title: [Study on solidifying volatile oil of cinnamon with colloidal silicon dioxide SYLOID244FP].
abstract: OBJECTIVE
  To evaluate the properties of solidifying volatile oil of cinnamon with colloidal silicon dioxide SYLOID244FP.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Solidifying herbal volatile oil with SYLOID244FP deserves studying further.
