PROCEDURE
实验过程
Codeine laurate and hydroxypropyl-beta-cyclodextrin were complexed by the kneading method. Codeine laurate (0.700 g) and hydroxypropyl-beta-cyclodextrin (2.045 g) were blended together. Water (5 ml was added and the mixture ground together in a mortar with a pestle to form a uniform paste. Grinding was continued for 30 minutes. The paste was then dried in a vacuum oven (40° C.; 0 bar) for 48 hours. The solid mass was broken up, passed through a 60 mesh screen and returned to the vacuum oven (40° C.; 0 bar) for 12 hours in order to ensure uniform drying of the complex. Analysis by HPLC for codeine base content, and Karl Fisher for moisture content gave the following results: % codeine base was 14.49%, and the moisture contents was 4.21%. The complex was characterised by DSC, FT-IR and XRD.
