To probe the optimal technol. of preparation technique of zedoary turmeric oil and borneol soft capsule.Studied the preparation technique systematically by screening, including the shell composition of the soft capsule, the diluent of contents, the proportion of zedoary turmeric oil and borneol and diluent, and the drying of the soft capsule.The optimal preparation technique of zedoary turmeric oil and borneol soft capsule were: heating 400 mL polyethylene glycol to 80°, putting into borneol, after it was dissolved completely adding 4000 mL polyethylene glycol and stirring to dissolution, when the temperature of it dropped to 40-50°, putting into zedoary turmeric oil and stirring to make even, after the temperature dropped to 25-30°, processing by colloid mill, the output being the content of the soft capsule, filling the soft capsule with it and sealing under the constant temperature, and drying the soft capsule for 6 h in the condition of 35° and 30% relative humidity.The technique for preparation of zedoary turmeric oil and borneol soft capsule is stable and feasible.
