Cardenolides, as a group of natural products that can bind to Na+/K+-ATPase with an inhibiting activity, are traditionally used to treat congestive heart failure. Recent studies have demonstrated that the strong tumor cytotoxicities of cardenolides are mainly due to inducing the tumor cells apoptosis through different expression and cellular location of Na+/K+-ATPase α-subunits. The leaves, flesh,...
The aim of this study was to improve the dissolution rate and oral bioavailability of Ginkgo biloba extract (GBE) through the preparation of G. biloba extract solid dispersions (GBE-SD) via hot-melt extrusion (HME). First, we prepared the GBE-SD based on a Kollidon® VA64/Kolliphor® RH40 (85:15) spray dried powder. Then physicochemical properties were investigated by differential scanning calorimetry...
