Abstract
Objective : This study was carried out to examine the effect of five fractions of an aqueous extract from Artemisia capillaris $T_{HUNB}$. Methods : The queous extract from Artemisia capillaris $T_{HUNB}$. was fractionized into 5 kinds of material. We observed the effect of each fractions on etoposide-induced apoptosis, cell viability, cell cycle progression and mRNA expression of apoptosis-related genes in human hepatocyte cell line HepG2. Results and Conclusions : The data shows that butanol fraction of Artemisia capillaris $T_{HUNB}$. has no relation with cell cycle, however, it inhibits apoptosis significantly and the action may be due to the suppression of Fas and Sax genes and activation of Bcl-2 gene.
