Study on preparation of ?-cyclodextrin inclusion compound of volatile oil from Fructus Amomi Rotundus / 中成药

Objective: To study optimum inclusion process conditions for volatile oil from Fructus Amomi Rotunds. Methods: The study was carried out with orthogonal design. The process conditions were studied by determining the utilazision ratio of volatile oil from Fructus Amomi Rotundus. Results: The optimum preparation conditions for inclusion were established as: volatile oil:? CD was 1∶8, The inclusion temperature was at 50 ?C and inclusion time for 2h, The ultilizasion ratio of volatile oil was 79.7%. Conclusion: The method can be used for mass production.
