An experimental study of cmpound Thallus laminaria granules volatile oil-?-cyclodextrin clathrate / 中国海洋药物

ABSTRACT

Objective To study the best preparation technique of compound Thallus laminaria granules volatile oil-?-cyclodextrin clathrate and examine the stability of the elathrate.Methods The orthogonal design method was used to optimize the formulation.The yeild of the volatile oil and the content of the clathrate were used as the test target.Results The best preparation process was as follows:?-cyclodextrin:compound Thallus laminaria=12:1(g?mL~(-1)),at 50～60℃for 2 hours.Making distillation twice while adding water to the first decoction, steaming 1h after boiling;A_2 B_1 was the best extraction scheme.Conclusion The preparation process can be a scheme to obtain the clathrate with high content of effective component,which can be used in the preparation of the clathrate.
