Author(s): Girdhar Sanjay Shendre, Peddireddi Sivakrishna
Abstract: A large number of herb materials contain Essential Oils with extensive bioactivities. Acknowledging the importance of plants and its Medicinal & Agricultural value, extraction of Essential Oil had been done using Steam Distillation method. In this project Steam Distillation was used to extract oil from different plant materials like eucalyptus leaves, curry leaves, hibiscus leaves, lemon leaves, marigold flowers, Rose flowers, orange peels etc. Research has confirmed centuries of practical use of essential oils, and we now know that the 'fragrant pharmacy' contains compounds with an extremely broad range of biochemical effects. Essential oils are so termed as they are believed to represent the very essence of odor and flavor. The recovery of Essential Oil (the value-added product) from the raw botanical starting material is very important since the quality of the oil is greatly influenced during this step. There are a variety of methods for obtaining volatile oils from plants. Steam distillation method was found to be one of the promising techniques for the extraction of essential oil from plants as reputable distiller will preserve the original qualities of the plant. The distillation was conducted in Extraction unit in which boiling, condensing and decantation was done. Which gives valuates Essential Oil qualitatively and quantitatively. Volume of Essential Oil obtained was changing w. r. t. temperature and time of heating.
