Background: D. hispida can be used as a painkiller, rheumatic drugs and antioxidant. Based on its medicinal properties, D. hispida can be used as a traditional medicine that must be guaranteed on quality, safety and benefit. Therefore, standardization is needed. This aim of this study was to obtain some specific and non-specific parameter of simplicia and ethanolic 70\% extract of D. hispida tubers from three different regions. Materials and Methods: The samples were macerated by using ethanol 70\%. Results: The results showed that the specific parameters of D. hispida simplicia; the total water soluble extract was 11.25-16.20\%; the total ethanol soluble extract was 6.42-9.39\%; the chromatogram profile was obtained by using thin layer chromatography in toluene-ethyl acetate-chloroform (5:1:4) mobile phase with β{\textendash}sitosterol as standard, the total phenolic content was 2.15{\textendash}2.50 expressed in mgGAE/g simplicia. The non-specific parameters of D. hispida simplicia; the total loss on drying was 10.53-12.40\%; the total ash content was 5.81-5.94\%; the total acid insoluble ash content was 0.20-0.22\%. The specific parameters of D. hispida extract; the total phenolic content was 10.30-11.72 expressed in mgGAE/g extract. The non-specific parameters of D. hispida extract; the total water content was 10.27-10.47\%; the total ash content was 2.84-2.93\%; the total acid insoluble ash content was 0.14-0.19. Conclusion: conform the parameters.
