This study was conducted to investigate the physiological functionality of the hot water and 70% acetone extracts obtained from the pine needle and mugwort. Flavanol tannin content was above 60% of the total polyphenol in pine needle extracts. 70% Acetone extract from pine needle exhibited inhibition percentage of about 82.2% on the mutagenicity of Trp-P-1. Angiotensin I converting enzyme(ACE) inhibition activity was 61% and 50% in the hot water extract and in the 70% acetone extract respectively. Electron donating ability(EDA) of the hot water and 70% acetone extracts obtained from the pine needle was significantly good above 80%. 70% Acetone extract from pine needle showed inhibitary effect against the polyphenol oxidase(PPO) of water dropwort. The nitrite scavenging ability was appeared in all the extracts examined and it showed $80{\sim}90%$ at pH 3.0. The oxidative stability was determined by POV. Results showed that ethyl acetate fraction is better antioxidants than chloroform and butanol fractions in the soybean oil. Then, in the mugwort extracts, antimutagenicity of 70% acetone extract was similar to that of pine needle. Ratio of ACE inhibition activity was higher than that of pine needle extracts. EDA of hot water and 70% acetone extracts was 45%. Extracts from the mugwort were lower in nitrite scavenging ability about $20{\sim}30%$ than extracts from pine needle.
