Ultrasonic Induced Preparation of the Inclusion Complex of Perilla Frutescens Essential Oil with β-cyclodextrin

摘要

In order to get Perilla frutescens (L.) seed oil (PSO) inclusion compound with β-cyclodextrin (β-CD). The ultrasonic induced preparation parameters was studied. Basis on the signal factor test, an orthogonal experiment L_9(3)~4 was applied to optimize the best preparation conditions. The optimum preparation parameters were determined as follows: ultrasonic power200W, ultrasonic time20min, inclusion temperature 48°C and ratio of PSO to β-CD 1:5 (ml/g). Under optimized conditions, the inclusion ratio was 81.1%. All the results indicated that ultrasonic induced preparation of PSO inclusion compound with β-CD was a suitable method for it has shorter time and higher inclusion ratio.
