What is percolation and maceration?

Definition. Maceration refers to the process of becoming softened by soaking in a liquid while percolation refers to the process of a liquid slowly passing through a filter.

What is percolation in extraction?

Percolation extraction is a conventional extraction method used in the processing of traditional Chinese medicines. After medicinal material powder is placed in a percolation tank, the extraction solvent is continuously added, and percolation extract is collected simultaneously. The percolation equipment is simple.

What is maceration process?

(i) Maceration. This is an extraction procedure in which coarsely powdered drug material, either leaves or stem bark or root bark, is placed inside a container; the menstruum is poured on top until completely covered the drug material. The container is then closed and kept for at least three days.

What is percolation in pharmacy?

1 : the slow passage of a liquid through a filtering medium. 2 : a method of extraction or purification by means of filtration. 3 : the process of extracting the soluble constituents of a powdered drug by passage of a liquid through it.

What is a percolation tincture?

Percolation tinctures are made by grinding a dried herb, moistening it with some of the solvent, then letting it sit for 12-24 hours to moisten and expand. It is then packed into a cone (not too gently, or too hard) and the rest of the solvent (alcohol/water) is poured over the top of the herb.

What is percolation in Homoeopathy?

The percolation is the most common procedure for the preparation of tinctures and fluid extracts. The percolator is a conical vessel with a top opening in which is placed a circular drilled lid allowing the pass of liquid and subjecting the materials placed on it to a slight pressure.

What is called percolation?

Percolate comes from a Latin verb meaning "to put through a sieve". Something that percolates filters through something else, just as small particles pass through a sieve. Water is drawn downward through the soil, and this percolation usually cleans the water.

What is infiltration and percolation?

The terms infiltration and percolation are often used interchangeably, however, percolation specifically refers to the movement of water within the soil, while infiltration refers to water entering the soil surface. The infiltration rate is the amount of water that enters the soil in a specified time period.

Why is percolation used?

Percolation can be used to predict water transport factors such as the rate of leaching, or the flow of materials into water. This is most often used in agriculture to determine the movement of fertilizers or the salt content of soil.

What is maceration and examples?

Maceration is, generally, to soften by soaking in a liquid. In biology, maceration is used to describe multiple actions. One definition of maceration is the breakdown of food into chyme during digestion. Skin maceration, or pruning, is the softening and breaking down of skin from being exposed to too much moisture.

What is maceration simple?

1 : an act or the process of macerating something especially : the extraction of a drug by allowing it to stand in contact with a solvent.

What causes maceration?

Excessive exposure to moisture can cause maceration, a serious problem for your skin. Skin maceration happens when your skin is broken down by moisture on a cellular level. Once this damage occurs, your skin is much more vulnerable to other types of problems and complications.

What is the principle of percolation?

Extraction that consists of passing a liquid (solvent) through a plant. Percolation is an extractive procedure that is conducted at room temperature and that literally means “pass a liquid through a solid material drop by drop.”

What is the difference between infusion and maceration?

Maceration involves extracting flavors by crushing or muddling. Infusion is the easiest. Put ingredients in a jar and fill with alcohol. Since ethanol is a solvent, if the ingredients have any natural oils, they are quickly absorbed and the spirit takes on those flavors.

What is maceration process in pharmaceutics?

Maceration is an extractive technique that is conducted at room temperature. It consists of immersing a plant in a liquid (water, oil, alcohol, etc.) inside an airtight container, for a variable time based on the plant material and liquid used.

What is percolation in the water?

Percolation is the movement of water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches ground water, which is water below the surface.

What is soil percolation?

Percolation is the downward movement of soil moisture through the vadose zone that is located between the root zone and the capillary fringe of the permanent groundwater table (Hill, 1979). Percolation is also called internal drainage (Hillel, 2004).

Is percolation and groundwater the same?

Percolation: similar to infiltration, but a deeper transfer of water into permeable rocks. Groundwater flow: the very slow transfer of percolated water through pervious (permeable) or porous rocks.

What is percolation in biology?

describes the process by which a material more fluid than soil, usually water, moves through soil. refers to the ability of soil to absorb water.

What is herb maceration?

Maceration: Maceration is a method of making extractions. It's the process of soaking the herb or plant matter in the menstruum, or solvent, for a period of time that varies based on the ingredients. Maceration allows a menstruum to soak up an herb's constituents.

How long should a tincture macerate?

You'll want to gently shake your tincture about once a day for the duration of the infusion, which should last at least three weeks. Keep in mind, the rate at which your extraction proceeds decreases with time, so most of the extraction is done within the first week.

How many types of percolation are there?

There are two types of percolation, depending how one views the lattice: site percolation and bond percolation.

What are the different stages of percolation?

MODIFIED PERCOLATION  Reserved percolation  Continuous hot percolation  Continuous cold percolation Reserved percolation: This type of percolation is done to get concentrated preparation.
