Objective: Active chemical constituent in plants exhibits pharmacological action. Hence this research work aimed to identify and quantitate oleanolic acid. Methods: A simple, high-performance thin-layer chromatography (HPTLC) is developed and validated to identify and quantify oleanolic acid. The extracts were spotted as bands on aluminum TLC plates which were pre-coated with silica gel. Different compositions of mobile phase tried for high resolution and reproducible results. Mobile phase composition toluene: methanol: ethyl acetate (8.5:1:0.5 V/V) utilized. Plates were derivatized with 10% sulphuric acid and scanned. Oleanolic acid was detected quantitatively at 529nm. Result: In the selected mobile phase, Rf value for oleanolic acid was found to be 0.35, which indicated a good separation. The Chromatography method was validated with respect to Linearity range (ng), Intraday and Interday precision, Instrumental Precision, Quantitation Limit i.e., LOQ (ng), Detection Limit, i.e., LOD (ng), Repeatability for oleanolic acid as per ICH guidelines. Oleanolic acid calibration graph in 200-1200 ng range per band was found linear with correlation coefficient value 0.998. All the parameters obeyed...

Determine the fungicidal activity of five disinfectants on Candida auris of clinical and environmental origin. Assess the fungicidal efficiency of each disinfectant on the microorganism. Calculate the percentage of efficiency (% E) of each disinfectants on Candida strain and determine the specific death rate (k) and decimal reduction time for microorganisms. Analytic and experimental research with quantitative methods. We realized a strain’s workbench by culturing it in corresponding culture media. Analysis was a challenge essay, performed on four surfaces and at different exposure times; 1, 5, 15, and 30 minutes of contact between disinfectant and yeast. Once the disinfection process was carried out, what was expected was that after 15 minutes of contact between the yeasts and the disinfectants, a percentage of inhibition of the microorganism between 90 and 95% was presented, thus guaranteeing the duration of elimination of the infectious agent by disinfectants. Results show that after one minute of contact between Candida auris and disinfectant in a gloved hand, the yeast was removed when the clinical and...

Background & objectives: Diallyl disulphide (DADS) is an active component of garlic that has been claimed to have hypoglycemic effect and are beneficial in achieving glycemic control in diabetes mellitus (DM). The present study was conducted to assess the glucose utilization in erythrocytes in diabetic subjects after the exposure of DADS. Methods: The blood samples were collected from diabetic subjects; the plasma and erythrocytes were separated. The fasting plasma glucose levels were measured and the separated erythrocytes from diabetic blood samples were preincubated and posted incubated with DADS. The glucose utilized by erythrocytes and the percentage of glucose utilization were measured. Results: The present study results showed that diabetic erythrocytes exposed to DADS showed a significant rise of glucose utilization compared to untreated erythrocytes, which signifies the positive influence of DADS on glucose utilization in diabetic patients’ erythrocytes. Conclusion: DADS, through the formation of thiol derivatives, promotes glucose utilization by mimicking the actions of insulin in diabetic erythrocytes after post-incubation. This study can be concluded that DADS can be...

Alcoholic peripheral neuropathy is a potentially incapacitating complication of long-term excessive consumption of alcohol characterized by pain and dysesthesias, primarily in the lower extremities. The neurological effects of ethanol consumption are complex, encompassing both the central and peripheral nervous systems. It breaks into acetaldehyde which impairs and destroys the majority of neuronal functions. As a result, signals become intensified from the injured neurons and the nearby surrounding neurons, resulting in a painful condition. The study aims to evaluate the different doses of Erythropoietin, i.e., 250U/kg and 500U/kg, in alcohol-induced peripheral neuropathy. The present study involved evaluating the neuroprotective activity of Epo in alcohol-induced PN in rats by assessing behavioral, biochemical and electrophysiological, liver function tests, parameters. This study concludes that the two doses of Epo improved sciatic nerve conduction, behavioral studies and antioxidant activity in sciatic nerve homogenate. Among the two different doses of Epo, 500U/kg was most effective besides showing neuroprotective properties against alcohol-induced...

The medicinal plant Jasminum flexile is reported in traditional medicine as an antidiabetic and anti-inflammatory agent. There is no scientific report on the antibacterial and anti-inflammatory activity of extracts of Jasminum flexile. This study investigated the antibacterial and anti-inflammatory potential of the hydroethanol extract of leaves of Jasminum flexile, its column fractions and constituent compounds. The column fractions MF14, MF9 and MF5 expressed a zone of inhibition of 12 mm against Streptococcus mutans and the isolated compound JFLC1 showed a zone of inhibition of 10 mm against Streptococcus mutans, Escherichia coli, and Klebsiella pneumoniae comparable to that of the standards ampicillin, kanamycin and chloramphenicol respectively at the same concentration. The highest anti- inflammatory potential was found for the column fraction MF3 (55.14%) as assessed from the percentage of haemolysis. The results reveal that the isolated compounds and extracts of leaves of Jasminum flexile possess significant antimicrobial and anti-inflammatory...
