Abstract:
The scope and applications of a traditional as well as new oil depends upon its physical and chemical properties. Drying nature, saturation, chemical composition etc. are some of parameters to classify the oils into different categories. The Koettstorfer number, acid value and ester value of seed oil of Ocimum americanum known as ran Tulsi with some other physic-chemical values were determined and compared with standard values with a comparative view. The current paper deals with the extraction and characterization of Ocimum americanum, seed oil using n-Hexane as solvent. The plant is widely distributed in waste lands and also in our Jodhpur zone. The seeds were found to contain 8% oil .The percentages of glycerol present in triglycerides were also calculated with the help of acid value, and the percentage of free fatty acids were calculated from the ester value. An idea about the amount of NaOH, commercially known as lye needed to make sodium salt of soaps were also calculated from KOH to NaOH conversion scale.
