STUDYINGTHE EFFECTS OF PRELIMINARY TREATMENTS AND DRYING MEASURES ON THE QUALITY AND VOLUME OF STEMONA TUBEROSALOUR.

Abstract

Two experiments were conducted to determine the effects of preliminary processing and drying methods on the quality and volume of medicinal herbs belonging to the Stemona tuberosa Lour. Preliminary processing experiments were conducted with 2 formulae for whole roots and sliced roots, 4 different drying formulae by sun drying, convection drying at temperatures of 50⁰C, 55⁰C, and 60⁰C, respectively. Research results show that: When sliced, the color and content of active ingredients are higher than those of the whole root; drying formula at 60⁰C brings about the best content of active ingredients and organoleptic quality.
