Study on permeability of horse fat.

【Objective】To investigate the permeability in vitro of horse fat.【Method】Detecting wavelength of horse fat,sheep fat,pig fat and peanut oil were confirmed by UV spectrophotometer,where the standard curves were prepared.Using sprague-dawlay skin as permeable membranes,the permeation quantity and permeation rate of horse fat,sheep fat,pig fat and peanut oil were studied.The permeating equation of different fat was built.【Result】The permeation quantity(μL/cm2) of horse fat is bigger than sheep fat,pig fat and peanut oil during the 2-10 hours of permeating,the order of the permeation quantity is horse fatpeanut oil≈sheep fatpig fat.The permeation rate(μL/cm2·h)were 2.132 1,1.247 9,0.736 0,1.276 4 respectively.【Conclusion】The permeation rate of horse fat is stronger than sheep fat,pig fat and peanut oil.
