Abstract
Hepatocarcinoma, a malignant cancer, threaten human life badly. It is a current issue to seek the effective natural remedy from plant to treat cancer due to the resistance of the advanced hepatocarcinoma to chemotherapy. Puerarin (Pue), a major active ingredient in the traditional Chinese medicine Gegen, has a wide range of pharmacological properties and is considered to have anti-hepatocarcinoma effects. However its low oral bioavailability restricts its wide application. In this report, Pue nanosuspension (Pue-NS) composed of Pue and poloxamer 188 was prepared by high pressure homogenization technique. The in vitro anti-hepatocarcinoma effects of Pue-NS relative to efficacy of bulk Pue were evaluated. The particle size and zeta potential of Pue-NS were 218.5 nm and −18.8 mV, respectively. MTT assay showed that Pue-NS effectively inhibited the proliferation of HepG2 cells, and the corresponding IC50 values of Pue-NS and bulk Pue were 3.39 and 5.73 μg/ml. These results suggest that the delivery of Pue-NS is a promising approach for treating tumors.
