[Influence of different technique process and prescription on dampproof performance of pharmaceutical materials of traditional Chinese medicine].

OBJECTIVE: To study the influence of different technique process and prescription on hygroscopic property of pharmaceutical materials of traditional Chinese medecine (TCM) was studied.

METHOD: The sample prepared with banlangen and different excipients had been put in certain suroundings for 24 hours, then the hygroscopic curves and their parameters of hydroscopicity were gotten; the influence of that on hygscopic property of banlangen was studied.

RESULT: The optimized damp-proof materials was polyoxylate II. The damp-proof effect enhanced with the increase of temperature and the excipient the decrease of and concentration of ethanol.

CONCLUSION: Excipients have different effect on hyproscopic property of banlangen, and the damp-proof technology has direct effect on it.
