Malaria is considered one of the health problems in many parts of the world. The objective of this work is to implement standardized extraction strategies using analytical methodologies of the Calophyllum brasiliense Cambess. for the validation of antiplasmodial potential in vitro. Using HPLC chromatographic and chemical characterization techniques (13C-NMR...

background spirulina is one of the most profitable known microalgae in the world, which is used as food and superfood. in the other hand, spirulina is a useful source of healthy components. it seems that the spirulina is transformable so that the introduction of a selectable marker is needed. objectives the purpose of this study was to determine a suitable selection marker for spirulina platens...

The current approaches to the quality control of herbal medicines are either compound-oriented or pattern-oriented, the former targeting specific components with some known chemical properties and the latter targeting all detectable components. The marker approach uses specific chemical compounds with known molecular structures, while the multi-compound approach uses both chemical compounds wit...

Chemical marker M-2 (4-hydroxy-5-methyl-3(2H)-furanone) can be used as a tool to evaluate heating patterns of foods in microwave sterilization. This research studied the kinetics of the M-2 formation in mashed potato as influenced by temperature and salt content. Mashed potato (83.12% moisture content) with 1.5% D-ribose was heated in the capillary tubes at four temperature levels. Chemical mar...

The furanosesterterpene variabilin was isolated from the sponge Sarcotragus. From a chemical point of view, the family Irciniidae has been the source of furanosesterterpenes, and especially variabilin is an important chemotaxonomic marker for the family Irciniidae.

Tumour markers are substances that are produced either by the tumour itself or by the body in response to the presence of cancer or certain benign conditions that can aid in the diagnosis of cancer. The subject of tumour markers is a broad one, and there is an abundance of data. A literature review of potential molecular markers relevant to oral neoplasia was undertaken in terms of a perspectiv...
