“…In addition, an absence of flavonoids, sterols and terpenes in the aqueous extract of Bauhinia thonningii leaves was observed by Ouattara and al. (2020) [22]. This difference could be explained by the variability in the composition of the organs of the same plant due to biotic and abiotic factors and the extraction solvents used.…”

The aim of this study was to identify the groups of chemical compounds present in the aqueous extract of B. thoninginii bark from Ivorian flora and to assess its antibacterial activity against multi-resistant strains of P. aeruginosa and A. baumannii. Phytochemical sorting was used to identify polyphenols, flavonoids, tannins, coumarins, alkaloids, terpenes and derivatives. The levels of polyphenols, flavonoids, flavone aglycones, anthocyanins and condensed tannins were respectively 0.748 ± 0.03, 0.091 ± 0.01, 0.0094 ± 0.03, 0.0359 ± 0.01 and 0.117 ± 0.02 mg EAG /g MS. Sensitivity tests showed that BT was ineffective against multi-resistant strains of P. aeruginosa and A. baumannii.

Plants have been used traditionally by people in treating and the management of diseases since time immemorial. Traditional medicines including the herbal medicines are used for primary healthcare in some domains in almost every country. Approximately 80% of the population in developing coutries depend on plants as their source of medicine for combating diseases. New and effective antimicrobial agents that have novel mechanism of actions are required. Piliostigma thonningii (Schumach.) Milne-Redh. is a species of flowering plants in the legume family, Fabaceae. Different parts of the P. thonningii plants such as the roots, leaves, seeds, and fruits have been used in treating wounds, heart pain, and gingivitis and as cough remedy. This study focused on determining the antimicrobial properties found in the pods of P. thonningii. The sample was prepared by grinding the dried pods into a fine powder. Successive extraction and extraction with 1 : 1 DCM: methanol was used. The antimicrobial assay was carried out using the broth microdilution and MTT assay. The microorganism used for the tests was Pseudomonas aeruginosa, Candida krusei and Mycobacterium smegmatis. The most potent extract was then used to determine its effect on microbial cell membrane integrity. The results showed that methanol extract had the highest percentage yield of 5%. The extract with the highest antimicrobial effects was ethanol extract with the 100 μg/mL concentration inhibiting the growth of cells to 26%, 87%, and 90% for P. aeruginosa, M. smegmatis, and C. krusei, respectively. The ethanol extracts caused significant leakage of proteins in these microorganisms. In conclusion, the pods of P. thonningii contain phytochemicals with antimicrobial properties. The pods of the plant can be a source of phytochemicals that can serve as sources of lead compounds with antimicrobial effects. One of the mechanisms of action of these phytochemicals is via membrane-damaging effects on microbes.

Tomato production in Cameroon faces numerous constraints, including post-harvest rot. This study was carried out with the aim of contributing to the fight against post-harvest rot of tomato fruits through the use of the aqueous extract of Ageratum conyzoides. To achieve this objective, the pathogen responsible for tomato fruit rot was isolated and the microscopic and macroscopic characters determined; the antifungal activity of the aqueous extract of A. conyzoides was evaluated in vitro using three doses (30, 60, and 120 mg/ml) with three repetitions at three different periods (before, during and after) fruit treatment by the extract and inoculation of the pathogen on scarified and non-scarified fruits. A synthetic fungicide Pencozeb served as a positive control. Parameters such as mass loss of tomato fruits, surface area of lesions induced on scarified and non-scarified tomato fruits, were measured using a balance and graph paper respectively. The results show that Fusarium oxysporum was the pathogen responsible for rotting tomato fruits and having the macroscopic characteristic of a cottony texture and a white aerial mycelium, macroscopically, Fusarium oxysporum presents two types of asexual spores, namely macroconidia which are curved, pale-colored spores, and microconidia which are ovoid spores with septate and branched hyphae, a smooth and thin cell wall. The antifungal test revealed that the aqueous extract showed an effect inhibitor on the development of the lesion surface and mass loss at the highest dose 120 mg/ml when the extract applied twenty-four hours (24 hours) before inoculation on the fruits was fungicides at a concentration of 120 mg/ml on Fusarium oxysporum. The pathogen-induced lesion area and mass loss of scarified tomato fruits were 6.000±3.09 and 10.04±9.37 respectively. In non-scarified fruits these values were 8.45±3.43 and 48,000±13.66 respectively for lesion area and mass loss. This extract can therefore be used as an alternative to chemical pesticides in fruit preservation
