Abstract:
To optimize the solvent system of high-speed counter-current chromatography (HSCCC) for diterpenoidtanshinone separation and define it's antitumor activity in vitro. Total diterpenoidtanshinone was made by CO2 supercritical fluid extraction (SFE), UPLC was applied to determining the peak area of tanshinone IIA and cryptotanshinone in different solvents up or under phase, and the partition coefficient K values of them were calculated. CKK-8 was used to observe the inhibitory effects of diterpenoidtanshinone on human liver cancer (QGY-7703), lung cancer (PC9, A549), gastric cancer (MKN-45, HGC-27), colon cancer (HCT116), myeloma (U266, RPMI8226), and breast cancer (MCF-7). The best solvent system for HSCCC was petroleum ether-ethyl acetate-methanol-aqua (12∶8∶ 13∶7). The yield of diterpenoidtanshinone was 8.65%. Diterpenoidtanshinone has good effect of antitumor in vitro especially on human PC9 cell. The selected solvent system is suitable for diterpenoidtanshinone separation by HSCCC, and the established HSCCC method is reliable and easy for operating. Diterpenoidtanshinone has good antitumor effect in vitro.
