Study on preparation of borneol-?-cyclodextrin inclusion complexes in Zhnyu Hewei Zhitong Capsules / 中华中医药杂志

ABSTRACT

Objective:To optimize the preparation of borneol-?-cyclodextrin inclusion complexes in Zhuyu Hewei Zhitong Capsules,and to establish the metered method of borneol in inclusion complexes.Methods:Orthogonal design was used and inclusion complex yield and inclusion rate of berneol were used as evaluation index to optimize the best preparation craft. The chromatographic conditions werePEG-20M with 10%,3m??3mm of application concentration was used as stationary liquid phase,FID detector was used at 140℃,betula oil was used as internal standard substance and the sample was dissolved in Colonial spirit by ultrasounding.Results:The best preparation craft werethe weigh ratio of borneol and?-CD was 16,the ratio of?-CD and moisture addition was 110,reaction time was 30min,the temperature was 30℃.A good linearity was obtained when the concentration of borneol was between 0.7146-4.2878mg/ml(r=0.9999),the average recovery was 101.97%,RSD% was 1.77%.Conclusion:Three batches of tests indicated that the preparation of borneol inclusion complexes was stable and feasible. This assay method of borneol was accurate,sensitive and reproducible.
