Mild extraction methods for organic colorant analysis^Beta

Undertaking a search

This search tool allows a free text searches (e.g. author, journal, article title, colorant class, scientific name, common name, etc) and although wildcard searches using an asterisk (*) are not currently possible, the search is currently configured in such a way that entering part of a word will allow a wider search, e.g. entering ‘indigo’ will return all entries that refer to indigo, indigotin, indigoid, etc. If two words (or partial words) are entered, the search returns all entries where BOTH word appear in any field in the entry (i.e. the search operates as if the Boolean ‘AND’ terms were used).

If searching for a particular colorant, in addition to searching by the scientific name and common names, it is also possible to search by the colorant class. The following colorant classes are currently defined: Anthraquinone, Indigoid, Flavonoid, Carotenoid, Curcumoid, Tannin, Homoisoflavonoid, Isoflavonoid, Quinchalcone, Anthocyanin, Orchil, Alkaloid, Synthetic, Chalcone/aurone.

Extraction method

The extraction methods have been divided into the following basic groups and these terms can also be used as search terms either on their own or in combination with other terms. A summary of the method used in each case can be found associated with each article.

Search results

Clicking on any article will open a pop-up window containing the full details of the colorants investigated in the paper, the samples types studied and the extraction methods used. Again the results can be reordered by clicking on the column headers. Placing the cursor over any entry will provide ‘hover over text’ providing additional information, definitions or explanations of the categorisation used. To close this pop-up window click on the "X" in the top right hand corner (note it may be necessary to scroll back to the top of the window).

Notes

With some Internet Explorer set-ups, although these webpages display correctly, the search tool is unavailable; opening the webpage in one of the other modern browsers, Firefox, Chrome, Opera, etc. avoids this problem.
