Molecular identification and phytochemical profiling of kamiling (wild toxic plant) using thin layer chromatography

International Journal of Secondary Metabolite, 2018
Some plants may only be known by the people in their own respective place. Consequently, there is a need for the authentication and further study of wild toxic plant known by indigenous people.

Pharmaceutical Applications of TLC

, 2001
This article summarizes the application of thin-layer chromatography (TLC) to the separation (analysis) of pharmaceuticals. The vast majority of applied methods involve classic TLC; however, both forced-flow TLC and planar electrophoresis are gaining in ...

TLC-densitometric analysis of α-escin in bulk drug substance and in pharmaceutical dosage forms

Current Issues in Pharmacy and Medical Sciences, 2015
A quite simple and rapid TLC-densitometric method for the identification of α-escin (Aescin) in bulk drug substances was developed. In so doing, different chromatographic conditions, including various mobile and stationary phases, were tested.

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

Journal of the American Oil Chemists' Society, EarlyView.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Isolation and functional analysis of cDNAs similar to Hyp-1 involved in hypericin biosynthesis from Hypericum erectum

Biologia Plantarum, 2010
Hypericin, a naphthodianthrone, has been identified as the principal active compound found in St. John's wort (Hypericum perforatum L.). To generate a gene resource for hypericin and other valuable metabolites, we generated expressed sequence tags (ESTs)

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,
