Summary:This study examined changes in antioxidant activity as well as contents of rosmarinic acid, homoplantaginin, and luteolin, which is the main substance of Salvia plebeia R. Br. (SPR) known to have anti-inflammatory efficacy, according to drying, blanching, and fermentation conditions. Rosmarinic acid content was 16.42 mg/g upon hot-air drying and 10.19 mg/g upon hot-air drying after blanching, and there was no significant difference in the case of leaf and root freezing or cold-air drying. Rosmarinic acid content was 8.69 and 8.15 mg/g in the case of air-drying in the shade and freeze-drying, respectively, and decreased to 0.05 mg/g or undetected after fermentation. SPR processed by freeze-drying, cold-air drying in the shade, and hot-air drying showed ABTS radical scavenging ability over 98.5% at a concentration over $500{\mu}g/mL$ as well as excellent radical scavenging ability of 87.3% in the case of hot-air drying after blanching. Root showed lower ABTS radical scavenging ability than leaves. SOD-like activity was measured to be 6.1~27.8% at a concentration of $1,000{\mu}g/mL$, which was significantly difference from ABTS radical scavenging ability. As rosmarinic acid and homoplantagine, an anti-inflammatory material contained in SPR, are almost undetectable after oxidation fermentation during processing, hot-air drying after blanching or drying seems to be suitable to develop SPR as a functional substance. 본 연구는 배암차즈기를 건조, 데침 및 발효에 따라 항염증 효능성분인 rosmarinic acid, homoplantaginin, luteolin의 함량 변화와 항산화 활성을 조사하였다. Rosmarinic acid는 열풍건조 시 16.42 mg/g, 데친 후 열풍건조 시 10.19 mg/g 순으로 검출되었으며, 동결건조 한 잎과 뿌리는 유의적인 차이가 없었다. 음건 및 동결건조 시에는 각각 8.69와 8.15 mg/g으로 유의성이 인정되었으며, 발효 후에는 0.05 mg/g으로 감소하거나 검출되지 않았다. 동결건조, 음건 및 열풍건조 한 배암차즈기는 $500{\mu}g/mL$의 농도에서 98.5% 이상의 ABTS radical 소거능을 나타내었으며, 데친 후 열풍건조 시에도 87.3%의 우수한 radical 소거능을 나타내었다. 뿌리는 잎에 비하여 ABTS radical 소거능이 낮았다. SOD 유사활성은 $1,000{\mu}g/mL$ 농도에서 6.1~27.8%로 측정되어 ABTS radical 소거능과 차이가 있었다. 배암차즈기에 함유되어 있는 주요 물질이며 항염증 효능 물질로 알려진 rosmarinic acid와 homoplantaginin은 차발효에 의해 거의 소실되기 때문에 배암차즈기를 기능성 차 또는 가공식품 원료로 개발하기 위해서는 차발효(산화발효)보다 동결, 냉풍 및 열풍건조가 적당할 것으로 판단된다.
