In Africa, many of the plant resources of high nutritional value are not yet included in the uses of local populations. This study contributes to the enhancement of the lipid potential of Musanga cecropioides (R. Brown) seeds. Soxhlet seed oil extraction gave a yield of 8.62%. The evaluation of the physical parameters of the oil brings it closer to that of Argan oil. The oil extracted from the seeds of M. cecropioides consists mainly of three major fatty acids: oleic acid (48.58 ± 0.63%), linoleic acid (26.74 ± 0.53%) and palmitic acid (15.05 ± 0.21%), the determination of which is made by CPG-MS. This fatty acid composition places M. cecropioides oil among oleic/linoleic oils with potentially nutritional properties. The search for minor compounds in the oily fraction shows carotenes, tocopherols and sterols on thin layer (TLC). The antioxidant activity of M. cecropioides oil is evaluated by the anti-free radical test on TLC and spectrophotometer using DPPH. The results obtained from the antioxidant activity of Musanga cecropioides oil show an important radical scavenging activity with the value of IC50 (1.539 ± 0.013 mg/mL) and a strong activity of the unsaponifiable fraction and the latter is due by the unsaponifiable fraction with an IC50 (0.073 ± 0.004 mg/ml). Analysis of the sensory and physical profile of the oil extracted from the seeds of Musanga cecropioides shows that it could be used in cosmetics, pharmaceuticals and food.
The difficulty of water supply is a major problem faced by the households of Brazzaville in Congo. The objective of this study is to list and identify the different types of water used, and to assess the general hygiene of households. The method used in this prospective study is based on an onsite survey and direct measurement. The survey involves administering a questionnaire to the households in the 9 districts of the city of Brazzaville. 630 households were surveyed. 70 households were drawn in this study and were selected in each borough. There are many sources of water. Overall, 80.16% of households consume water from the SNDE. The survey revealed that 71.00% of households walk on foot to get access to water supply. Plastic cans and buckets are used more in the transportation (43.00 and 37.00 %) and storage (45.00 and 39.00 %) of water. The water storage period is relatively long. It can hold water from 3 days (21.00%) to more than one week (13.00 %) for some households. Analysis of the results of the survey showed that the sources of water supply are diversified. This diversification is due to the phenomenon of shortage and/or repeated water cut recorded by households. Water supply, transport and storage practices, and the cleaning of water containers highlight the precarious conditions of hygiene and sanitation households in the city of Brazzaville
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
