PROCESS FOR PULVERIZING OF PROPOLIS AND MEDICINAL PLANT-EXTRACTS AND FOR THE DRY EXTRACTION OF AGENTS OF PROPOLIS

摘要

Solid dispersions contg. high concns. of active matter derived from propolis and medicinal herbs, are prepd. by treating their extracts or solns. (obtd. by customary means) with colloidal silica. - Alternatively a solid dispersion is prepd. by dry extn. when raw propolis is treated at required temps. with silica, either on its own, or in the presence of small quantities of a solubilising agent
