Preparation and Physico-chemical Characterization of EGCG-phospholipid Complex

doi:10.7506/spkx1002-6630-201313020

Abstract

Abstract:

In this study, EGCG-phospholipid complex was prepared through the dissolution of EGCG and soybean
lecithin in ethanol, and its structure was characterized by UV spectroscopy, IR spectroscopy, X-ray powder diffractometry
and differential scanning calorimetry. Meanwhile, the apparent water/n-octanol partition coefficient of this complex was
determined. The results showed that non-covalent bonding between EGCG and phospholipid under experimental conditions
generated the target complex. Furthermore, the solubility of EGCG was improved according to apparent partition coefficients
of EGCG and EGCG-phospholipid complex in n-octanol buffer solution system.

Key words: EGCG, EGCG-phospholipid complex, spectral analysis, X-ray power diffractometry (X-RPD), differential scanning calorimetry (DSC)
