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. ... The plant material can be used fresh or dry based on the desired product.

How do you perform a maceration?

(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 maceration process?

Maceration is the process by which organized tissue is transformed into a suspension of intact cells, resulting in pulpy products used as base material for pulpy juices and nectars, as baby foods, and as ingredients for dairy products such as puddings and yoghurts (Pilnik and Voragen, 1993; Khatri et al., 2015).

What material is used for maceration?

Maceration is the winemaking process where the phenolic materials of the grape—tannins, coloring agents (anthocyanins) and flavor compounds—are leached from the grape skins, seeds and stems into the must.

What are the different maceration processes?

The wine samples were obtained by applying five types of maceration: Classic maceration (V1; S1), Thermo-maceration (V2; S2), Microwave maceration (V3; S3), Ultrasound maceration (V4; S4) and Cryo-maceration (V5; S5).

Why is maceration done in closed vessel?

A wide mouthed bottle or any other container which can be well stoppered can be used for maceration process. A closed container is essential to prevent the evaporation of menstruum which is mostly concentrated alcohol. Otherwise this may lead to variation in strength as no adjustment in volume is made.

What is maceration in pharmaceutics?

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 is extraction process?

Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed (Phase 1), by means of a liquid immiscible solvent (Phase 2). ... Afterwards in order to regenerate the solvent, another separation step (e.g. distillation) is finally required.

What is Foetal maceration?

Fetal maceration takes place upon intrauterine fetal death (IUFD) and is a process characterized by enzymatic autolysis of cells and degeneration of connective tissue leading to skin discoloration, desquamation with formation of bullae and eventually skin peeling, as well as edema of the outer and inner organs with ...

What are the types of extraction?

Types of extraction

• Liquid–liquid extraction.
• Solid-phase extraction.
• Acid-base extraction.
• Supercritical fluid extraction.
• Ultrasound-assisted extraction.
• Heat reflux extraction.
• Mechanochemical-assisted extraction.
• Maceration.

How are chemicals extracted from plants?

Some people extract the plant material starting with hexane (or petroleum ether), and follow that with solvents of increasing polarity (ethyl acetate, ethanol, and water, for example). These extracts are then subjected to column chromatography. Others extract into alcohol followed by column chromatography.

How are enzymes extracted from plants?

The extraction process consists of three parts: > Grinding, to reduce the size of the plant and increase the contact surface available for the enzymes. > The enzymatic reaction takes place in a tank stirred and thermostated in the presence of water.

What is percolation method of extraction?

Percolation is an exhaustive extraction procedure, by which all of the soluble constituents are completely removed from a comminuted plant material, by extracting the crude drug by fresh solvent.

Why is maceration aseptic?

Maceration is the process of aseptic autolysis that occurs as soon as an undelivered infant dies and considered to be the sign of intrauterine fetal death. It arises secondary to the effects of autolytic enzymes and occurs in the sterile environment [4].

What is the difference between stillbirth and IUFD?

The Perinatal Mortality Surveillance Report (CEMACH)3 defined stillbirth as 'a baby delivered with no signs of life known to have died after 24 completed weeks of pregnancy'. Intrauterine fetal death refers to babies with no signs of life in utero.

What is intrauterine death?

Intrauterine fetal demise (IUFD) is the medical term for a child who dies in utero after the 20th week of pregnancy in the second trimester. Although there is no agreed-upon time, most doctors deem the death to be an IUFD if it occurred after 20 weeks of gestation.

Why do we do extraction?

Surgical extraction procedures are performed when the tooth cannot be easily accessed. This happens when the tooth has not fully erupted or when the tooth has been broken under the gumline. In this procedure, the dentist may perform incision to elevate the soft tissues covering the tooth.

What is extraction and Galenicals?

 GALEN a Greek pharmacist of Rome who described various methods of extracting the crude drugs for the first time & hence the branch dealing with the extraction of plant & animal drugs is known as Galenical pharmacy & the products as Galenicals.

What is extraction process in pharmaceutics?

Extraction refers to processes for the isolation of the active ingredients from drug material. This may be by physical means or by dissolving in a suitable menstruum (liquid solvent eg. water or alcohol). ... Infusions are prepared by simply soaking a drug in water for a specified time.

What is maceration and infusion extraction method?

Infusion. Fresh infusions are prepared by macerating the crude drug for a short period of time with cold or boiling water. These are dilute solutions of the readily soluble constituents of crude drugs. Digestion. This is a form of maceration in which gentle heat is used during the process of extraction.

What is the significance of maceration?

Macerate: To soften tissues after death by soaking and by enzymatic digestion, as occurs with a stillborn. The word "macerate" comes from the Latin "macero" meaning to soften by soaking (in a liquid).

What is difference between decoction and maceration?

Maceration is the extraction of a active in a solvent with shaking or stirring at room temperature. On the other hand, decoction is a method of extraction that results from placing a matrix in a menstruum (solvent) that is then heated to boiling.

What is the difference between percolation and infiltration?

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.
