Study on extraction of long pepper extract, with a solvent such as methanol ethanol. The chloromethane and water by soaking in solvent for a period of 48 hours, found that when the crude extract was tested highly killing mealworm, taking crude extract was to meet Zhang at the ratio 1/80, 1/40, 1/20 and 1/10% w/v, and then sprayed on the worms, worm count of the dead to find out the value of each type of extract IC50. IC50 values was found to be equal to 4.00 and 4.50% 0.00, 2.20, w/v, respectively, to bring value to the event pages with long pepper in arin, the TLC Rf value techniques of extracts. Has a value of 0.00 0.60 0.57 and 0.68, which, as close to the event's page on the show that arin blossom with the event page with arin and the quantity of education event in the arin page extracts using HTLC found that percent of the Piran-arin page in each type of extract is 1.2143, and 1.5017 0.9107, 0.00, respectively.
