In Chinese medicine, Zingiberaceae are acknowledged for their anti-inflammatory and antioxidant properties, which contribute to immune system reinforcement. They are known to promote digestion, alleviate nausea, motion sickness and are involved incombating flu and cold. The current study was conducted to investigate the antioxidant and anti-inflammatory properties of the methanolic extract of Siphonochilus aethiopicus (MESA). \u0000Methodology: The in vivo study examined the anti-inflammatory impact of the extract (75, 150, and 300 mg/kg) using a formaldehyde-induced inflammation mouse model. The anti-arthritic effect of the MESA was determined by measuring paw diameter, body weight, biochemical parameters (C-reactive protein and rheumatoid factor) including oxidative stress markers (malondialdehyde, superoxide dismutase, catalase, and nitric oxide), and hematological parameters. Additionally, a histopathological examination was conducted to evaluate the outcome of treatment on tissue integrity. \u0000Results: Results obtained show that the MESA significantly decreased paw inflammation (P < 0.05 to P < 0.001) and enhanced hematological and biochemical parameters. Additionally, MESA significantly ameliorated oxidative stress parameters (P < 0.05 to P < 0.001). \u0000Conclusion: This finding suggests that Siphonochilus aethiopicus possesses strong antioxidant and anti-arthritic activity, supporting its traditional application as a remedy for rheumatoid arthritis.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141111195","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}

In this study, we investigated the fatty acid compositions of various pet foods, including chicken powder, poultry byproducts incorporated vegetables, byproducts incorporated with ragi, and boiled mash Potato, to assess their scientific significance and potential implications for pet nutrition. Our analysis revealed diverse fatty acid profiles across the different pet foods, with each food exhibiting unique compositions and proportions of fatty acids. Notable findings include the identification of common fatty acids shared among multiple pet foods, as well as variations in the abundance of specific fatty acids across different formulations. Additionally, certain pet foods are characterized by the presence of rare or unusual fatty acids, highlighting the importance of exploring their sources and potential health benefits. By correlating the fatty acid compositions of pet foods with metabolic pathways and health implications, we elucidated the nutritional significance of these dietary components for pets. Furthermore, we identified areas for further research, including the impact of processing methods on fatty acid profiles and the development of novel formulations optimized for pet nutrition and well-being. Overall, this study contributes valuable insights into the scientific understanding of pet nutrition and underscores the importance of considering fatty acid compositions in formulating balanced and nutritious diets for companion animals.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141013166","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}

It is used empirically against certain pathologies such as malaria, diabetes, hemorrhages and typhoid fever. However, there is no scientific data on its phytochemical and biological profile, so this study was carried out to research the chemical groups contained in the leaves of this plant and determine the toxicological parameters which would justify its use in traditional medicine. Several standard characterization methods were used for phytochemical screening of aqueous and   hydroethanolic extracts of Pavetta corymbosa leaves. The study of the acute toxicity of the two types of extracts from the leaves of this plant was carried out according to the OECD guideline 423 using Wistar rats. Phytochemical screening indicated the existence of polyphenols, saponosides, quinones, flavonoids, polyterpenes and sterols in the two types of extracts of this plant, which would justify its biological and pharmacological effects. The study of the acute toxicity of these two types of extracts, administered intraperitoneally to Wistar rats, showed no mortality of the rats. These toxicological results allow us to qualify the leaves of Pavetta corymbosa as being non-toxic, hence the interest in its use in traditional medicine against certain pathologies.","PeriodicalId":8535,"journal":{"name":"Asian Journal of Research in Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140671619","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}

A systematization of meso combinations includes the following types: (A) meso Homodimers possessing one super-symmetric isomer or two real or envisaged C2 symmetrical enantiomers; (B) meso Heterodimers with a binding support having geometric or optical symmetry (e.g. >CR2, etc.). (C) meso Heterodimers with a binding support devoid of symmetry (of the form >CRR’, etc.), seeable as meso, and provable in this way not by themselves but by their equivalent meso homodimers.

The study aimed to determine the in-vitro bioequivalence of amoxicillin capsules from various brands using physicochemical and spectroscopic parameters. Weight uniformity, friability, disintegration, dissolving tests, and UV spectroscopy were used to determine the in-vitro bioequivalence of different brands of amoxicillin capsules. The weight variation for all the capsules showed compliance with the USP specifications (≤10% weight deviation). All brands complied with the USP/BP specification for the disintegration test, as disintegration time ranged from 7 to 12 minutes. The dissolution profile of the innovator and the generic brands showed a percentage release from 80.81 – 89.11% within 30 minutes. The first-order kinetics, t1/2 and k of amoxicillin released ranged from 16.01 – 27.11 min and 2.56 – 4.33 x 10-2 min-1 respectively. A straight-line graph was obtained as a calibration curve of amoxicillin. UV absorption spectrum showed four distinctive peaks at 240, 275, 320, and 360 nm, with the maximum at 240 nm, while the percentage content of amoxicillin ranged from 90.58 ± 1.38 to 98.74 ± 0.97%.  This result complied with the BP and USP specifications.

The filtrate was concentrated in a rotary evaporator under reduced pressure to obtain powdery form termed LLFPME. The LLFPME was tested for the presence of phytochemicals using TLC and GC-MS technique. The phenolic and flavonoid contents of the extract were quantified; the antioxidant potential of the extract was examined using DPPH and H2O2 radical scavenging, metal chelating, FRAP and TAC assays. The anti-inflammatory potential was evaluated using the membrane stabilizing and lipoxygenase inhibitory activities while the antibacterial activity was investigated by determining the zone of inhibition, minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of extract against the test bacterial isolates. \u0000Results: TLC revealed the presence of flavonoids, saponins, alkaloids, tannins, and others while the GC-MS analysis also showed the presence of 27 compounds. It was shown that the LLFPME displayed measurable antioxidant activity by exhibiting DPPH and H2O2 free radical scavenging potential and dose dependent metal chelating ability. FRAP and TAC were estimated to be 14.88 ± 0.04 and 25.53 ± 0.21 mgAAE/g of extract, respectively. The extract protected the RBC membrane integrity of RBC subjected to heat and hypotonic stress; and inhibited the activity of lipoxygenase.
