title: [Lycopene liposomes: lycopene release in vitro and pharmaceutical behaviors and antioxidation in vivo].
abstract: Lycopene liposomes were prepared by conventional rotary-evaporated film-ultrasonication method. The release of lycopene from lycopene liposome was evaluated in vitro. The pharmacokinetic parameters of lycopene liposomes (L-LYC) and lycopene (LYC) oil, the effect of LYC and L-LYC on antioxidation were also investigated in rats. HPLC method was used to assay the concentration of lycopene in rat's plasma. Pharmacokinetic parameters were estimated by 3P97 program. The release of L-LYC and LYC were measured in the artificial stomach liquid and bowel liquid. After 4 weeks of L-LYC or LYC feeding, the activity of SOD, T-AOC, GSH-Px, MDA and CAT in serum and liver were measured separately. The pharmacokinetic parameters of LYC oil and L-LYC in a single dose were 4.45 and 7.45 h for Tmax; 0.473 and 0.654 microg x mL(-1) for Cmax; 12.38 and 21.67 mirog x h x mL(-1) for AUC,respectively. The activities of GSH-Px and T-AOC in serum and liver of the L-LYC group increased (P < 0.05) and the concentrations of MDA and CAT decreased significantly (P < 0.05). It could be concluded that lycopene liposomes could prolong the time of absorption. L-LYC could increase antioxidative effect and reduce lipid peroxidation obviously compared with LYC in rats.
