OBJECTIVE To establish a assay methods for borneol and emodinin in suppositories. METHODS The content of Borneol was determined by GC 15%, polydiethyleneglycol succinate as stationary phase coated on Chromosorb W AW (DMCS) ,column temperature 105℃,inlet temperature250℃; Thin layer scanning was used to determine the content of emodinin. RESULTS The liner range of borneol was 0.283~ 2.262 μg(r= 0.9999) average recovery of 100.5%. The liner range of emodinin was 0.056~ 0.448 μg wit...
