- Analysis (qualitative, quantitative) of active ingredients, impurities in drugs, cosmetics, functional foods using a broad range of analytical methodology [examples include Chromatography (HPLC-UV, HPLC-PDA, HPLC-ELSD, HPLC-MS/MS, GC, TLC), Ultraviolet Spectroscopy, Infrared Spectroscopy].- Standardization of pharmaceutical products (plant-based medicines, functional foods, cosmetics, medicines from insects), includes development and validation of new analytical method for quality control using reversed-phase HPLC with C18 column, amino-bonded silica gel column, cation-exchange column. - Validation new analytical method (determine calibration curve, linearity, LOD, LOQ, accuracy, precision, stability).- Optimization of extraction method using one-factor-at-a-time methodology, Box-Behnken design and response surface methodology with support of Design Expert program or R program.- Multivariate analysis including Hierarchical cluster analysis (HCA), Linear discriminant analysis (LDA), Principal component analysis (PCA), and Partial least square discriminant analysis (PLS-DA) using R program.- Evaluate reference standards materials that was synthesized chemically or extracted from plants, marine invertebrates and insects for quality control purpose.- Analysis of active ingredients in rat plasma samples using HPLC-MS/MS for pharmacokinetic/ bioavailability study.
