ABSTRACT OBJECTIVE:To optimize the preparation technology of citronellol submicroemulsion. METHODS:The content of
citronellol in Citronellol submicroemulsion was determined by HPLC. Citronellol submicroemulsion by high-speed shearing
dispersion-high pressure homogenization method, with centrifugation stability constant (ke ) and particle size were used as
evaluation indexes. Its formulation and preparation technology were optimized and validated. Drug-loading amount and
2
encapsulation rate of the preparation were detected. RESULTS:The linear range of citronellol were 4-64 μg/mL(R =0.999 9).
RSDs of precision,stability(24 h)and reproducibility tests were all lower than 3%. The recoveries were 97.64%-101.97%(RSD=
2.28%,n=3),97.71%-99.50%(RSD=1.29%,n=3),96.87%-101.48%(RSD=2.86%,n=3). The optimal formulation included
that total weight of soybean oil and medium chain triglycerides(1 ∶ 1,g/g)was 3.75 g,1.2% soybean phospholipid was 0.6 g,
cholesterol was 0.06 g,citronellol was 1.25 g,0.6 % sodium oleate was 0.3 g,15-hydroxystearic acid polyethylene glycol ester
was 0.75 g,poloxamer 188 was 0.75 g,water added to 50
