Study on Inclusion Technology for Volatile Oil of Pogostemon Cablin / 中国中医药信息杂志

ABSTRACT

Objective To optimize extraction technology for volatile oil of Pogostemon cablin in the second traditional veterinary drugs anti-stress granule.Methods The single factor was used to investigate the concentration and amount of the ethanol before inclusion of volatile oil.The L9(34) orthogonal design was used to optimize the factors in the process of inclusion.Results The optimal of technology method was that volatile oil was dissolved with 95% EtOH by 120(mL/mL),the ratio of oil and ?-CD was 18,?-CD was prepared the concentration of 10%,ultrasound pool was at 40 ℃,2.0 h.Conclusion The optimized process is stable and adjustable quality.
