Abstract:
OBJECTIVETo study the toxicity on skin and penetration effect of volatile oil from tender branchers of Camellia oleifera on nitrendipine, baicalin, nimesulide for percutaneous obsorption.
METHODAcute skin toxicity, irritation and allergy on rats were tested, and mouse skin in vitro was applied for studying the effects of different concentrations of volatile oil in nitrendipine, baicalin, nimesulide on drug permeation.
RESULTDifferent dosage volatile oil had no acute toxicity, irritation or hypersensitive effects. Compared to azone, more powerful enhancement effects of volatile oil at different concentration on nitrendipine, baicalin, nimesulide were very obvious.
CONCLUSIONThis paper firstly reported the results of experiment about the toxicity to skin and penetr-ation effect of volatile oil from tender branches of C. oleifera.
