“…Furthermore, the present research is in agreement with previous finding as given below. Nasiru et al [14] reported the insecticidal activity of Tamarindus indica, Azadirachta indica and Jatropha curcas leaves powder against maize weevil (Sitophilus zeamais). The results show that T. indica was found to be the most effective in the seeds treatment with 97%, while A. indica and J. curcas have 66% and 40% adult mortality at 1.0, 1.5 and 2.0g/20 maize seeds respectively.…”

This research reports the novel bioactivities of neem leaves powder, neem leaves concentrate, neem seeds powder and neem seeds oil against the weevil (Callosobruchus maculatus) on bambara groundnut. The leaves were ground, crushed and subjected to ethanol to get the concentrate. While the seeds were dried under shade for one week, ground into fine particles. Cold bulk extraction was then used to obtain the neem seeds oil. The mortality count of Callosobruchus maculatus (C. maculatus) was studied by exposing the weevil to neem treated bambara groundnut at different days under laboratory condition. The neem dosage were 0.0, 0.1, 0.5 1.0 g/10 g of bambara groundnut. The percentage weight loss and seed damage were also determined at the end. The results indicated that neem seeds oil and neem leaves concentrate provided effective and comparable mortality counts against the C. maculatus. Again the neem powder (seeds and leaves) mortality counts were also comparable, but were less effective against the weevils as compared to the neem oil and concentrate at least for the first two days. Therefore, these neem materials could be used as biopesticides at the dose of 0.1 per 10 g to prevent C. maculatus attack on bambara groundnut during storage. This will reduce the usage of synthetic pesticides, thereby preventing their adverse residual effects on human and the environment.

“…Cerulenin is an inhibitor of fatty acid and transcinnamic acid, which was recently shown to augment the activity of various antibiotic drugs against M. avium [24]. Cerulenin is a known inhibitor of fatty acid synthetase [25,26] and has been reported to inhibit the biosynthesis of both unsaturated and saturated fatty acids as well as that of total phospholipids in M. smegmatis. Trans-cinnamic acid is a bacteriostatic even at concentrations as high as 200 μg/ml, whereas cerulenin was bacteriostatic until 50 μg/ml.…”

“…It is clear that the major basis of the electrochemical methods is the analysis of the relationships between detection and current, voltages and resistance. Evolution of novel substances may lead to the building of novel electro-chemical sensors with higher sensitiveness and steadiness [7,8] that have benefits, such as rapid responses, excellent mobility, simple operations, affordability, greater precision, and lower limits of determinations in comparison to the HPLCbased procedures [9][10][11].…”

The present study designed an electro-chemical instrument with high sensitivity and selectivity on the basis of a SPE modified with La +3 /Co3O4 nano-cubes in order to analyze vitamin B9. It was confirmed that this sensor possesses very good electronmoderating behaviors to oxidize vitamin B9 in a 0.1 M phosphate buffer solution (PBS) (pH=7.0). In addition, according to optimal conditions (pH=7.0), a potential around 110 mV less positive than the one in the un-modified electrodes is required for vitamin B9 oxidation at this electrode surface. This technique limit of determination for vitamin B9 has been estimated to be 0.3 μM (S/N = 3). Responses have been linear in concentrations range between 1.0 and 600.0 μM. The modified electrode has been applied to detect vitamin B9 in real specimens, which was accompanied by acceptable outputs. Experiments showed that La +3 /Co3O4 nano-cubes will be valuable electrode materials providing a high ratio of surface to volume that enhances sensitivity. The study introduces a novel sensor with simpleness, quickness, sensitivity, and affordability features to quantify vitamin B9. A nano-sensor based on screen printed electrode (SPE) for electro-chemical detection of vitamin B 9 .
