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 …
