A randomized, double-blind, placebo-controlled trial of oral procyanidin with vitamins A, C, E for melasma among Filipino women.

30 Jul 2009 BACKGROUND: Melasma is a common, acquired, symmetric hypermelanosis characterized by irregular brown to gray-brown macules on the cheeks, forehead, nasal bridge, cutaneous part of the upper lip, mandible, and the upper arms. Few trials have been ... Read more...

Increase of theaflavin gallates and thearubigins by acceleration of catechin oxidation in a new fermented tea product obtained by the tea-rolling processing of loquat ( Eriobotrya japonica ) and green tea leaves.

6 Jul 2009 In a project to produce a new fermented tea product from non-used tea leaves harvested in the summer, we found that kneading tea leaves ( Camellia sinensis ) with fresh loquat leaves ( Eriobotrya japonica ) accelerated the enzymatic oxidation of tea ... Read more...

Inhibition of P-glycoprotein function by procyanidine on blood-brain barrier.

29 Jun 2009 The inhibitory effects of procyanidine, one of the components from the bark of Pinus massoniana Lamb, on the P-glycoprotein (P-gp) function of the blood-brain barrier (BBB) were studied using in vitro rat brain microvessel endothelial cells (RBMECs) ... Read more...
