Abstract

|
Various lines of evidence suggest that dietary components protect the initiation of carcinogenesis. In this study, the ethanol extracts (AGE) and the methanol and hexane partition layers (AGEM, AGEH) of the Angelica radix were screened for their cytotoxic effects using the MTT assay on HepG2, HeLa, MCF7 and SW626 cells and for their ability to induce quinone reductase (QR) in HepG2 cells. AGEM and AGEH of the Angelica radix showed the strongest cytotoxic effects on HepG2 and HeLa cells. Cell growth was inhibited by 99.8% and 99.8% on HepG2 cells and 99.3% and 99.4% on HeLa cells, at dose of 100 μg/ mL of AGEM and AGEH extracts respectively. AGE and AGEH significantly induced QR activities in the HepG2 cells. The QR activities of HepG2 cells grown in the presence of AGE, AGEH, and AGEM at the concentration of 50 μg/mL were 313.5, 273.3 and 133.3 nmol/min/mg protein, respectively. Therefore, based on these studies, Angelica radix may be developed into a potentially useful cancer chemopreventive agent.
