Naturally inherited herbs are almost lost and only very few are left in the herbal trade. The study therefore assessed the medicinal values of Rauvolfia vomitoria and its availability in Ibadan municipality with the use of structured questionnaires and target informant interview. A multistage sampling procedure was used to collect data on medicinal values of Rauvolfia vomitoria. Data collected were analyzed using descriptive and cross tabulation. The findings revealed that Rauvolfia vomitoria has a lot of medical potential in curing and preventing ailments like malaria, typhoid, and jaundice among others. It also has aesthetic effects on human beings and their environment. The plant is abundant at both seasons of the year as testified by 95% of the respondents. It is therefore recommended that sustainable management and domestication of Rauvolfia vomitoria must be ensured for posterity. In the same vein, preservation techniques of the harvested parts must be intensified to avoid quick spoilage.
Chrysophyllum albidum (African star apple) fruit is among the well known indigenous fruit trees in the tropical rainforest zone of the Western region of Africa. The fruits are much cherished by both the young and the old and are of huge commercial interest in Nigeria. The fruits often deteriorate within a very short period and become spoilt as a result of fungi attacks. The study therefore carried out the survey of fungi attacks on C. albidum and investigates the etiology of post harvest deterioration. Fresh fruits were procured from purposively selected markets in Ogun State for microbial analysis. Descriptive and cross tabulation analysis were used to analyze the data and these include: percentages, frequency distribution and cross tabulation. The results of this study showed that five fungal genera were associated with African star apple fruits. The fungi found on the surface of the fruits were Fusarium solani, Aspergillus niger, Aspergillus fumigatus, Penicillium citrinum, Lasiodiplodia theobromae and Rhizopus spp. Fusarium solani was the most abundant and prevalent in almost all the localities. The incidence of the occurrence of fungi found associated with highest percentage of Lasiodiplodia theobromae (40.37%) and Fusarium solani (26.23%) respectively. The least occurrence of all the fungal isolates is Aspergillus flavus. Aspergillus niger, Penicillum citrinum and Aspergillus fumigatus. They all were found to be pathogenic to C.albidum fruits and responsible for their spoilage. Therefore the use of local preservatives (plant extracts) like Afromomum danielli, Afromomum melegueta and chemical disinfectants like paraozone, sodium chloride and sodium benzoate at mild dosages were recommended to reduce the losses due to storage moulds. Early harvesting of the fruits, prevention of over ripening and keeping the fruits dry and cool at all time should be ensured.Keywords: Chrysophyllum albidum, fungi attacks, etiology, microbial analysis, preservatives
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.
