Densitometric thin-layer chromatographic determination of artemisinin and its lipophilic derivatives, artemether and arteether.
A thin-layer chromatograpy (TLC) method is developed to analyze artemisinin (AT) and its derivatives, artemether (AM) and arteether (AE), using a silica-gel plate with a mobile phase containing pure chloroform. After development, all products are visualized after dipping in a 4-methoxybenzaldehyde dipping reagent of 1% (v/v) in an acidic solution of sulphuric acid (98%, v/v) and acetic acid (96...
متن کاملImmunodiagnosis of Human Fascioliasis by Elisa Using Excretory–Secretory Products as Antigen
Background: Different immunological methods are used for the serodiagnosis of Fasciola hepatica infections, however, they have limited specificity and/or sensitivity.Objective: To improve the specificity of ELISA using a partially modified method for preparation of excretory-secretory (ES) antigens.Methods: Studied groups were as follows: 75 patients with parasitological evidence of fascioliasi...
متن کاملExcretory/secretory products of anisakid nematodes: biological and pathological roles
Parasites from the family Anisakidae are widely distributed in marine fish populations worldwide and mainly nematodes of the three genera Anisakis, Pseudoterranova and Contracaecum have attracted attention due to their pathogenicity in humans. Their life cycles include invertebrates and fish as intermediate or transport hosts and mammals or birds as final hosts. Human consumption of raw or unde...
متن کاملApplication of thin-layer chromatographic zonal 14C-profile scans to the analysis of urinary constituents derived from lipids.
Thin-layer chromatography (TLC) has been a useful tool in the analysis of numerous urinary constituents; as in most applications of adsorption TLC, it is best used in conjunction with other chromatographic processes. The application of TLC to the resolution of polar urinary products derived from lipids is shown for the metabolism of a 14C-labeled fatty acid and a 14C-labeled glyceryl thioether....
متن کاملThin-layer Chromatography of Lipids
There has been a tendency to discount thin-layer chromatography (TLC) in recent years because of the availability of high-performance liquid chromatography (HPLC) methods that appeared to offer greater versatility and ease of quantification, amongst other reasons. However, TLC has made a comeback, largely because of the high reproducibility and lower costs of commercial pre-coated plates. It is...
