Methods of bio-oil extraction have been developed. The advantages of liquid extraction methods, compared to fast pyrolysis, are the low temperatures and the possibility of solvent recovery so that they are considered more environmentally friendly. Multistage extraction with a variety of different polarity solvents has produced higher nicotine levels. Bio-oil has nicotine, d -limonene, indole, and pyridine as the main content. Tobacco bio-oil has certain toxical issues, especially due to the nicotine content that can be very dangerous. However, bio-oil passes acute toxicity tests and does not contain dangerous residues such as carbamate, organochlorine, organophosphate, nor heavy metals. Bio-oil is needed for further applications, especially as biopesticide or medicinal purposes with very special precaution. Bio-oil from tobacco plants is powerful against several bacteria and fungi. Plant insects can also be suppressed by using diluted bio-oil.
