Abstract: BACKGROUND AND AIM: To investigate the effect of cortex periplocae extract (CPE) on the differentiation of tumor cells K562 in vitro. MATERIALS AND METHODS: We examined the morphological changes of K562 cells after cultured with CPE; and investigated the induction effect of CPE on the production of Hb from K562 cells by using colorimetry. RESULTS: K562 cells morphology were destroyed by CPE. CPE also markedly reduced the production of Hb from K562 cells. CONCLUSION: CPE could kill K562 cells to some extent, but could not induce the differentiation of K562 cells.

Key words: cortex periplocae, K562, kill, differentiation
