Abstract:
Objective To establish a method to simultaneously determine syringing and isofraxidin by HPLC;To investigate the features of percutaneous absorption in vitro of Jiegugao blended and pasted by white vinegar, honey and vaseline; To discuss the mechanism of commonly used ointment matrices in Tujia Minority. Methods Rat abdomen skin in vitro was as transdermal barrier;the modified Franz diffusion pool was used to simulate human skin medication; the content of syringin and isoprofen was determined by HPLC; the percutaneous absorption equation was established and the related parameters, such as cumulative permeation rate and permeation rate, were calculated. Results When using Syncronis C18 (250 mm × 4.6 mm, 5 μm) as chromatographic column, acetonitrile-0.1%phosphoric acid as mobile phase, 1.0 mL/min as perfusion speed and 265 nm as determine wavelength, regression equation of syringingwas A=10 686.454 6C+1565.778 8 (r=1.000 0), regression equation of isofraxidin was A=12 297.305 4C-5913.729 9 (r=0.999 9). Cumulative permeation quantity of syringing in Jiegugao blended and pasted by white vinegar, honey, vaseline and blank were 7.549 2, 4.580 3, 3.890 8 and 5.378 4 μg?cm-2?h-1 respectively and permeation rate were 25.66%, 16.11%, 13.73% and 18.78%. Meanwhile, cumulative permeation quantity of isofraxidin were 2.536 9, 1.941 8, 1.178 2 and 2.293 6 μg?cm-2?h-1 respectively and permeation rate were 47.04%, 35.06%, 22.11%and 41.11%. Conclusion Using white vinegar as the ointment matrix can promote the percutaneous absorption of effective composition in Jiegugao blended. However, it will retard the percutaneous absorption of effective composition in Jiegugao when using honey and vaseline as the ointment matrices, but honey and vaseline can be used as a slow-release matrix.
