Study on solidifying volatile oil of cinnamon with colloidal silicon dioxide SYLOID244FP / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the properties of solidifying volatile oil of cinnamon with colloidal silicon dioxide SYLOID244FP.</p><p><b>METHOD</b>Volatile oil of cinnamon was solidified by SYLOID244FP. The amount of SYLOID244FP was optimized with the cinnamaldehyde yield as criteria. Curing powder was characterized by scanning electron microscopy (SEM) and differential scanning calorimetry(DSC). The effects of SYLOID244FP on dissolution in vitro and thermal stability of cinnamaldehyde were studied.</p><p><b>RESULT</b>The optimum solidification ratio of SYLOID244FP to volatile oil of cinnamon was 1 1. Dissolution rate of cinnamaldehyde increasesd and its thermal stability improved after volatile oil of cinnamon was solidified.</p><p><b>CONCLUSION</b>Solidifying herbal volatile oil with SYLOID244FP deserves studying further.</p>
