Sipyukmiryuki-eum (SYMYKE), Danjacheongpi-tang (DJCPT), Jipae-san Ⅰ (JPS Ⅰ), Jipae-san Ⅱ (JPS Ⅱ), and Chungganhaeul-tang (CGHUT) are representative herb-combined remedies used in traditional Korean medicine for treating breast cancer patients, as mentioned in "Dongeuibogam." In this study, we investigated the total phenolic contents (TPCs) and the anti-oxidant and anti-microbial activities of hot water and 70% ethanol extracts of these herbal prescriptions. Among the five herb-combined remedies, the extraction yields of the hot water extracts and 70% ethanol extracts were the highest in JPS Ⅱ (34.30%) and DJCPT (30.50%), respectively. The TPCs of the hot water extracts from the herb medicines were rich in the order of JPS Ⅰ < CGHUT < JPS Ⅱ < SYMYKE < DJCPT. In addition, the 70% ethanol extracts from the herb medicines were rich in the order of JPS Ⅱ < JPS Ⅰ < CGHUT < SYMYKE < DJCPT. Among them, DJCPT and SYMYKE displayed a strong anti-oxidant capability, which was determined using ferric-reducing anti-oxidant power and scavenging of 2,2'-diphenyl-1-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical activity assays. In addition, anti-microbial activities against Staphylococcus aureus and Escherichia coli were stronger in the 70% ethanol extracts than in the hot water extracts. Together, these findings reveal a positive relationship between TPCs and their anti-oxidant activities.
