ABSTRACT
<p><b>OBJECTIVE</b>To study optimal process conditions for the inclusion of volatile oil from Nardostachyos Radix et Rhizoma using saturated water solution method.</p><p><b>METHOD</b>The optimal technology of inclusion was identified respectively by the utilization ratio of volatile oils and the yield of inclusion compound in an orthogonal experiment design, and the inclusion efficiency was evaluated by TLC, UV, IR, SE and GC-MS.</p><p><b>RESULT</b>The optimum preparation conditions for inclusion were established as follows volatile oil beta-CD was 1 6, the inclusion temperature was 40 degrees C, the stirring speed and time were in 300 r x min(-1) and for 1 h. The analysis results showed that a new substance was conformed. The change of the volatile oil component was found before and after inclusion.</p><p><b>CONCLUSION</b>The optimal process conditions are easy for operation, and high in utilization ratio of volatile oils and the yield of inclusion compound.</p>
