The study aimed to determine the effect of seeds size (length, width, thickness and 100 seeds-weight) on their phytochemical composition (total phenolics, total flavonoids, total proteins, soluble sugars and starch) of cowpea accessions (Vigna unguiculata (L.) Walp.) grown in Burkina Faso. The genotypes and their descendants had length, width, thickness and 100 seeds weight between 80 ± 0.7 to 7.40 ± 0.46 cm;6.51 ± 0.41 to 5.76 ± 0.46 cm;5.15 ± 0.37 to 4.22 ± 0.22 cm;12.93 ± 0.09 to 20.16 ± 0.39 g respectively. Total phenol, total flavonoid and starch contents ranged from 585.37 ± 9.73 to 1704.71 ± 4.87 mg GAE per 100 g DW;41.42 ± 2.03 to 52.26 ± 0.75 mg QE per 100 g DW;6.45% ± 0.3% to 46.58% ± 0.12% respectively. The soluble sugars and total proteins contents were ranged respectively from 149.33 ± 3.80 to 432.82 ± 40.81 μg/100mg, and 20.28 ± 0.17 to 27.32 ± 0.17 (%). Seeds size characters had significant and positive correlations with starch content, and significant and negative correlations with total phenolic content. The study of the genetic parameters of phytochemical traits also revealed that they are slightly influenced by the environment. Genetic factors are believed to account for the variation in the observed seed traits, which provides a high potential of studied accessions for breeding programs.

Background: Liver diseases including chronic hepatitis, steatosis, fibrosis, cirrhosis and liver cancer are now a public health problem. In 2002, cirrhosis accounted for 27.63% of hepatobiliary diseases in Burkina Faso. In Africa and more particularly in Burkina Faso, the majority of the population (about 80%) uses medicinal plants for their primary health care. Calotropis procera (Ait.) *** (Apocynaceae) is a medicinal plant used in Burkina Faso in the treatment of liver problems. This work aims to evaluate the anti-fibrotic properties of Calotropis procera roots barks. Methods: The anti-fibrotic activity of the ethanolic extract of Calotropis procera roots barks was evaluated using diethylnitrosamine (DEN) to induce liver fibrosis in male Wistar rats. Serum biomarkers, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), Total protein, Albumin, Υ-Glutamyl transferase (GGT) were evaluated and the activities of antioxidant enzymes (Superoxide dismutase and catalase) as well as the level of malonedialdehyde (MDA) and that of nitric oxide (NO) were determined in the liver homogenate. Results: The treatment of rats suffering from hepatic fibrosis with the ethanolic extract leads to a significant restoration of the biomarkers of the hepatic function in particular, AST, ALP, GGT, Albumin. The extract also causes a reduction in oxidative stress in the liver through a significant increase in the activity rate of the antioxidant enzymes Superoxide dismutase (SOD) and catalase accompanied by a significant drop in the rate of MDA and NO suggesting the anti-oxidant effect of extract. Conclusion: The results of the study show that the ethanolic extract of the roots barks of Calotropis procera has anti-fibrotic properties.

Lawsonia inermis is a hairless plant growing in various regions of North Africa, the Indian subcontinent, and the Middle East. It possesses many medicinal attributes, including curative properties against infectious dermatoses. This study was carried out to evaluate the phytochemical profile of the crude ethanolic extract of the plant leaves and its fractions as well as their antimicrobial activities. The phytochemical profile was performed using high-performance thin-layer chromatography (HPTLC), gas chromatography-mass spectrometry (GC-MS), and high-performance liquid chromatography (HPLC). Additionally, the phenolic and flavonoid contents were determined using the Folin-Ciocalteu spectrophotometric and the aluminum trichloride methods. Antimicrobial activity was tested using disc diffusion and microdilution methods. The presence of flavonoids, tannins, sterols, and triterpenes was revealed. GC-MS detected twelve compounds main compounds consisting of saturated and unsaturated fatty acids and phenolic and terpenoid compounds among twenty-seven components. HPLC also detected high contents of phenolic acids and flavonoids. The most abundant triterpene and sterols were ursolic acid (around 43.14 g/100g DW, 13.9 g/100g dry weight (DW), and 0.68 g/100g DW) in the crude ethanolic extract of leaves (FeLi), hexane fraction (FHLi) and dichloromethane fraction (FDLi), respectively and, β-sitosterol in FeLi (56.7 mg/100g DW), FHLi (10.55 g/100g DW), FDLi (106.1 mg/100g DW) and butanol fraction (FBLi) (357.4 mg/100g DW). Among the flavonoids, rutin = 3.24 g/100g and quercetin = 0.63 g/100g in the ethanolic extract, rutin = 15.73 g/100g in the dichloromethane fraction, and rutin = 0.23 g/100g) in the aqueous fraction;and among phenolic compounds, caffeic acid (37.65 g/100g DW) and vanillic acid (22.70 g/100g DW) were the most important in the ethyl acetate fraction (FAeLi). All organic fractions exhibited interesting antibacterial and antifungal activities against the tested s
