Abstract

To elucidate the changes in physiological activities of Scutellariae baicalensis by heating, composition analysis with HPLC and evaluation of physiological activities of extracts were conducted. HPLC analysis of CW(water extract at room temperature) and CHW(heat treated CW) indicated that two distinctive peaks in the HPLC chromatogram were disappeared after boiling and additional peak was newly observed. This observation suggested that certain chemical changed in the extract occurred by heat treatment. In the estimation of physiological activities, CW showed higher ACE inhibiting activity than CHW. In the case of cytotoxic activity against cancer cells, CW exhibited higher activity than CHW against CCL-185. On the other hand, CHW showed higher activity than CW against HeLa, SNU-601 and HepG2. In addition, CHW showed the inhibitory effect on melanogenesis (80% inhibition) while CW did not show any activity.

황금에 대한 수 추출물의 열 변환에 의한 생리활성 변화를 보기 위하여 HPLC를 통한 peak분석과 기능성 평가를 하였다. 열처리 전의 시료 (CW)와 열처리 후의 시료 (CHW)간의 peak분석에서 CW와 CHW의 비교 시 A와 B가 없어지고 열처리 후에 C라는 다른 물질의 peak가 형성됨을 알 수 있었다. 또한, 전체적인 기능성 평가에서 항산화성에서는 CW와 CHW 별 차이가 없었고, 항고혈압 활성은 CW가 높았다. 항암성에 있어서 폐암에서는 CW가 높았고, 위암, 간암, 후두암 등에는 CHW가 높게 나왔다. 그리고, 멜라닌 생성세포의 멜라닌 생성 억제는 CHW에서 약 80%로 매우 높게 나타났다. 결론적으로 열처리를 통한 시료 내 구성성분의 변환이 기능성 차이를 보여주며, 이는 새로운 열 변환 물질의 생성 때문으로 판단된다. 이들 변화된 물질은 황금의 주성분인 Baicalin 외의 물질이 열 변환 된 것으로, 생성된 물질에 대한 구조분석이 필요한 것으로 사료된다.
