| Summary: | The traditional Thai herbal compress is composed of six different types of herbs including Ginger (Zingiber cassumunar), Turmeric (Curcuma longa Linn.), Soap Pod (Acacia concinna), Kaffir lime (Citrus hystrix), Lemongrass (Cymbopogon citratus), and Tamarind (Tamarindus indica Linn.). Herbal compress is used in treatment of Thai traditional massage to relieve the body pain and muscle strains. The objective of this work is to perform chemical profiling and extraction modelling of herbal compress obtained from solvent extraction method. The kinetic models, The second order and Fick‘s second law, representing the extraction behaviors of bioactive compounds were constructed to fit with experimental data of solvent extraction. Under tested condition, the extraction equilibrium was reached after 360 min and the second-order model gives the best fit for the experimental data with high coefficients of correlation (R2 = 0.9927). Additionally, chemical profiling analysis showed that the amounts and variations of bioactive components in drying-pretreated herbal compress were more abundant than that of untreated sample. This finding could be applied further for preparation and production of traditional Thai herbal compress in the industrial scale.
