Abstract:
AIM To prepare nanostructured lipid carriers for volatile oils from Artemisiae argyi Folium.METHODS Heated melting-ultrasonic dispersion method was applied to preparing lipid carriers.Taking solid/liquid lipid ratio,amounts of lipid,emulsifier and volatile oils as influencing factors,and average paticle size as an evaluation index,the formulation was optimized by orthogonal test.With cineole,camphor and borneol as indices,GC-MS was adopted in the content determination of volatile oils.RESULTS The optimal formulation was determined to be 5 ∶ 5 for solid/liquid lipid ratio,1%,3% and 0.5% for amounts of lipid,emulsifier and volatile oils,respectively.The obtained clear and transparent lipid carriers demonstrated the average particle size of (72.33 ±1.93) nm,PDI of 0.273 ± 0.004 5,and Zeta potential of (-30.59 ± 1.42) mV,whose in vitro release rate was lower than that of raw medicine within 120 h,along with a higher stability under 4 ℃ than that under 25 ℃.The entrapment efficiencies of cineole,camphor and borneol were 87.49%,86.45% and 92.12% with the drug loadings of 8.25%,2.00% and 3.38%,respectively.CONCLUSION It is suggested that nanostructured lipid carriers for volatile oils from Artemisiae argyi Folium should be stored under 4 ℃ with the features of sustainedrelease and stable physicochemical properties.
