The quantity of menstruum required for two macerations are calculated as follows:. In this process solid ingredients are placed in a stoppered container with the whole of the solvent and allowed to stand for a period of at least 3 days 3 – 7 days with frequent agitation, until soluble amd is dissolved.

Maceration is a method of softening something while percolation is a method of filtering liquids through a porous material. Leave a Reply Cancel reply. Filtration is necessary to remove insoluble cell contents obtained during the pressing of marc.

Ques 5 What is reserved percolation? After extraction the marc is not expressed. maceratkon

Difference Between Maceration and Percolation

After maceration, peercolation and pressing of the marc, measured volume volume of liquid is obtained. The molecules will move through the boundary layer by molecular diffusionwith no mechanical mixing or movement. Nature of the drug.

The term, maceration, is also used in the preparation of the specimens from the skeleton. Cochineal from insect Coccus cacti.

Comparison between extraction method: Furthermore, percolation is carried out on basins where polluted materials are filled. Degree of size reduction. Hence, percolation regulates the effect of microorganisms in many products such as food and pharmaceuticals. Only pure solvents or constant boiling mixtures like alcohol-water pecolation be used for this purpose.

Belladonna extract is obtained from the leaves of the plant Atropa belladonna. Soxhlation process of extraction is used to. Moreover, maceration involves a number percolwtion biological and chemical processes. Especially, rainfall seeps underground via the percolation.

Infusion, Decoction, Expression, Maceration, Percolation

After dissolution the solid materails has to be strained off. Concentrated compound infusion of chirata. On further heating the menstruum vaporizes while the dissolved active constituents remain behind xnd the flask. This will increase the penetration power of the menstruum, so that there is complete extraction of the drug. The strong solution of active constituents of drug formed during maceration is displaced by the fresh menstruum when percolation process is started.

The marc is wrapped in cloth, is placed in the perforated inner vessel, which is enclosed in another vessel having an outlet for the expressed liquid.

It requires costly instruments which may not be cost effective. Maceration of Swedish Liqueur. Alcohol acts as a preservative, hence it may be dispensed after 24 hours also. The marc can be squeezed out of a fine muslin piece, when the quantity of the drug is very small.

Difference Between Maceration and Percolation –

Pefcolation main methods of leaching are maceration and percolation. Overview and Key Difference 2. Cost involve in size reduction i. Furthermore, maceration does not involve gravity while percolation occurs towards the gravity.
