Given the dearth of medications now available to treat such disorders and their accompanying detrimental impacts, an urgent need exists for the global identification of brand-new antioxidants and acetylcholinesterase (AChE) inhibitors. This study evaluated the comparative impacts of the antioxidant and acetylcholinesterase activities of n-hexane, ethyl acetate, and methanol extracts of S. mombin leaves. The dried leaf samples of the plant were triturated. Following maceration of the powdered plant materials in each of the three extraction solvents (methanol, n-hexane, and ethyl acetate), the resulting solutions were separately subjected to lyophilization. The in-vitro antioxidant analysis was determined by employing the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and lipid peroxidation (LPO) assays. Acetylcholinesterase (AChE) inhibitory abilities of the various extracts were also evaluated using a standard protocol. The methanol extract showed the greatest DPPH scavenging (75.91%) and AChE inhibitory (40.17%) properties in the DPPH and AChE inhibitory assays, respectively. The DPPH and lipid peroxidation assays also demonstrated that all extracts had dose-dependent antioxidant properties. In addition, evaluations of each extract's ability to inhibit lipid peroxidation revealed that, at initial concentrations of 0.05 mg/L and 0.1 mg/L, the methanol extract displayed stronger LPO inhibitory effects (5.90%, 6.15%) than the n-hexane (4.00%, 5.4%) and ethyl acetate (3.26%, 3.99%) extracts. Nonetheless, the n-hexane extract showed a greater LPO inhibitory effect (10.00%, 10.34%) at higher dosages of 0.2 mg/L and 0.5 mg/L respectively. The results of this study have shown that methanol is the best solvent for exploiting the pharmacological benefits of S. mombin leaves thereby reasserting the numerous applications of the plant in traditional medicine. It has also paved the way for the development of novel therapeutic alternatives for a range of neurodegenerative disorders and other health concerns.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82601835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remnant cholesterol has been proposed to be a link between obesity and coronary heart disease, thus a risk factor for the development of cardiovascular disease in obese people.  We compared the level of calculated non-fasting remnant cholesterol, fasting and non-fasting lipid profile and fasting blood sugar in overweight, obese and normal weight participants in Nnewi, a town in South East Nigeria. \u0000Methods: In this cross-sectional study, a total of 90 apparently healthy obese, overweight and normal weight participants who met the inclusion criteria were randomly enrolled. They were grouped using their body mass index of 18.5 to 24.9 kg/m2 (normal weight), 25 to 29.9 kg/m2 (overweight) and ≥30 kg/m2 (obese). The parameters were analyzed using standard methods. \u0000Results: Our results shows that there was progressive increase of remnant cholesterol among the group, this increase has no statistical difference (p>0.05) in the mean calculated remnant cholesterol (mmol/l) between the obese (0.72±0.4), overweight (0.68±0.46), and normal weight (0.50±0.28) participants. The mean fasting Very Low Density Lipoprotein (VLDL) and Triglyceride (TG) (mmol/l) were significantly higher (p<0.05) in overweight compared to normal weight participants (0.76±0.31 vs. 0.47±0.22) and (1.72±0.60 vs. 1.09±0.51) and obese participants (0.82±0.23 vs. 0.47±0.22) and (1.85±0.59 vs. 1.09±0.51) when compared to normal weight participants respectively.

Furthermore we did not observed Remnant cholesterol as a sole predictor to obesity which will lead to cardiovascular diseases, with the rising prevalence of obesity in developing country as well as its associated complications and risks.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77442727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antioxidant activity was determined using 2,2-diphenyl-1-picryhydrazyl, lipid peroxidation and reducing power assays. Antioxidant vitamins (A, E and C) and enzymes (superoxide dismutase, peroxidase and catalase) were assayed using absorption spectroscopic methods. \u0000Results: There was a significant increase (p≤0.05) in the DPPH scavenging effect and inhibition of lipid peroxidation activity with increasing extract concentration. There is an increase in spectroscopic absorbance value as the concentration of the sample extract, in the reaction mixture, increases indicating its reducing power ability. The EC50 values for DPPH, lipid peroxidation and reducing power assays were 610 µg/ml, 640.51 µg/ml and 580 µg/ml respectively.
