Membrane extraction techniques permit the application of classic liquid–liquid extraction (LLE) chemistry in a miniaturized way to various sample preparation tasks. The shortcomings of LLE are overcome as only very little organic solvent is used and there are no problems with emulsions. Disposable mat...
Retrieving information from the chemistry literature has received a lot of attention over the last decades9,10. One of the predominant goals is to mine information from patents, papers and theses, and save it as structured data in databases in order to make chemical knowledge searchable and enabl...

According to analytical chemistry, spinach is a source of violaxanthin and neoxanthin antioxidants that cannot be commercially produced [105]. Although they may be present, pigments such as carotenoids can be masked by chlorophyll in greenish vegetables such as spinach [106]. B-carotene, lutein, ...
