Some studies on assessment of physico-chemical properties of extracted essential oil

Abstract

Patchouli (Pogostemon cablin) is an aromatic crop, belonging to the family Lamiaceae and is commonly known as Patchouli. Patchouli oil can be processed in food and perfumery industry of commercial importance. The knowledge about physico-chemical properties of any biomaterial is essential and to produce good quality oil that can compete with the Indonesian oil. improving the quantity and quality of Patchouli oil with different package of practices, Pilot scale study for enhancement of patchouli essential oil quantity and quality using biotransformation process. In the present investigation, some studies on the physico-chemical properties like Density, refractive index, acid values and ester values for oil extracted from the different sample of Patchouli oil were carried out. 2, 4, 6 and 8 days was found 0.970, 0.972, 0.973, 0.976 0.980 and 0.981 g/ml; 1.5098, 1.5070, 1.5029, 1.5024, 1.5008 and 1.5002; 3.65, 3.07, 3.17, 3.65, 3.77 and 4.40; 9.76, 8.77, 7.71, 6.14, 3.75, and 3.06 respectively for treatment with Aspergillus foetidus, 2, 4, 6 and 8 days was found 0.970, 0.972, 0.974, 0.977, 0.981 and 0.984 g/ml; 1.5098, 1.5070, 1.5024, 1.5014, 1.5023 and 1.5008; 2.65, 3.07, 3.12, 3.67, 3.70, and 4.95; 9.76, 8.77, 4.88, 3.28, 3.71 and 3.11 respectively., treatment with Penicillium citrinum, 2, 4, 6 and 8 days was found 0.970, 0.972, 0.978, 0.981, 0.986 and 0.989 g/ml; 1.5098, 1.5070, 1.5029, 1.5018, 1.5014 and 1.5014; 2.65, 3.07, 3.14, 3.40, 3.66 and 4.25; 9.76, 8.77, 7.46, 6.11, 5.61 and 5.60 respectively for treatment with Trichosporon asteroids
