound production in relation to differentiation in cell and tissue cultures of larrea divaricata cav
Plant Science, 2012Co-Authors: Lorena Palacio, Juan Jose Cantero, Rosa M Cusido, Marta GoleniowskiAbstract:The lignan nordihydroguaiaretic acid (NDGA) and its derivatives existing in Larrea divaricata species show a wide range of pharmacological activities which makes this genus an interesting target to consider the plant in vitro cultivation systems as a feasible alternative source for their production. These compounds are potentially useful in treating diseases related to heart condition, asthma, arteriosclerosis, viral and bacterial infections, inflammation and cancer. In the present study, calli, cell suspension cultures, and in vitro and Wild Plants of L. divaricata were investigated for their potential to synthesize phenolic compounds. Calli, both with and without organogenesis, produced NDGA and quercetin, as did plantlet and Wild Plants. NDGA was also produced by the cell suspension cultures, together with p-coumaric acid, ferulic acid and sinapyl alcohol. The capacity of undifferentiated tissues to form phenolic compounds is very limited, but when the calli underwent organogenesis, developing mainly adventitious shoots, the phenolic compound production increased significantly. Plantlets regenerated from adventitious shoots of L. divaricata calli did not show the same phenolic pattern as Wild Plants, with levels of NDGA and quercetin being 3.6- and 5.9-fold lower, respectively.
