Antioxidative effect of rhizome of Zinziber officinale on paraben induced lipid peroxidation: an in vitro study.

Antioxidative effect of aqueous extract of rhizome of Ginger (Zinziber officinale) was examined on p-hydroxybenzoic acid (paraben) induced lipid peroxidation. Addition of paraben (25-150 microg/mL) to liver and kidney homogenates significantly increases H2O2 induced lipid peroxidation in vitro. Effect was dose dependent up to 100 microg/mL concentration. An addition of aqueous extract of ginger significantly reduced paraben (100 microg/mL) induced lipid peroxidation in liver and kidney homogenates. The effect was concentration dependent.
