Comparison of different concentrations of Scrophularia striata and Prosopis fracta extracts on removing of parasites in raw vegetables from Ilam province

Parasitic diseases are considered as the most prevalent problems in developing countries. The consummation of raw vegetables is the main way for transmission of parasitic infections to human and other animals. The aim of the present study was to compare the effects of different concentrations of Hydro-Alcoholic extract of Prosopis fracta and Scrophularia striata on removing of parasites from raw vegetables. In this experimental study, plant samples were collected from the mountainous areas close to Ilam and Mehran. Samples were dried in the shade; the powder was prepared with the help of an electric grinder. Hydro-Alcoholic extract of plants was obtained using Soxhlet apparatus and ۵۰% ethanol. Raw vegetables were washed in ۰/۰۱, ۰/۱, ۱ and ۲% concentrations of S. striata and P. fracta extract, and with contact time of ۱۵ minutes. Then the samples were removed and after ۲۴ h, remaining washing solution of each of the solutions was centrifuged. Then the slides were prepared from sediments and were examined with light microscope. Results show that the maximum parasites removing by P. fracta and S. striata extract was obtained at ۱% and ۲% concentrations, respectively. Also, in comparison between these two concentrations, ۲% extract of S. striata is more effective in parasite removing in vegetables. Due to the effective role of Hydro-Alcoholic extract of S. striata and P. fracta to remove parasite from raw vegetables, these two medicinal plants can be considered as an effective and new solution for proper washing of vegetables, and considered them as natural detergent and cleanser that have a good disinfectant power of edible fruits and vegetables.
