Heydari et al eventually liquid. Although some of our data collected was lower than expected, we still accomplished what the lab set out to do, which was to extract limonene oil from orange peels. Limonene is spotted in concentrations in the range to 9700ppm which is 0.97% by weight in peels of citrus fruits (Organic Chemistry Experiment2017). To begin the isolation of D-limonene, a The antifungal activity in terms of zone of inhibition and minimum inhibitory concentration (MIC) of the essential oil was tested against ten food borne fungal strains and ten bacterial strains. A terpenoid is a compound which has a skeleton based on theskeleton of 2-methyl-1,3-butadiene, commonly known as isoprene. Volume of Alcohol 150.00 300.00 150.00 Used/cm^3 This was done with 10.01g of orange peel and 50mL of water.
