FLUID EXTRACTS AND EXTRACTS Flashcards
Fluid extracts are made by
Percolation
3 variations of percolation in fluid extracts
Process A
Process B, C, E
Process D
Percolation method than can be modified for fluid extracts that must be assayed
Process A
An alternative for process A in which percolation is conducted on a column of drug much greater in length than in diameter
Process E
Boiling Water is used as the menstruum, alcohol being added as a preservative to concentrated percolate
Process D
Three forms of extract
Semiliquid (liquid)
Pillular (solid)
Powdered (Dry powders)
Consistency of semi-liquid extracts
Syrup
Consistency of pillular extracts
Plastic
Extract which has no intention to remove all of the solvent
Semi-liquid extracts
Extract which has an intention to remove nearly or almost of the solvent
Pillular and Powdered extracts
Uses two menstruum
Process B
Uses pressure and suitable for commercial use
Process C
Alternative for Process A
Process E
Percolation process which sets aside the first 85% of the percolate then collects the weak percolate until exhaustion
Process A
