title: [Preparation technology and dissolution research of Blumea volatile oil suppository].
abstract: OBJECTIVE
  To research the preparation technology and dissolution of Blumea volatile oil suppository.
  
  
  METHODS
  In order to establish the content determination and methodology inspection method of Blumea volatile oil plug, the extraction process of Blumea volatile oil was optimized by using orthogonal test. Optimization on the investigation to the suppository matrix by melting time, appearance and dissolution was carried on. The best prescription craft was determined by determining the best molding temperature, dosage of the matrix and complementary makings. The determination method of dissolution was established by investigating different dissolution method and its impact on the preparation of dissolution.
  
  
  RESULTS
  The best conditions of steam distillation extracted Blumea volatile oil was as followed, the ratio of gardenia to liquor 1:6, 2.5% drug amount of sodium, 8 hours of extracting time. The optimum temperature for mold was 60-65 degrees C. Preparation technique of Blumea volatile oil suppository was stable, which after 45 minutes and 3 h in pH 4.5 PBS released at least 70% and 90%.
  
  
  CONCLUSIONS
  Blumea volatile oil suppository with rational prescription, simple preparation and good stability.
