Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted

Theoretically‚ the spinach extract at 18oC should have a faster rate of reaction than the 5oC extract because higher temperature allows substrates to move more rapidly hence increases the chance of collision with the enzymes. Moreover‚ the experiment was low in accuracy as the class average varied significantly

#47 The Feasibility of Adelfa Extract as Pesticide Vivencio C. Fuentes Jr.‚ Razelle Angela B. Camitan‚ Honey Jane T. Dela Cruz ABSTRACT The project aims to test the feasibility of extracts from the adelfa plant as pesticide. The leaves were cut from the stem and then subjected to steam bath. Soxhlet apparatus was used for extraction; methanol was used as solvent. The extract was then distilled‚ and diluted into 4 containers to obtain concentrations of 100%‚ 75%‚ 50% and 25%. There were
