The properties of the new generation of fluorocarbon solvents have been applied to the extraction of plant materials. The core of the solvent is 1,1,2,2-tetrafluoroethane, better known as hydrofluorocarbon-134a (HFC-134a). This product was developed as a replacement for chlorofluorocarbons. The boiling point of this solvent is -25° C.

Which solvent is best for oil extraction? If you wish to capture the lipophilic properties of plants, a cheap, easy and useful solvent for their extraction is botanical oil. Ideally, use a neutral oil with barely any scent as the carrier and extraction oil. Typical oils used for maceration include sunflower, sweet almond and safflower.
Conventional extraction techniques Maceration. Maceration is a simple extraction method that involves soaking the plant prepared raw material in a coarse or powder form in a …
Human beings have relied on herbs and medicinal plants as sources of food and remedy from time immemorial. Bioactive compounds from plants are currently the subject of much research interest, but their extraction as part of phytochemical and/or biological investigations present specific challenges. Herbalists or scientists have developed many …
Hence, various crucial factors of extraction methods like the proper selection of plant parts, solvent, pressure, temperature, and time of process can affect the method's success. The classical techniques of plant extraction like maceration, percolation, Soxhlet extraction are used in 'small-scale' manufacture or research settings.
