Background: The mixtures of Derris scandens (DZSS) formula is a Thai traditional medicine, which consists of 4 medicinal plants, including Derris scandens (Roxb.) Benth. (D) Zingiber cassumunar Roxb. (Z), Suregada multiflora Baill. (S) and Siphonodon celastrineus (S). The DZSS formula has been used in an oral dosage form for the treatment of muscle pain. However, the phytochemical profiles and the pharmacological activities of the combined DZSS formula have not been clearly investigated. Objective: This study aimed to investigate the phytochemical profiles and the anti-inflammatory activity of the DZSS formula. Materials and Methods: The ethanolic extracts of the formula (50\% and 95\% ethanolic extracts) were prepared by using soxhlet extraction and which were analyzed by using HPLC. The anti-inflammatory activity of the DZSS formula was tested for its inhibitory effect against nitric oxide (NO) production in Raw 264.7 cells macrophage.The cytotoxic effect of the formula was determined by using the MTT assay. Results: The 95\% ethanolic extract of the DZSS formula exhibited a pronounced anti-inflammatory activity with the IC50 of 40.08 {\textpm} 2.78 μg/mL. The 95\% ethanolic extract possessed a more potent anti-inflammatory activity than that of the 50\% ethanolic extract and with no cytotoxicity. HPLC analysis indicated that the 95\% ethanolic extract also had a higher yield of genistein and compound D, which are obtained the amount of 0.71 {\textpm} 0.00 and 18.89 {\textpm} 0.24 mg/g extract, respectively. Conclusion: Our data suggest that the 95\% ethanolic extract of the DZSS formula possessed a significant anti-inflammatory activity but which is still required to investigate about biological activity in vivo and clinical study.

Introduction: The rhizome of Enhalus acoroides (L.f.) Royle is used in traditional medicine for treatment of many diseases e.g. muscle pains, wounds and stomach problems where pharmacognostical studies are lacking. Many chemical constituents; luteolin, apigenin, luteolin glycosides, stigmasterol, daucosterol have been reported. The aim of this work was to perform a pharmacognostical evaluation. Methods: Macroscopical, microscopical and physicochemical parameters were assessed. Results: E. acoroides has characteristic morphology. Microscopical studies indicated the presence of vessels, fiber, parenchyma cells, sclereids, tracheids and trichomes. Physicochemical parameters of E. acoroides rhizome; foreign matter, loss on drying and total ash content were measured. As well as chemical investigation through TLC and HPLC were specified. Conclusion: The present study of E. acoroides rhizome provides useful information that can serve as a diagnostic tool for the standardization of E. acoroides and will be helpful in characterization of the crude drug in the market.
