Determination of microbe content in the Centella asiatica simplisia and extractbefore and after pasteurization process by Gamma-rays with variation of dose has been evaluated. The radiation process into the simplisia and extract significantly decreased of microbe content from > 104 to < 10 - 100 colonies. For the various radiation dose at 2.5 – 10.0 kGy, the decreased microbe content in the extract to < 10 colonies. The result showedthat the radiation to extract was more effectively than to simplisia, in the decrease of microbe contaminant. The result of TLC analysis showed that the radiation was not affected to the active compound in extract.
