신선초와 신선초박에 배양한 노루궁뎅이버섯 균사체 에탄올 추출물의 생리활성 효과

Abstract

The purpose of this study was to investigate the antioxidant, nitrite scavenging, angiotensin-converting enzyme (ACE), and tyrosinase inhibition activities of ethanol extracts from Hericium erinaceus (HE) cultured in Angelica keiskei (AK) and Angelica keiskei pomace (AKP). Antioxidant activities of the HE, AK, AKP, HE+AK, and HE+AKP extracts were higher than that of control, but lower than those of BHT and Vit C. Tyrosinase inhibition activity was the highest in AKP+HE extract (90%), whereas those of HE, AK, AKP, and AK+HE extracts were about 57, 61, 82, and 78%, respectively. Nitrite scavenging abilities of various samples were above 80% at pH 1.2, and there was no significant difference between the HE, AK, AK+HE, and AKP+HE extracts at pH 3.0, excepting the AKP extract. ACE inhibition activity was the highest in AKP extract (60%), whereas those of HE, AK, AK+HE and AKP+HE extracts were about 42%, 50%, 35% and 40%, respectively. These results suggest that H. erinaceus cultured in AK and AKP may be used as a raw material for functional foods, and food additives, as well as in the cosmetic industry as a natural source of bioactive compound after further investigation in vivo.
