Biological Activity of Extracts from Cherry Sage (Salvia officinalis L.)

체리 세이지(Salvia officinalis L.) 추출물의 생리활성 탐색

In this study, extracts from S. officinalis were tested for antioxidative effects and inhibitory activities against $\alpha$-amylase, angiotensin converting enzyme (ACE) and xanthine oxidase (XOase). The content of total phenolic compounds in water, 60% ethanol, 60% methanol and 60% acetone extracts were 36.2, 42.7, 40.3 and 39.6 mg/g, respectively. In 60% ethanol extracts, the EDA by DPPH free radical scavenging test of S. officinalis was $66.3{\pm}2.2%$ at $200{\mu}g/ml$. The inhibition rate of ABTS was $97.6{\pm}0.1%$, the antioxidant protection factor was $2.26{\pm}0.63$ PF, and TBARS was $0.62{\pm}0.05$ (${\times}100{\mu}M$ in the control and $0.29{\pm}0.02$ (${\times}100{\mu}M$). Also in 60% ethanol extracts of S. officinalis, the inhibitory activity against XOase was 78% and was not shown to be against ACE. According to the $12.6{\pm}0.14\;mm$ of clear zone formed, the inhibition rate against $\alpha$-Amylase was 7.6% at $200{\mu}g/ml$ of phenolics content. Antimicrobial activities of 60% ethanol extracts of S. officinalis against Helicobacter pylori exhibited an inhibition rate of $12.5{\sim}66.1%$ according to the $10{\sim}15\;mm$ of clear zone at $50{\sim}200{\mu}g/ml$. The results suggest that the 60% ethanol extracts from Salvia officinalis L. will be useful as natural antioxidants and functional food sources.

시료추출의 최적 조건을 알아보고자 각각 추출 용매별, 농도별, 시간별로 비교하였다. 먼저 추출용매별로 비교한 결과물 추출물에서 36.2 mg/g, 60% ethanol, 60% methanol, 60% acetone 추출물에서 각각 42.7, 40.3, 39.6 mg/g의 함유량을 나타냈다. 따라서 체리 세이지를 60% ethanol에서 24시간 추출하는 것이 가장 효율적이라 판단되었다. 한편 생리활성 효과는 추출물의 농도를 $200{\mu}g/ml$로 조절하여 실험하였다. DPPH에 대한 전자공여능은 60% ethanol 추출물에서 66.3%로 나타났으며, ABTS radical decolorization을 측정한 결과 60% ethanol 추출물에서 97.6%로 나타났다. Antioxidant protection factor는 60% ethanol 추출물에서 2.26 PF로 나타났으며, PF와 같이 지용성 물질의 항산화력을 나타내는 TBARS값은 control값이 $0.62{\times}10^2{\mu}M$로 나타났고, 60% ethanol 추출물에서 $0.29{\times}10^2{\mu}M$의 TBARS값을 나타났다. Xanthine oxidase 활성억제 효과는 78%의 저해율을 나타냈고, ACE 활성억제 효과는 나타나지 않았다. $\alpha$-Amylase 저해활성을 측정한 결과, 60% ethanol 추출물에서 7.6%의 낮은 저해율을 나타내었으며, H. pylori균에 대한 항균활성은 50, 100, 150, $200{\mu}g/ml$ 농도별로 각각 10, 12, 13, 15 mm의 clear zone을 형성되었다.
