Outline
To study the preparation of Danggui（Angelicae Sinensis Radix）oilmicrocapsules，screening out the best preparation process and quality evaluation.
The microcapsules of volatile oil from Danggui（Angelicae Sinensis Radix）were prepared by complex coacervation method with gelatin and gum arabic solution as the materials. Tts quality evaluation was carried out through the appearance，microscopy，electronmicroscopy，particle size and other aspects.
When the concentration of gelatin solution was 3%，the concentration of arabic gum solution was 1%，the proportion of volatile oil to bladdermaterial was 30%，the pH value of complex coacervation reaction was 4.2，the temperature of bladder formation was 40℃，the stirring speed was 600 r·min-1，adding curing agent（5 mL）and curing for 30 min，the encapsulation efficiency was the highest（85.62%）. The microcapsulesmade by the optimal technology had good quality.
The microcapsules of Danggui（Angelicae Sinensis Radix）oil prepared by the optimal process have uniform particle size，stable process and good entrapment efficiency.
