In recent years, increasing knowledge of the positive health effects of food polyphenols has
prompted the need to develop new separation techniques for their extraction, fractionation …

Microemulsions are potentially excellent carriers for bioactive molecules. They offer the
advantage of spontaneous formation, ease of manufacture, thermodynamic stability, and …

Extracts of leaves from the tea plant Camellia sinensis contain polyphenolic components
with activity against a wide spectrum of microbes. Studies conducted over the last 20 years …

The past decade has seen considerable interest and progress in unraveling the beneficial
health effects of tea, particularly its polyphenolic components and its antioxidant activity …

The present study was aimed to develop a catechin (CA) loaded nanoemulsion based nano-
gel for the protection of skin against ultraviolet radiation (UV) induced photo-damage and to …

An ultra-high performance liquid chromatography (UHPLC) with UV detection method was
developed for the fast quantitation of the most represented and biologically important green …

We describe the use of titanium dioxide nanoparticles (TiO2 NPs) as selective probes and
matrices for the determination of catechins using surface‐assisted laser …

Epigallocatechin gallate is the major component of the polyphenolic fraction of green tea
and is responsible for most of the therapeutic benefits of green tea consumption. A number …

A micellar electrokinetic chromatography (MEKC) method was developed for the
quantitation of polyphenols (+)-catechin and (−)-epicatechin (catechin monomers) and the …

Compared to MEKC, the presence of a water‐immiscible oil phase in the microemulsion
droplets of microemulsion EKC (MEEKC) gives rise to some special properties, such as …
