2.1 Test materials: The essential oils of Curcuma longa (Zingiberaceae) rhizomes, Pogostemon heyneanus (Lamiaceae) leaves and Zanthoxylum limonella (Rutaceae) fruits were obtained from a commercial oil extraction plant in Assam, India. DMP was supplied by High Purity chemicals, New Delhi, India while DEPA was obtained from Defence Research and Development Establishment, Gwalior, India. Four concentrations (5, 10, 20 and 30%) of the essential oils, their mixtures, DEPA and DMP were prepared in…

Results: Figure 1; Repellent activity in percentage of the volatile extract of C. sinensis, C. limon, C. aurantifolia and positive control on Camponotus nearcticus. The activity was generally high on C. nearcticus with positive control recording 100% activity, C. limon having 95% and C. sinensis having the lowest activity of 82.5% activity. Figure 2; Observed percentage lethal activity of the volatile extracts on C. nearcticus at five concentration points after 180 minutes of exposure…

Maci Mullins CHEM2130-001 12/8/2017 A Wittig Reaction of trans-Cinnamaldehyde Statement of Question: What is the stereochemistry in the Wittig product, and why is it formed? Hypothesis: There were two possible stereochemical outcomes for this experiment, either cis, (E,Z), or trans, (E,E). The cis product, (E,Z), would form if the double bond and phenyl group added to the same side. The trans product, E,E), would form if the double bond and phenyl group were to add to the opposite sides.…

How was the Volstead Act applied to American citizens differently for the African American then the White Americans? It was January 17, 1920 around 12:01 am, when the United States of American enacted the Volstead Act, make the US officially “dry.” The 18th amendment which was ratified in 1919, but enacted in 1920, outlawed the transportation, sale, or manufacture of any intoxicating liquor from or to the United States of American. Throughout our history, the ratification and enactment of the…

Wang et al. (2015) formulated a solid dispersion to improve the solubility and bioavailability of Ginkgo biloba extract (GE) through hot melt technology. The polymer studied were Kollidon® VA64/Kolliphor® RH40 (85:15) and the extrusion was carried out at 120-125⁰C with 100 RPM with 25% drug load. DSC and XRD studies confirmed the amorphous conversion of the GE and the dissolution carried in 250ml of 0.1N HCl showed that the dissolution of solid dispersion of GE was significantly improved (2-3…

1.2.2. Physical Properties Methyl ethyl ketone is a clear, colourless fluid that is less viscous than water and has a somewhat acute odor that smells most of the ketones and is described by some as being similar to Boerscot. Compared with acetone it is less volatile and less soluble in water (about 27.5g / 100mL at room temperature). It is a solvent used for extracting gums and oils from plants and cleaning the remnants of metal and glass, so why often a cleaner or ingredient is found 1.2.3.…

Microwave (MW) assisted Esterification of Benzoic Acid (BA) offers the advantage of transformation of energy and heating throughout the volume efficiently in a shorter period and eliminates the use of excess solvent, during the course of reaction. The present study aims to assess the conversion and selectivity for the production of methyl benzoate compounds by esterification of benzoic acid using microwave irradiation. Effects of operating parameters such as reaction time, feed composition,…
