Modern method of extraction (T. Y. B. Pharm) As per PCI Syllabus • IN this video explained in details • MODERN METHODS OF EXTRACTION • EXTRACTION • Extraction is defined as the process of isolation of soluble material from an insoluble residue, which may be liquid or solid, by treatment with a solvent. • Mechanism of extraction • Extraction Methods • Infusion • Digestion • Decoction • Maceration • Percolation: is a continuous flow of the solvent through the bed of the crude drug material to get the extract. • Modified Percolation • Continuous Extraction (Soxhlet apparatus) • Soxhlet apparatus is one of the most important apparatus used in Pharmacognosy and botany practical class. Soxhlet apparatus is used for the extraction of crude drug for evaluation of its phytochemical and medicinal importance. Soxhlet apparatus is made up of glass assembly of borosilicate type. Soxhlet apparatus consists of 04 main parts or section- (1) Round bottom flask (2) Drug chamber with vapour and syphon tube (3) Condenser unit (4) Water pipe. Soxhlet apparatus is also known as a hot extractor of crude drugs. The drug which is to be extracted is firstly converted into coarse powder and then filled into a thimble. In Soxhlet apparatus thimble is a pocket made up of either filter paper or muslin cloth, which allows only solvent to pass from and it does not allow drug particle to pass with the solvent used. After adding the drug to crude drug chamber the appropriate solvent is introduced through the solvent inlet over the condenser. this solvent comes down at the round bottom flask, a heat by hearting device coverts solvent into vapour and this vapour travels through vapour tube and at the bottom of the condenser in Soxhlet apparatus it condensed and converts into the solvent and again fall down over the crude drug and the level of solvent is increased. When it increases in sufficient quantity that comes down to the round bottom flask via syphon principle and this steps continues till solvent becomes concentrated. This ends the process of extraction. • Advantages • Disadvantages • Large Scale Extraction • Super Critical Fluid Extractor (SCF) • SCE applications in Pharmacognosy • Sublimation process the compound if subjected to heating, changes from solid state to gaseous state directly without passing through a phase of liquid. • Aqueous Alcoholic Extraction by Fermentation • Counter-current Extraction • Ultrasound Extraction (Sonication) • Phytonics Process • Factors Affecting Choice of Extraction Process • Ideal properties of the solvents • T.
