Abstract: To study effect of extracts from bark of Juglans mandshurica (EMBJM) on proliferation and cell cycle of SMMC-7721 cells, the SMMC-7721 cells in culture medium in vitro were given different concentrations of EMBJM. The inhibition rate of EMBJM on the SMMC-7721 cell was detected by MTT assay. The cell cycle analyzed was detected by flow cytometry (FCM). The EMBJM exhibited a significant inhibition on SMMC-7721 cells time-and dose-dependently. The cell cycle detection results suggested that EMBJM could arrest SMMC-7721 cells specifically in growth 2/mitosis(G2/M) and synthesis(S) phase cell cycle in a dose-dependent manner. Compared with control group (8.34%±1.42%; 26.80%±1.76%), the G2/M and S phase of SMMC-7721 cells exposed to EMBJM (13.89%±2.46%, 39.87%±2.83% (8 mg/L);(14.35%±2.68%, 44.81%±2.93% (16 mg/L)) were significantly increased (P<0.05, n=3). EMBJM can effectively inhibited proliferation in SMMC-7721 cells and effected cell cycle distribution.
