Introduction:
In the previous paper we confirmed the presence of microbiological, inorganic and organic pollutants in home-made preserves of the poppy straw extracts – “compote”. These pollutants may influence its toxicity, however, are lacking of proper experimental studies. The authors have decided to develop the method of “compote” treatment and to determine and to compare LD50 dose for its treated form, raw form and standard morphine solution.

Material and Methods:
The research material was poppy straw extracts delivered by law enforcement authorities. Concentration of opiates in raw “compote” was determined using the high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS). Secured “compote” (1000 ml) was cleaned from plant“s ballast and other contaminations. LD50 was determined according to Litchfield-Wilcoxon method with reference to morphine. In the research thirty six 3-months-old, 200–250 g, male Sprague-Dawley rats were used. The animals were injected intraperitoneally once with appropriate extracts in three diversified doses.

Results:
Calculated LD50 doses of acute intraperitoneal toxicity were: for the raw extract – 83.8 mg/kg body weight; for treated extract – 51.9; for morphine hydrochloride’ solution – 61.1.

Conclusions:
The lowest value of LD50 for treated “compote” is attesting of its acute toxicity in comparison to the raw “compote” and morphine solution. The developed method of treating the “compote” allows for the reduction of pollutants, so it may be applied in the experimental research of both forms of drugs.
