                 Abstract: Total volatile oil from the branches and leaves of Podocarpus macrophyllus was extracted by the
                 combination  of microcapsule technology and aqueous two-phase extraction  technology.  After  screening,
                 -cyclodextrin and sodium sulfate was selected as extraction agents in aqueous two-phase system. On the
                 basis of single factor experiment, the extraction conditions for volatile oil from Podocarpus macrophyllus
                 were  optimized  by  four-factor  and  three-level  response  surface  methodology.  The  optimum  extraction
                 conditions were obtained as follows: extraction time 36 min, mass fraction of -cyclodextrin 42%, mass
                 fraction of sodium sulfate 15%, and extraction temperature 33 ℃. Under these conditions, the yield of total
                 volatile  oil  from  Podocarpus macrophyllus  was  1.369%.  A  total  of  22  compounds  were  identified  by
                 GC-MS, among which, containing 18 kinds of terpenes and their oxygen-containing derivatives and 4 kinds
                 of  aliphatic  compounds.  The  main  components  of  total  volatile  oil  were  caryophyllene,  α-pinene  and
                 -pinene.
