Characterization and antioxidant activity of dihydromyricetin–lecithin complex

Characterization and DPPH Radical Scavenging Activity of Gallic Acid-Lecithin Complex

“…It seems that gallic acid had become completely dispersed in lecithin by some weak interactions. A similar observation of guest molecule losing its characteristic DSC peaks has also previously been reported for the complexation of dihydromyricetin with lecithin [4]. Powder x-ray diffractometry has been shown to be a method which can provide insight into the complexation between host and guest molecules.…”

“…The low hydrophobicity of gallic acid can result in its poor permeation across the intestinal epithelial cells and minimize gastrointestinal tract absorption, leading to decreased oral bioavailability. Lecithin is a group of yellow-brownish fatty substances occurring in animal and plant tissues, and in egg yolk [4], which can be used as a matrix to improve lipophilic property and targeted delivery of bioactive compounds [5,6]. It is expected that gallic acid combined with lecithin might result in the improvement of lipophilic property of gallic acid.…”

Physiochemical properties of the complex of myricetin and hydroxypropyl-β-cyclodextrin

“…According to an earlier report [6], it was found that dihydromyricetin was completely dispersed in lecithin and that there were some interactions, possibly a combination of hydrogen bonds and van der Waals force.…”

Physicochemical Properties and Lipophilicity of Polydatin-Lecithin Complex

“…Lecithin is a group of yellow-brownish fatty substances occurring in animal and plant tissues, and in egg yolk [4], which can be used as a matrix to improve lipophilic property and targeted delivery of bioactive compounds [5,6]. Some researches indicated that the natural active constituents combined with lecithin might improvement the lipophilic property and the oral bioavailability of the natural active constituent, under certain conditions [7].…”
