ABSTRACT OBJECTIVE:To establish the method for content determination of ligustilide and to optimize the extraction
technology of volatile oil and inclusion technology in Quhan zhufeng granules. METHODS:HPLC method was adopted. The
determination was performed on Waters C18 column with mobile phase consisted of methanol-water(70 ∶ 30,V/V)at the flow rate
of 1 mL/min. The detection wavelength was set at 327 nm,and the column temperature was 30 ℃. The sample size was 10 μL.
Using yield of volatile oil and the content of ligustilide as index,with soaking time,the amount of adding water and extraction
time as factors,the extraction technology was optimized by orthogonal test. Using inclusion rate,the yield of inclusion compound
and yield of volatile oil as index,with ratio of volatile oil to β-cyclodextrin,inclusion temperature and inclusion time as factors,
the inclusion technology of volatile oil was optimized by orthogonal test. RESULTS:The linear range of ligustilide was 0.4-4 μg
(r=0.999 9);RSDs of precision,stability and reproducibility tests were all lower than 2% (n=6). The recoveries were
96.75%-102.03%(RSD=2.06%,n=6). The optimal extraction technology of volatile oil included 10-fold water(mL/g),soaking
for 15 min,extracting for 8 h. Average yield of volatile oil was 0.310 7%,and average content of ligustilide was 0.418 0 mg/g.
The optimal inclusion technology of volatile oil included ratio of β-cyclodextrin and volatile oil was 1 ∶ 8 (mL/g);inclusion
temperature was 50 ℃;inclusion time was 3 h. Average inclusion rate was 69.43%,and the yield of inclusion compound was
58.89%;the yield of volatile oil was 14.15%. CONCLUSIONS:Established determination method is simple,accurate and stable.
The optimal extraction technology of volatile oil and inclusion technology are stable and feasible.
