摘要：

Supercritical CO, extraction of Plumula nelumbinis oil rich in gamma-sitosterol was investigated with a 4(2) full factorial design and response surface analysis. At optimal conditions (P=35 MPa, T=55 degrees C, d(p)=0.22 mm, Q=2.0 L/min), the yield of the extracted oil was up to 12.2%, in which the concentration of gamma-sitosterol was 7.38%, indicating that the gamma-sitosterol contents in Plumula nelumbinis and its oil were much higher than that in other vegetables.
