Evaluated is the use of thin-layer chromatography (TLC) to determine the quality of paracetamol tablets marketed in Bangladesh. The procedure was carried out using a cheap and rapid TLC method developed by the U.S. Food and Drug Administration. Reported also is a semiquantitative specific spot test for screening paracetamol tablets. The results obtained indicate that, of the 38 brands tested, t...

Decoction and 75% ethanolic extracts from the leaves of Acanthopanax trifoliatus (AT) and Toddalia asiatica (TA) were spectrophotometrically examined for antioxidant activity and phenolics content. Phytochemical characteristics of the decoction extracts were also investigated by thin layer chromatography (TLC). The leaf decoction extract of AT significantly exhibited the highest in vitro antiox...

In this work, lipid extracts from spinach membrane fragments enriched in Photosystem II (PSII) and from spinach PSII dimers were analyzed, by means of Thin Layer Chromatography (TLC) and Electro-Spray Ionization Mass Spectrometry. Cardiolipin found in association with PSII was isolated and purified by preparative TLC, then characterized by mass and mass-mass analyses. Cardiolipin structures wit...

A tadalafil analogue was detected in a dietary supplement marketed for tonic effect, along with hydroxyhomosildenafil and aminotadalafil. The tadalafil analogue was isolated by preparative thin layer chromatography (TLC) and its structure was elucidated using high-performance liquid chromatography (HPLC), liquid chromatography electrospray ionization-mass spectrometry (LC-ESI-MS), Fourier trans...

Barleria cristata Linn is an ornamental plant that grows on the sides of roads in India, China, and other countries. This belongs to family Acanthaceae. In it used as herbal medicine called Kala Bansa. It has ancient legacy application folk medicine, particularly for treatment tuberculosis snake bites. The purpose present study was a preliminary phytochemical analysis, Thin-Layer Chromatography...

Chromatography is a separation technique used to isolate a pure compound from a mixture using the difference in polar...

Production of lysine by Corynebacterium glutamicum (PTCC 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. For this purpose, ammonium sulphate was selected as a constant nitrogen source. The effect of different nitrogen sources was also investigated with glucose as a constant carbon source. The production of L-lysine was exam...

Equol, a metabolite of daidzein for some intestinal microflora, is known to retain highly estrogenic activity and is of wide interest in relation to human health. However, not all humans can produce equol. In this study, detection of urinary equol using thin-layer chromatography (TLC) was performed to distinguish between equol producers and non-producers. After 36 h of soy food intake, urine, c...
