“…Since the 1975 publication by the US National Academy of Sciences of The Winged Bean: A High Protein Crop for the Tropics 6 , considerable effort has been focused on studying the nutritional quality and climatic and ecological tolerances of the plant 7 8 . Winged bean reportedly possesses anti-nutritional factors such as phytoglutenins, cyanogenic glycosides, tannins, lectins, flatulence factors, and saponins 9 .…”

Winged bean, Psophocarpus tetragonolobus (L.) DC., is similar to soybean in yield and nutritional value but more viable in tropical conditions. Here, we strengthen genetic resources for this orphan crop by producing a de novo transcriptome assembly and annotation of two Sri Lankan accessions (denoted herein as CPP34 [PI 491423] and CPP37 [PI 639033]), developing simple sequence repeat (SSR) markers, and identifying single nucleotide polymorphisms (SNPs) between geographically separated genotypes. A combined assembly based on 804,757 reads from two accessions produced 16,115 contigs with an N50 of 889 bp, over 90% of which has significant sequence similarity to other legumes. Combining contigs with singletons produced 97,241 transcripts. We identified 12,956 SSRs, including 2,594 repeats for which primers were designed and 5,190 high-confidence SNPs between Sri Lankan and Nigerian genotypes. The transcriptomic data sets generated here provide new resources for gene discovery and marker development in this orphan crop, and will be vital for future plant breeding efforts. We also analyzed the soybean trypsin inhibitor (STI) gene family, important plant defense genes, in the context of related legumes and found evidence for radiation of the Kunitz trypsin inhibitor (KTI) gene family within winged bean.

“…Some studies showed that seeds from E. gigas used in the preparation of traditional concoction for curing diseases in Nigeria contained essential minerals and high amount of anti-nutrient factors such as oxalate, phytate, and tannins. 4,21 These anti-nutrient factors are reduced through processing of the vegetables. Oxalate content of leaves of E. gigas is in accordance with microscopic analysis that showed abundant fragments of parenchyma with cells containing calcium oxalate crystals.…”

Introduction: Nutrition is an important aspect of public health because it is linked to many significant diseases and health problems. This work is part of the promotion of traditional foods from the Democratic Republic of Congo, particularly in the province of Bandundu, by assessing the antioxidant capacity of 4 unconventional green leafy vegetables and determining their microscopic features and their chromatographic fingerprints. Materials and Methods: Methanolic extracts from leaves of traditional vegetables were characterized for their chemical fingerprint by TLC, HPLC-DAD and their in vitro antioxidant activities using ABTS, DPPH assays. Results: The microscopic analysis of the powder of leaves showed that each species presents characteristic elements allowing their distinction. Phytochemical screening revealed the presence of flavonoids, terpenes, steroids and quinones in all species. However, Entada gigas and Psophocarpus scandens also contain alkaloids, Salacia pynaertii and Tetrochirdium congolenses also contain anthocyanins. All extracts displayed a good radical-scavenging activity at the concentration range 1 -60 µg/mL in the following order: S. pynaertii > T. congolense > E. gigas > P. scandens. S. pynaretii and T. congolense extracts showed significant antioxidant activity compared to quercetin, and this activity may depend on a synergic effect of several polyphenolic compounds. Conclusion: The high nutritive value of these traditional vegetables associated with their important antioxidant activities could contribute to diversifying diets for increased antioxidant consumption for Bandundu's population, and could provide benefits for protection against oxidative damage under different conditions including konzo.

“…En effet, leur teneur en protéine est de 25,17±0,28 pour 100 g de matière sèche. Cette teneur est inférieure à celle de Psophocarpus scandens (36 g protéines) (Harder et al, 1990), mais supérieure à celle de Gnetum africanum (16,5 g de protéines) observée par Mialoundama (1996) et 5,95 g pour la même plante par Mbemba et al (1992). Elle est aussi élevée par rapport à celles de Pteridium centrali-africanum (0,3 g), de Dioscorea praehensilis (8,5 g), de Talinum triangulare (2 g) observées par Biloso (2008), bien que les trois légumes soient riches en eau.…”

“…Les quantités de glucides 7,78 ± 0,46 g/100 g de matière sèche dans les feuilles de T. gilletii sont inférieures à celles des feuilles de Gnetum africanum 15,53 g/100 g de MS, mais supérieures à celles de Psophocarpus scandens (Kikalakasa) 5,8 g observées par Harder et al (1990), puis 2,21 g toujours pour le P. scandens et 0,87g pour le Pteridium aquilinum (Misili) tel que observés par Mbemba et al (1989), Mbemba et Remacle (1992). Cette plante parait intéressante en formulation alimentaire dans le cadre de la prise en charge et le suivi des régimes antidiabétiques ou de gestion de la glycémie.…”

Description du sujet: Les espèces de la famille de Menispermaceae n’ont qu’un intérêt restreint au Kongo central en République Démocratique du Congo. La valorisation de Triclisia gilletii (De Wild.) Staner, synonyme de Triclisia dictyophylla Diels, l’une des espèces sauvages de cette famille, apparait comme une stratégie alternative pour accroitre durablement les revenus et améliorer la sécurité alimentaire des ménages pauvres en milieu rural. C’est dans ce contexte que la présente étude a été menée.Objectifs: L’objectif de cette étude est de valoriser Triclisia gilletii (De Wild.) Staner utilisé en alimentation comme condiment dans la préparation des feuilles de manioc au Kongo central.Méthodes: L’analyse des échantillons et la détermination de la valeur nutritionnelle à travers le dosage des teneurs en glucides, protéines et éléments minéraux des feuilles de cette espèce ont été effectuées à l’aide d’un spectromètre ED-XRF Xepos III, la presse hydraulique (Specac de 1000 kg), la balance de précision (Metter Tolebo) et la tamiseuse Retsch(tamis de 63 µm).Résultats: Il ressort de cette étude que les échantillons analysés contiennent 3,7 % de l’eau, 6,53 % de cendres, 25,17 % de protéines, 3,61 % de lipides, 53,19 % de fibres, 7,78 % de glucides sans fibres, 0,12 % de Na, 0,10 % de Mg, 0,07 % de P, 0,01 % de Cl, 0,32 % de K, 1,17 % de Ca, 0,003 % de Mn, 0,16 % de Fe, 5,5 mg/kg de Cu, 12,5 mg/kg de Zn, 0,0007 mg/kg de Se.Conclusion: Les résultats obtenus ont montré que Triclisia gilletii peut être utilisé en alimentation. Cependant, des investigations supplémentaires sont nécessaires pour vérifier les propriétés médicinales de cette espèce et les techniques de transformation et conditionnement de ses feuilles. English title: Contribution to the physico-chemical analysis and bio-chemical of the Triclisia gilletii (De Wild.) Staner used in diet at Kongo Central in DRC Description of the subject: Species of the Menispermaceae family are of limited interest in central Kongo in the Democratic Republic of Congo. The valorization of Triclisia gilletii (De Wild.) Staner, synonym of Triclisia dictyophylla Diels, one of the wild species of this family, appears as an alternative strategy to sustainably increase the incomes and improve the food security of poor households in rural areas. It is in this context that this study was conducted. Objectives: The goal of this study or research is to develop (emprove) the Triclisia gilletii (De Wild.) Staner, used in diet as ingredient in the cooking of cassava leaves in Kongo Central. Methods: The samples analysis and the outstanding of the nutritional value through the dosage (amount) of the content in glucide, protein, and mineral elements of their leaves were done using a spectrometer ED-XRF Xepos III, the hydraulic press ( specac of 1000Kg) plus moulds , the precision scale (Metter Tolebo) and the Retsch sieve (63µm sieve). Results: From this study(research) we noticed that the samples analysed have 3.7 % of water, 6.53 % ashes, 25.17 % of protein, 3.61 % of lipids, 53.19 % of fibers, 7.78 % of carbohydrates without fiber, 0.12 % of Na, 0.10 % of Mg, 0.07 % of P, 0.01 % of Cl, 0.32 % of K, 1.17 % of Ca, 0.003 % of Mn, 0.16 % of Fe, 5.50 mg/kg of Cu, 12.5mg/kg of Zn, 0.0007 mg/kg of Se. Conclusion: The results obtained showed that Triclisia gilletii can be used in food. However, further investigations are needed to verify the medicinal properties of this species and the processing and packaging techniques of its leaves.
