This study was conducted in the Physical Science Instrumentation Room, Physical Science Department, Cavite State University, Indang, Cavite and at the Standards and Testing Division, Industrial Technology Development Institute, Department of Science and Technology, Bicutan, Taguig, Metro Manila from September 1999 to February 2000. This study aims to extract and characterize the essential oil from camia rhizomes, leaves and stems. The clear, light yellowish color oil of the three camia parts was obtained by water distillation. The oil recovered from camia rhizomes obtained a percentage yield of 0.0861%.
On the other hand, camia leaves yield 0.0706% and camia stems yield 0.0611%.
The physical and chemical properties of extracted essential oil from camia are as follows; density = 0.6000 g/ml (rhizomes); 0.9000 g/ml (leaves); 0.7000 g/ml (stems); specific gravity at 25°C = 0.6012 (rhizomes); 0.9018 (leaves); 0.7014 (stems); acid value = 0.0370 mol/g (rhizomes); 0.0193 mol/g (leaves); 0.0134 mol/g (stems); saponification value = 0.0238 mol/g (rhizomes); 0.0161 mol/g (leaves); 0.0079 mol/g (stems); ester value = 0.0132 mol/g (rhizomes); 0.0032 mol/g (leaves); 0.0055 mol/g (stems). A chemical analyst at the Standards and Testing Division, Department of Science and Technology, Bicutan, Taguig, Metro Manila did thin-layer chromatographic analysis of oil. Alpha-pinene, citral and eugenol were found to be present in the extracted essential oil from camia rhizomes. On the other hand, «-pinene, citronellal, citronellol and geraniol were observed present in the extracted essential oil from camia stems. Citral, citronellal, citronellol and geraniol were likewise indicated to be present in the oil of camia leaves.
