The ultimate goal of my research is to discover the alternative agents from natural products for the treatment. I identify the bioactive compounds from plant extracts and study the underlying mechanism of many pharmacological activities by using in vitro model. I am interested in many activities including anti-oxidative, anti-hyperglycemic, anti-hyperlipidemic, anti-glycation, anti-apoptosis, anti-inflammatory, and anti-microbial activities.

Now I am studying the anti-hyperglycemic and anti-hyperlipidemic activities of Thai plant extracts. I identify the phytochemical compounds by using high performance liquid chromatography (HPLC). I also study the mechanisms of these extracts to inhibit the digestive enzymes of carbohydrate and lipid to delay the processes of digestion and absorption by using in vitro. In addition, I study the mechanism of glucose uptake in skeletal muscle cells. I also study the insulin secretion activity in pancreatic beta-cells. Moreover, I have another research to study the anti-apoptosis activity of cinnamic acid and its derivatives in pancreatic beta-cells. In this study, I use methylglyoxal as an inducer for cell apoptosis. Many methods are used for this research including cell viability assay (MTT assay), formation of reactive oxygen species, caspase-3 activity, and flow cytometry to detect apoptotic cells.
