Abstract

The anticancer effect of methanol extracts from common Chinese cabbage kimchi(CC kimchi ) and organically cultivated Chinese cabbage kimchi (OC kimchi) was studied on the cell growth, MTT assay and SRB assay using AGS human gastric cancer cells. Methanol extracts from CC kimchi and OC kimchi exhibited the anticancer activites in vitro and in vivo. Methanol extract from 6 day-fermented CC kimchi and OC kimchi inhibited the growth of AGS cells by 55.2 and 60.7% , respectively. At MTT assay an dSRB assay, 6 day-fermented OC kimchi showed higher inhibition rate (MTT : 42%, SRB : 61%) than 6 day-fermented CC kimchi(MTT : 33%, SRB : 52%). Methanol extracts from 6-day fermented CC kimchi and OC reduced the tumor formation and prolonged the life span of sarcoma-180 cell injected Balb.c mouse. OC kimchi treated group resulted in the smaller tumor weight of 4.58$\pm$0.32g compared th the CC kimchi group of 5.40$\pm$0.78g and the control group of 7.50$\pm$0.54g and OC kimchi treted group (25.3 days) lived longest among control (20.2days ) and CC kimchi(23.5days) treted groups.
