Answer to Question #109580 in General Chemistry for Daniel

Question

steps to seperate the active component of dongoyaro leaf use in the treatment of malaria

Answer 1

The active ingredient in neem leaves, called irodin A, is toxic to resistant strains of malaria.

Experiments have shown that one of Nima's components is gedunin, as effective against malaria as quinine.Tea and tree leaf extracts, leaf powder used in the treatment of malaria.

Dry leaves can fumigate rooms and disinfect them.

leaf extracts:

Various methods are used to obtain extracts: maceration (infusion), percolation (displacement), repercolation, countercurrent and circulation extraction, etc.

For extraction of medicinal plant materials, water, ethanol of various concentrations and other extractants are used, sometimes with the addition of acids, alkalis, glycerol, chloroform, etc

In the manufacture of liquid extracts from one weight part of the medicinal plant material, one or two volume parts of the extract are obtained.

The obtained extracts are defended for at least 2 days at a temperature of no higher than 10 ° C until a clear liquid is obtained and filtered.

Extracts for thick extracts are freed from ballast substances by precipitation with alcohol, the use of adsorbents, boiling and other methods, followed by filtration.

The purified extracts are concentrated by evaporation under vacuum to the proper consistency.

Dry extracts are obtained by drying thick extracts or directly from a purified extract using methods that ensure maximum preservation of the active substances - spraying, lyophilization, sublimation, etc.

In the United States, a method for the rapid extraction of valuable components from dried plant materials by extraction with water at a temperature of 40-60 C and the creation of a mixture of ultrasonic vibrations with a frequency in the range of 100-150 kHz is proposed. This method provides the extract with a high degree of transparency without loss of flavoring compounds and without components with an unpleasant bitter or astringent taste. At the same time, the extract is sterilized due to the action of ultrasonic waves.To intensify the extraction process, a cavitation-rotational method of obtaining extracts from spicy-aromatic plant materials is used, based on the use of a cavitation generator, which allows to increase the degree of dispersion of the raw material, while simultaneously carrying out accelerated extraction of dissolved substances from it. As a result, extracts were obtained that have significant biological value due to the increased content of phenolic compounds, amino acids, and minerals.

leaf tea

1. fresh flesh picking
2. cleansing, washing leaves
3. fermentation and temperature drying
4. the resulting raw materials are brewed with hot water and set up

In addition, neem leaves can be petetrated and diluted with honey.

He is referred to in the Vedas as a plant "curing all diseases." Therefore, be healthy!
