OBJECTIVE
To study on volatice oil from Atractylodes macrosephala Koidz with different distill methods and find the better method.
METHODS
GC-MS was used to analyze the chemical constituents of volatice oil from Atractylodes macrocephala Koidz with different distill methods.
RESULTS
The extraction rates of volatice oil with steam distillation was 1.01%, the components of the oil were examined by GC-MS, 15 of the 18 were identified. The extraction rates of volatice oil with ultrasonic wave was 1.60%, the components examined, 20 of the 24 were identified. The extraction rates of volatice oil with SFE-CO2 was 2.32%, the components examined, 37 of the 49 were identified. Atractylon was the highest one. There were 12 common components in the identified ones.
CONCLUSIONS
The components of volatice oil from Atractylodes macrocephala Koidz with different distill methods have difference but similarities, it can provide a method for Atractylodes macrocephala Koidz's quality control. The extraction rates is higher and the components are more with the method of SFE-CO2.
