OBJECTIVE:To optimize the preparation technology of Oleum Baeckeae oil - ?-cyclodextrin inclusion complex. METHODS:The preparation technology for Oleum Baeckeae oil-?-cyclodextrin inclusion complex was optimized by orthogonal experiment taking the ratio of the Oleum Baeckeaee oil to ?-cyclodextrin, the temperature for clathration and the duration of stirring as three factors and with the utilization ratio of the essential oil in Oleum Baeckeae oil inclusion complex as index. RESULTS:The optimal technological condition was as follows:the ratio of the Oleum Baeckeae oil to ?-cyclodextrin in the inclusion complex was 1∶10; the temperature for clathration was 50℃, and the duration of stirring was 2 hours. Under this condition, the average utilization ratio of Oleum Baeckeae oil was as high as 81.90%. CONCLUSION:The optimized preparation technology of Oleum Baeckeae oil - ?-cyclodextrin inclusion complex is feasible and serves as reference for the enhancing of stability of Oleum Baeckeae oil preparation.

OBJECTIVE:To provide reference for chemical composition analysis in Angiopteris fokiensis. METHODS:The fat-soluble components in A. fokiensis were extracted and separated. The separated fat-soluble compounds were analyzed and identi-fied by GC-MS after methyl esterification. RESULTS & CONCLUSIONS:Totally 52 compounds were detected and 43 of those were identified. They were mainly organic acids and sterols compounds. The 43 components are first identified in A. fokiensis.
