Abstract

Medicinal and aromatic plants are alternative products to synthetics because of their antioxidant, antimicrobial, anti-inflammatory and antidiabetic effects. The objective of this study is to investigate the automated solvent extraction (ASE) process parameters for the extraction of bioactive-rich substances from purple basil (Ocimum basilicum L.). Process optimization in relation to total phenolic content (TPC), total flavonoid content (TFC), and total anthocyanin content (TAC) was performed through a chemometric approach. The ASE system was designed, modelled and optimized by 3-factor and 3-level Box-Behnken design of Response Surface method (RSM). Antioxidant activity of the samples were measured by 2 different free radical scavenging activity assays (ABTS and DPPH). By using principal component analysis (PCA) to the dataset, the impact of interactions between the parameters was also evaluated according to their antioxidant activity, TPC, TFC and TAC levels. The optimal ASE conditions (0.3 g of purple basil, 19 min of immersion time and 66 % ethanol solution) provided the highest yields of TPC (98.888 mg-GAE/g-DM), TFC (27.033 mg-CE/g-DM) and TAC (11.556 mg-C3G/g-DM), which were verified by satisfactory validation findings (the error<2 %).

期刊介绍： This journal is an international medium directed towards the needs of academic, clinical, government and industrial analysis by publishing original research reports and critical reviews on pharmaceutical and biomedical analysis. It covers the interdisciplinary aspects of analysis in the pharmaceutical, biomedical and clinical sciences, including developments in analytical methodology, instrumentation, computation and interpretation. Submissions on novel applications focusing on drug purity and stability studies, pharmacokinetics, therapeutic monitoring, metabolic profiling; drug-related aspects of analytical biochemistry and forensic toxicology; quality assurance in the pharmaceutical industry are also welcome. Studies from areas of well established and poorly selective methods, such as UV-VIS spectrophotometry (including derivative and multi-wavelength measurements), basic electroanalytical (potentiometric, polarographic and voltammetric) methods, fluorimetry, flow-injection analysis, etc. are accepted for publication in exceptional cases only, if a unique and substantial advantage over presently known systems is demonstrated. The same applies to the assay of simple drug formulations by any kind of methods and the determination of drugs in biological samples based merely on spiked samples. Drug purity/stability studies should contain information on the structure elucidation of the impurities/degradants.
