The colored reaction products in both cases were measured at the maximum absorptions of 540 nm and 440 nm, respectively. The absorbance measured in each assay as a function of TBH concentration was related to TBH concentrations. Different experimental and variable conditions of assays were done carefully, accurately studied, and optimized. The validation of two assays also was done by following the current guidelines of the International Conference on Harmonization (ICH). Beer’s law for the two methods is obeyed over the concentration ranges 1-15 µg/ml (Correlation coefficient = 0.9983) and 1-18 µg/ml (Correlation coefficient = 0.9989) for methods PP and DSOQ, respectively. Molar absorptivity, limits of detection, and quantification (LOD & LOQ) values were (1.38×104 l/ mol cm, 0.92 & 2.78 µg/ml) for PP assay, and (1.73×104 l/ mol cm, 0.09 & 0.27 µg/ml) for DSOQ assay, respectively. The two assays were successfully applied for the determination of TBH in commercial tablets with reliable and satisfactory results, and hence the proposed assays can be applied in pharmaceutical laboratories of quality control.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":"48 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141650076","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 analysis focused on identifying various functional groups such as -OH vibrations associated with polysaccharides, C-H vibrations from lipids and lignin compounds, and C=O vibrations related to cellulose derivatives. The total phenolic, flavonoid, flavanol, tannin, and proanthocyanidin contents of S. orientalis seeds, stems, and flowers were evaluated using standard analytical methods. DPPH radical scavenging activity was determined to assess antioxidant potential, with IC50 values calculated for each plant part. Quantitative analysis of phenolic compounds in the plant extract was conducted using LC-MS/MS. The abundance of various phenolic acids including P-coumaric acid, trans-ferulic acid, caffeic acid, and vanillic acid was determined. Additionally, other phenolic compounds such as gallic acid, chlorogenic acid, salicylic acid, (+) taxifolin, rutin hydrate, ellagic acid, quercetin dihydrate, and apigenin were also detected and quantified.\u0000Result and Discussion: The evaluation of phenolic content showed differences among different plant parts, with flowers exhibiting the highest total phenolic and proanthocyanidin content. Seeds demonstrated superior DPPH radical scavenging activity. Quantitative analysis of phenolic compounds using LC-MS/MS highlighted the abundance of various phenolic acids and other phenolic compounds in S. orientalis. These findings underscore the potential of S. orientalis as a valuable source of natural antioxidants. Overall, the results suggest that S. orientalis possesses significant phenolic diversity and antioxidant activity, which could contribute to its potential applications in various industries, including pharmaceuticals and nutraceuticals.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":" 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668748","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}

This study delves into the impact of superdisintegrants (crospovidone, sodium starch glycolate, and croscarmellose sodium) on the in vitro characterization of Ketoprofen-containing ODTs. ODTs are designed to rapidly disintegrate in the oral cavity without water, enhancing patient compliance, ensuring faster therapeutic onset, and providing convenience.\u0000Material and Method: The micromeritic properties of pre-compression Ketoprofen ODT blends were assessed for bulk density, tapped density, Hausner ratio, and compressibility index. ODTs were formulated using a direct compression method to maintain component uniformity. Comprehensive characterization included weight variation, tablet hardness, friability, wetting time, and in vitro disintegration time assessments. The drug content was determined through UV spectrophotometry of dissolved ODTs, and dissolution studies were conducted in pH 6.8 phosphate buffer using USP apparatus XXIV.\u0000Result and Discussion: Results showed uniform tablet mass and favorable powder mixture flowability, ensuring ODT physical properties. Tablets exhibited excellent mechanical resistance with consistent hardness and low friability loss. All formulations demonstrated high and uniform drug content. Different superdisintegrants influenced wetting, disintegration, and dissolution times. Crospovidone exhibited the fastest wetting time but longer disintegration times, attributed to increased tablet hardness. Dissolution studies revealed that crospovidone-containing ODTs had faster drug release compared to croscarmellose sodium and sodium starch glycolate, aligning with literature findings. The study emphasized the importance of considering both wetting and disintegration times for a comprehensive evaluation of ODT performance. Croscarmellose sodium and sodium starch glycolate hindered drug release, forming gel-like masses impeding dissolution, while crospovidone enhanced drug release in formulated ODTs.
