              Extraction
      ▪The process of extraction is a generally
      ▪accepted method of the active 
      constituents.
      ▪• Extraction will remove only those 
      substances which can be dissolved in the 
      liquid known as solvent.
              Extraction
      ▪• The undissolved portion of the drug that 
      remains after the extraction process is 
      completed is known as the marc.
      ▪• The product of the extraction process is 
      known as the extractive and is usually a 
      mixture of substances.
              Extraction
      ▪• Usually drugs are grinded before 
      extraction to decrease particle size and 
      increase surface area available for solvent 
      to extract the material, and hence 
      increasing the efficiency of extraction.
           Types of extracts
      ▪• Dry extract: all the solvent has been 
      removed.
      ▪• Soft extract: contains 15-25% residual 
      water.
      ▪• Fluid extract: one part of the crude drug 
      is contained in one or two parts of the 
      extract.
