Antiulcer activity of MEAC was investigated by using Ethanol induced gastric mucosal damage and Pylorous ligated gastric ulcers. Evaluation was done on both models comparing with reference standard Omeprazole (20mg/kg). The parameters taken to assess anti-ulcer for pylorus ligation method were volume gastric secretion, pH, free acidity, total acidity and ulcer index. In vivo studies were carried on the plant extract and results were found that protection of the Methanolic extract of Allium cepa leaves against characteristic lesions may be due to both reduction in gastric acid secretion and gastric cycloprotein and this may be due to the presence of Flavanoids. In this study we observed that, Methanolic extract of leaves of Allium cepa (MEAC) provides significant antiulcer activity against gastric ulcers in rats. The result of MEAC showed significant reduction in the ulcer index, when compared to control. The antiulcer activity extract may be attributed to their flavanoids content and antioxidant property. These findings indicate that MEAC display potential antiulcerogenic activity.","PeriodicalId":8550,"journal":{"name":"Asian Journal of Research in Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83444549","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}

Some research groups have reported the successful use of naturally occurring substances to inhibit the corrosion of metals in acidic and alkaline environments. Among the various eco-friendly inhibitors, plant extracts are becoming more and more popular. In this study, the inhibitive and adsorption properties of the flower extract of Rumex viscarius L. as corrosion inhibitors of the carbon steel XC70 in the 1N; HCl and H2SO4 medium were investigated using the weight loss method of monitoring corrosion. The significance of the corrosion inhibition in the 1N; HCl and H2SO4 medium has been discussed. The corrosion rate was found to decrease with an increase in the concentration of both inhibitors in an acidic medium. But the corrosion rates were observed to be increased in the presence of inhibitors in an HCl medium. The maximum inhibition efficiency in H2SO4 and HCl was found to be 95.58 and 91.58% with 12.5% (v/v) concentrations of the inhibitor, respectively. The adsorption mechanism between the extract and the carbon steel substrate is found to obey Langmuir and Temkin isotherms.

The separation was performed at 210 nm by using Inertsil ODS 3V (250 * 4.6 mm, 5.0 m) column and acetonitrile/phosphate buffer (pH =3.55) as the eluent under isocratic elution conditions at a flow rate of 1.0 mL/min. \u0000Results: Escitalopram oxalate and atazanavir sulphate peaks were eluted at 2.636 and 3.319 minutes and no interference was observed in the diluent blank at the respective retention times, indicating that the developed method was specific and selective. A linear relationship was found for escitalopram oxalte (2.5 - 15 µg mL-1) and atazanavir sulphate (30 - 150.0 µg mL-1), with coefficient of regression greater than 0.999. Based on the RSD values (< 2.0%) and recovery results (> 98%), the developed method is accurate. At room temperature and in the refrigerated conditions, standard and sample solutions of escitalopram oxalate and atazanavir sulphate have been found to be stable for 48 hours. \u0000Conclusion: The established method is linear, precise, accurate, specific, and robust in the studied concentration range. Accordingly, the proposed method can be applied to the analysis of experimental tablet formulations as well as bulk drug samples.","PeriodicalId":8550,"journal":{"name":"Asian Journal of Research in Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81787779","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 principle of using tailam is better absorption of active ingredients by skin when applied through a lipophilic vehicle like vegetable oils. Marichadi Tailam is a herbal oil used for treatment of skin diseases such as eczema and dermatitis. In the present study, an attempt was made to develop and validate a HPTLC method for quantitative determination piperine in the Marichadi coconut oil and its standardization. The HTPLC separation was performed on precoated silica gel 60 F254 aluminum plate (10 × 10cm, 250μm thickness) using toluene:ethyl acetate:diethyl amine (7:2:1) as a mobile phase. The detection and quantification was performed at 340nm. The formulation contains 2.35% of piperine.

The scattered white silicon dioxide (SiO2) powder was evenly mixed with barium titanate (BaTiO3 or BT) powder in the same epoxy resin (RE) matrix. Over a frequency range from DC to 30 GHz, the dielectric behavior of these composite samples is examined, adding in particular a low frequency study at 500 MHz. The BT addition grew the mixture dielectric permittivity from 3.6063 to 8.2313 and moving the resonance frequency (ƒr) in the direction of the low frequency from 26.245 GHz until 17.09 GHz. By improving the shape factor smoothing and bringing theoretical and experimental results closer together, this seeks to optimize the modified Lichtenecker's law (MLL). These findings comparison demonstrates that the MLL model applies to ternary composites (RE-BT-SiO2) with an acceptable accuracy level. Another numerical method was used to evaluate the RE-[RE-BT-SiO2] composites employing a binary mixing model based on an MLL equation that is identical to the former ternary. This model results correlate well with binary composites experimental values as well as ternaries that are modeled using this law.
