Quantitative Determination of Isomeric Components of essential oils by RP-HPLC-PDA in multi-herbal tablets
Abstract: Essential oils are lipophilic and highly volatile secondary plant metabolites, principally mono- and sesquiterpenes. The widespread usage and applications in biopharmaceutics and cosmoceutics of these components drives their quality assessments criteria to be established. Gas chromatography is one of the predominantly used technique for analyzing volatile oils. Although Gas Chromatography employs estimation designs operated at elevated temperatures leading for plausible structural alterations of thermo labile compounds. Hence, a novel gradient …

Amentoflavone and Mangiferin in Hypericum calycinum, Hypericum cardiophyllum and Hypericum bithynicum
Abstract: The present study was conducted out to determine amentoflavone and mangiferin contents of Hypericum calycinum, Hypericum cardiophyllum and Hypericum bithynicum, growing wild in Turkey. The aerial parts representing a total of 30 individuals were collected at full flowering, dried at room temperature and assayed for secondary metabolite concentrations by HPLC-PDA. Both compounds were detected in all three species in different amounts depending on plant tissue. Results were discussed in phytochemical …

Determination of Pesticide Residues in Agricultural Soil using High Performance Liquid Chromatography (HPLC), Gazipur District, Bangladesh
Abstract: This study was undertaken to determine the presence of pesticide residues in some agricultural soils of Gazipur district in Bangladesh. The collected soil samples were analyzed for some selected pesticides such as DDT, methoxychlor, acephate, fenthion, fenitrothion, parathion, ethion, carbaryl, carbofuran and cypermethrin by using high performance liquid chromatography (HPLC) with PDA detector. The results showed that none of the soil samples were contaminated with organochlorine and pyrithrium pesticides. Soil …
