[Study on anti-cancer components of Fig residues with supper critical fluid CO2 extracting technique].

ABSTRACT

OBJECTIVE: To optimize Supper Critical CO2 extracting technical (SFE-CO2) methods for extraction of anti-cancer active components of Fig Residues and to investigate the anti-cancer effect of the extract in vitro and in vivo. METHOD: The anti-cancer activity of extracted compound was measured on U937,95D and AGS cancer cells in vitro by MTT method. The anti-cancer effect of the extraction of Fig Residues was studied on mice transplant liver cancer in vivo. RESULT: The SFE-CO2 condition for extraction of the anti-cancer components of Fig Residues was optimized as follows granularity was 100, the extraction pressure was 30 MPa, the extraction temperature was 45 degrees C, the extraction time was 6 h and the CO2 flux was 12 L x h(-1); The IC50 of anti-cancer active components of Fig Residues on U937, 95D and AGS cells were 70.125 microg x mL(-1), 127.957 microg x mL(-1), 116.000 microg x mL(-1); The anti-cancer active components of Fig Residues inhibited 49.3% of the transplanted liver cancer in the mice. CONCLUSION: The method for extracting the anticancer active components of Fig Residues is stable and reasonable, and the extract from Fig Residues is of the anticancer effect.
