“…The leaves of Corchorus olitorus and Hibiscus sabdariffa have high level of protein and could be used as food protein supplement. The fibre and carbohydrate contents of both the leaves of Corchorus olitorus and Hibiscus sabdariffa observed in this study were lower than reported values for a number of tropical plants [28]. It is reported that carbohydrate provides energy to the cells in the body, particularly the brain, which is the carbohydrate-dependent organ in the body [29].…”

Aims: Leafy vegetables play an important role as essential components of diet for rural populations in tropical Africa. The aim of this study was to evaluate the nutritive value of two leafy vegetable species (Corchorus olitorus and Hibiscus sabdariffa) consumed widely as sauces in Côte d'Ivoire. Methodology: The proximate composition, minerals, nutritive and anti-nutritional components of fresh leafy vegetables were determined according to standard methods for nutritional guidelines.

“…A decrease in absorbance at 734 nm was used to compute the antioxidant activity of the carotenoid samples, expressed as percentage of inhibition of the oxidation of ABTS * + . The antioxidant activity of SGH1 carotenoids was finally expressed as TEAC (Trolox equivalent antioxidant capacity) and IC 50 (concentration of carotenoids expressed as µg/ml, needed to scavenge 50% of ABTS * + ) (Re et al, 1999;Mandelli et al, 2012;Konan et al, 2016). Each independent experiment evaluated 4-5 different concentrations of antioxidant in assays in triplicate.…”

An extreme halophilic archaeon, strain SGH1, is a novel microorganism isolated from endolithic microbial communities colonizing halites at Salar Grande, Atacama Desert, in northern Chile. Our study provides structural, biochemical, genomic, and physiological information on this new isolate living at the edge of the physical and chemical extremes at the Atacama Desert. SGH1 is a Gram-negative, red-pigmented, non-motile unicellular coccoid organism. Under the transmission electron microscope, strain SGH1 showed an abundant electro-dense material surrounding electron-lucent globular structures resembling gas vacuoles. Strain SGH1 showed a 16S rRNA gene sequence with a close phylogenetic relationship to the extreme halophilic archaea Haloterrigena turkmenica and Haloterrigena salina and has been denominated Haloterrigena sp. strain SGH1. Strain SGH1 grew at 20-40 • C (optimum 37 • C), at salinities between 15 and 30% (w/v) NaCl (optimum 25%) and growth was improved by addition of 50 mM KCl and 0.5% w/v casamino acids. Growth was severely restricted at salinities below 15% NaCl and cell lysis is avoided at a minimal 10% NaCl. Maximal concentrations of magnesium chloride and sodium or magnesium perchlorates that supported SGH1 growth were 0.5 and 0.15M, respectively. Haloterrigena sp. strain SGH1 accumulates bacterioruberin (BR), a C 50 xanthophyll, as the major carotenoid. Total carotenoids in strain SGH1 amounted to nearly 400 µg BR per gram of dry biomass. Nearly 80% of total carotenoids accumulated as geometric isomers of BR: all-trans-BR (50%), 5cis-BR (15%), 9-cis-BR (10%), 13-cis-BR (4%); other carotenoids were dehydrated derivatives of BR. Carotenogenesis in SGH1 was a reversible and salt-dependent

“…According Yanishlieva et al (2006), free radicals and reactive oxygen species are involved in a variety of pathological events such as aging, inflammation, cancer, atherosclerosis, and diabetes. Then, regular consumption of C. olitorius, especially varieties having rounded and non-shiny leaves, elongated and shiny leaves, red stems or elongated and non-shiny leaves with lobed lateral, would be useful for the treatment of various diseases induced by free radicals as others traditional leafy vegetables such as Launeae taraxacifolia (Koukoui et al, 2015), Hibiscus sabdariffa, Solanum scabrum and Basella alba (Konan et al, 2016).…”

Corchorus olitorius L. which belongs to Tiliaceae family is a cultivated herbaceous plant highly consumed as traditional leafy vegetables in Benin. Extracts from samples of different morphotypes leaves of this species were analysed for their phytochemical compositions, antioxidant and cytotoxicity activities. On each sample extract, qualitative phytochemical tests were used to detect the presence of bioactive molecules and evaluate their cytotoxicity using brine shrimp lethality bioassay. Antioxidant activity was assessed using the 2,2-diphenyl-1-picryl-hydrazyl assay. Phytochemical screening revealed the presence of several phytochemical compounds in all samples of morphotypes studied but these have not a similar profile. Morphotypes with shiny rounded leaves have more phytochemicals (58% of phytochemicals compounds) than the other samples. Analysis of the potential antioxidant reveals a first category of morphotypes with high potential antioxidant capacity ranged from 27,859 to 32,985 mM EAA/g followed by second class of morphotype which ranged from 17,527 to 23,098 mM EAA/g . Regular consumption of C. olitorius such as varieties with rounded and non-shiny leaves, varieties with elongated and shiny leaves, varieties with red stems, varieties with elongated and nonshiny leaves with lateral lobes, would be useful for the treatment of various diseases induced by free radicals. The LC50 of morphotypes C. olitorius varies between 0.78 and 3.125 mg/ml indicating non toxicity. From this study, results justify the use of some morphotypes of C. olitorius in traditional medicine. Hence, these morphotypes are nutraceuticals leafy vegetables that must be promoted through development of food based products.
