This study investigated the effect of motivation on memory recall among students of SS11A and SS11B of Government Model Secondary School Makurdi. The study employed the use of experimental design of 3x2x1 One-Way Analysis of Variance (ANOVA) and Independent T test with Alpha level of .05 to test the two hypotheses. The study consists of sixty (60) participants with 30 (50%) males and 30 (50%) females. Their ages ranged from 13-20 years with the means of 8.15 (SD=23.41). The participants were grouped into three of high, low and non-motivated students. Each group had (20) participants each totalling sixty (60) in the study. The participants were selected on the basis of gender and evenly distributed through the use of purposive and convenience sampling techniques. Finding from the study indicated that there was significant different in the level of memory recall among the high, low and non-motivated students F (2, 57) =8.98, P<.05. There was no significant different between male and female students on memory recall when motivated (59) =.20 P>.05. Thus, the first hypothesis was confirmed and the null hypothesis was rejected. On the other hand the second hypothesis was rejected and the null hypothesis was accepted. It was therefore recommended that conscious efforts should be made by the parents, Teachers, School Administrators to provide various incentives to enhance students recall abilities in memory task. It was also recommended that the Government and Philanthropists should provide scholarship programme to enhance study memory recall in the Secondary School. Finally, the study recommended that psychologists and the teachers should encourage the student to always rehearse their work in order to improve their memory recall when the need arise.

This research investigated the suitability of various solvents used in the fractionation of methanol leaf extract of P. americana to ascertain the flavonoid, vitamin and amino acid profile of the fractions. It has been demonstrated that a number of Persea americana plant components contain different phytochemicals associated with important biological function. Fresh leaves of P. americana were harvested from Baissa in Taraba State. The plant materials were air dried under shade at ambient temperature. The dried plant materials were pulverized to fine powder using mortar and pestle. The pulverized plant material was soaked in methanol for 72 hours for extraction. The extract was filtered using clean filter cloth and filter paper under reduced pressure. The filtrate was evaporated in in rotary evaporator and water bath to obtain the required concentrate. The extract was used to perform fractionation using separation funnel and solvents of different polarity such n-hexane, methanol and ethanol. Each of the fractions was used to analyze for flavonoid, vitamin and amino acid profile using HPLC. The result reveals that quercetin is present in each of the fractions. Caffeic acid phenyl ether was detected in diluted ethanol fraction, coumaric acid was identified in diluted n-hexane fraction, caffeic acid was identified in methanol fraction chlorogenic acid detected in n-hexane fraction. Vitamin K was identified in all the fractions, Vitamin B1 was identified in diluted ethanol fraction and n-hexane fraction while vitamin B9 was detected in diluted n-hexane fraction and n-hexane fraction. Vitamins B2 and B6 were identified in methanol fraction and diluted ethanol fraction respectively. The diluted ethanol fraction was seen to contain 8 different amino acids followed by the methanol fraction with 6, then the diluted n-hexane fraction with 3 and the n-hexane fraction with 2. This reveals that for isolation of amino acids, the ethanol fraction may be more suitable considering that the highest number of amino acids were found in it.

HPLC techniques were employed to analyze the bioactive components of the chloroform leaf extract of Kalanchoe pinnata leaf from Takum in Taraba State. A botanist from Taraba State University's Department of Biological Sciences in Jalingo identified the plant leaves, which were then gathered, cleaned, and processed. Using cold maceration, extraction was done by weighing 1500g of the powdered leaf into 1 liter of ethanol and distill water, respectively. Until further investigation, the extracts were stored in a refrigerator in a firmly closed container. The injection valve was used for the HPLC analysis, and the conditions were 20 μl, a UV variable wavelength detector (set at 300 nm), reprosol 100 C8mn, 5 μm 4.6 x 150mm column (30°C), and sensitivity of 0.001. Phosphate buffer (v/v) was used as an aqueous solvent (A) and CH3CN as an organic solvent (B) in HPLC. Gradient elution of the analytes occurred at a flow rate of 1 milliliter per minute. Software generated chromatograms. Operating temperature of the HPLC instrument was room temperature (23 ± 2°C). After injecting 20 μl of each diluted extract into the HPLC three times, the average peak areas were produced and utilized for quantification. Based on the HPLC analysis, the chloroform leaf extract of Kalanchoe pinnata contained the following bioactive constituents: quercetin, gallic acid, and chlorogenic acid. Additionally, the presence of vitamins B1 and B3 was also noted. The different bioactive constituents eluted at different retention times, and their respective amounts were also detected.

The recent study investigated the effects of ethanol extract of Brassica oleracaeae leaves on prednisolone induced toxicity in male albino rats. Liver markers were assayed in order to investigate the toxic effect of prednisolone and the ameliorating effects of the extract. Sixteen (16) rats grouped in to four (n=4) were administered prednisolone and ethanol leaves extract based on the experimental design. The male albino rats were sacrificed after the experimental period of fourteen (14) days, blood was collected for assay of the liver function by ocular puncture. Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) levels were significantly (p<0.05) increased from 5.67 ± 5.13 and 6.67 ±7.02 to 26.67 ± 8.02 and 25.00 ± 4.00 respectively when rats where administered with prednisolone toxicity. Upon treatment of rats with ethanol leaves extract of B. oleraceae at 100mg/kg, the concentration of AST and ALT were lowered to 7.67 ± 6.81 and 8.00 ± 7.55 respectively. A further increased in the concentration of the extract to 300mg/kg resulted to a significant (p<0.05) increased of AST (9.33 ± 8.12) and ALT (12.00 ± 10.00) levels. Similarly, the levels of alkaline phosphatase (ALP) and Albumin increases in the group that were administered with prednisolone however, when rats were treated with ethanol leaves extract of Brassica oleracaeae such concentrations were decreased. The findings of this study can be concluded that, the ethanol leaves extract of Brassica oleracaeae showed capacity in ameliorating the effects induced by prednisolone intoxication.
