Abstract: The obtained extract from the roots of Petasitidis Radix belongs to the group of extremely complicated extracts due to appearance of a two-phase or three-phase solvent during the process of separation after the extraction process and the concentration, where is present pyrrolizidine which is a part of the group of toxic and poisonous materials. This is the reason why obtained extract, up to the phase separation, has an amount lower than 0.1 % in its content a phase of Pyrrolizidine, in order to remove the remaining amount of pyrrolizidine, by absorption. This is reached by using a different chemical adsorbent –of Lewatit, or bio-absorbent – diatomaceous earth, pharmaceutical Zeolite, etc. This dividing is done with separation of the phases, but not always is reached a complete separation, therefore a large amount is removed and is thrown in order to have a clear extract. In this paper work it was performed a pre-processing with Glycerin and lactic acid, a method which gives very good results and the extract losses are at minimum.
