Extracts powder

The principal thing in connection with the employment of ionone is to discover its proper degree of dilution. In its natural state the body is so highly concentrated as scarcely to remind one of violets. This is the reason why it was placed in trade in the form of a 10 per cent, solution, and not in its pure state. This form has proved an exceedingly useful one. In using it for extracts, powders, sachets, etc., the solution must be further diluted and fixed with some orris oil, civet, and musk. ... 

Detailed information about carotenoids found in food or extracted from food and evaluated for their potential as food colorants appeared in Sections 4.2 and 6.2. We would like to mention some new data about the utilization of pure carotenoid molecules or extracts as allowed food additives. Looking to the list of E-coded natural colorants (Table 7.2.1), we can identify standardized colorants E160a through f, E 161a, and E161b as natural or semi-synthetic derivatives of carotenoids provided from carrots, annatto, tomatoes, paprika, and marigold. In addition, the extracts (powders or oleoresins) of saffron, - paprika, and marigold are considered more economical variants in the United States and European Union. 

A method for determining the caffeine content of regular and decaffinated green and roasted coffee beans and of regular and decaffeinated coffee extract powders, using HPLC, is specified in a British Standard Instruction.34 Caffeine is extracted from the sample with water at 90°C in the presence of magnesium oxide. The mixture is filtered and an aliquot purified on a silica microcolumn modified with phenyl groups. The caffeine content is then determined by HPLC with UV detection.35...

The zeta-potential present on the silica surface is changed by the cleaning, preconditioning, storage method, and use time. Therefore, it is important to keep the surface condition reproducible. Usually, herb drugs are made of several crude drugs, as extracts, powders, or pills. The components of herb drugs are so varied that their quality control is applied to just one or two of their index components. CE has been applied to the analyti-...

The chemistry of medicinal herbs is very complex. Not all the constituents present in the plant have therapeutic activity, some are poisonous e.g. pyrrolizidine and tropane alkaloids. Phytochemistry deals with study of chemical composition of the plant material (Phyto refers to plant). Plants are used in various forms varying from powders to extracts. Powder represents the drug in ground from and these types of preparations are considered to be crude. The Pharmacopoeia mentions standardised vegetable powders for therapeutic application.

The soluble fraction of the organic matter in carbonaceous chondrites can be accessed by extracting powdered meteorite samples with solvents of varying polarity. These extracts contain complex mixtures of discrete organic compounds that can then be purified further, for example by charcoal filtration, ion-exchange chromatography or sublimation, before analysis.
