Chapter II REVIEW OF RELATED LITERATURE AND STUDIES Review of Related Literature On mosquito larvae‚ the major larval habitats were anthropogenic‚ resulting from human behavior. According to the Journal of Vector Ecology (2012 p37) stated that “The management of insecticide resistance among malaria vectors needs urgent attention if insecticide-treated materials can continue to be used for malaria control.” Metarhizium anisopliae‚ a fungal pathogen of terrestrial arthropods‚ kills the aquatic larvae

Quercetin (2-(3‚4-dihydroxyphenyl)-3‚5‚7-trihydroxy-4H-chromen-4-one) is a flavonoid which is a group of pigments that give many flowers‚ fruits‚ and vegetables their colour (Askari et al. 2012). Before supplement use became more prevalent the nutritional status of an individual was determined by the contents of their diet‚ and many of the people with a high nutritional status typically consumed a high amount of fruits and vegetables. Fruits and vegetables are the primary dietary sources of quercetin

also a peak at 722 corresponding to an aromatic substitution. The experimental melting point range was measured at 128.7 °-131.9° which also consistent with the literatures melting point range at 130 °-132° for trans-9-(2-Phenylethenyl)anthracene. The TLC analysis furthermore corresponded with our results as it only showed one spot for the product indicating that it is in fact pure.3 References 1. Lindsay‚ Maria C.‚ and Sean P. Hickey.

A separatory funnel is used to separate the organic layer‚ and the product is recrystallized for TLC‚ GC/MS‚ and melting point analysis. Pre-Lab 1. What is the limiting reagent in step 1? What is the theoretical yield of amide 1 in figure 3? The amine is the limiting reagent. The theoretical yield is 4.81 grams of amide 1. 2. What is the theoretical

We began our research by treating chalcone 1a (??) with acetylacetone 2a (??) in the presence of morpholine as the base (??) in CH3CN at 80 ºC for 12 h. The reaction was monitored by TLC until the disappearance of the starting material and the formation of 1-(5-benzoyl-2-methyl-4-phenyl-2‚3-dihydrofuran-3-yl)ethanone 3a. this reaction mixture‚ containing the 2‚3-dihydrofuran 3a generated in situ‚ was treated with sulfur element (??) in the presence of base of morpholine (??) at 80°C and the desired

Percent yield was found by weighing the watch glass with the filter paper and subtracting the total from the original weight. The TLC test was conducted by placing sample products on a TLC plate. Next‚ the plate was put in solvent mixture of 80% heptane and 20% ethyl acetate. The solvent mixture was allow to rise ⅔ the height of the plate and then placed under UV light to observe the distance the samples traveled
