Medicinal plants can be important therapeutic alternative, however microbiological contamination of plants represent a problem to be solved before the production. The technologic process of raw material has many stages, generally, adverse to microbial growth, but its complete elimination depends on the initial and work condition utilized. The aim of this work was to verify the microbial contamination of Phyllanthus niruri aerial parts and derivatives products, such as extractive solution (SE) and spray dried extract (PSA) with the purpose of evaluating the decrease of the contamination after the decoction and the spray dry. The microbiological analysis of the products was performed by total plate count and MPN coliform. The results showed that the contamination of the products was below the limit maxim. The contamination in the SE was significantly lower than in the plant and this fact suggest that the decoction was responsible for a reduction of 98,3% of the initial contamination. On the other hand, the PSA contamination was similar the SE thus suggesting that the spray dry did not affect the microorganisms present in the initial product.
