[Study on the inclusion of oridonin-beta-cyclodextrin]

The inclusion compound of Oridonin-beta-cyclodextrin was prepared by the liquid-phase method in aqueous solution. And it was confirmed by thin layer chromatography, differential thermal analysis and specific rotation. The change (A) of ultraviolet spectrum was determined. The composition ratio of inclusion compound between Oridonin and beta-CD was obtained by the continuous variation method.
