Abstract: ARGONZA, LALAINE ACOSTA, "Extraction and Characterization of Essential Oil from Cashew Shells (Anacardium occidentale Linn.)", B.S. Thesis, Bachelor of Science in Chemistry, April 2001. Cavite State University, Indang, Cavite. Adviser: Mrs. Ma. Corazon V. Herrera. This study was conducted at the laboratory room of the Department of Physical Sciences, Department of Animal Sciences, Cavite State University, Indang, Cavite and at the Forest Products Research and Development Institute, UP Los Batios, Laguna. Generally, this study aimed to extract and characterize essential oil from cashew shells. Specifically, it aimed to: 1) extract the oil from cashew shells; 2) determine the physical and chemical properties of the extracted oil; and, 3) identify the chemical constituents and the importance of the extracted oil using Thin-layer chromatography and Infrared spectroscopy. One kilogram of cashew shells was bought from Antipolo, Rizal. The oil was extracted from cashew shells using petroleum ether through Soxhlet extractor. Several physical and chemical tests such as specific gravity, solubility tests, acid number, saponification number, ester value, TLC analysis and infrared spectroscopy were conducted on the extracted oil. Obtained values from different tests were: 49.28 % yield, 45.05 acid number; 88.49 saponification number, 43.44 ester number. The extracted oil was found insoluble in water but soluble in organic solvents such as benzene, ethyl alcohol and ether. Results obtained show that the sample produces two spots on TLC analysis. The Rf values of the two spots were 0.309 and 0.527, respectively while the standard (salicylic acid) was 0.582. Based on the literature, the two possible constituents present on the cashew shell oil are cardol and anacardic acid. Anacardic acid is more acidic than cardol, which when compared with standard, produces almost the same spot on the TLC. Results showed that the FT-IR spectra of the sample contained the functional groups O-H (alcohol), C-H (aliphatic), C=0 (aldehydes and ketones), C=C (alkenes), C-0 ( esters) and =C-H out of the plane bending with the wavenumber (cm-1) of 3361, 3010- 2852, 1647, 1447, 1160 and 988-701 respectively.
