상황버섯의 화학성분 및 생리활성 효과 = Chemical Compounds and Biological Activity of Phellinus baumii

다국어 초록 (Multilingual Abstract)

Chemical compounds, hydrogen peroxide and nitrite scavenging activities of Phellinus baumii (PB) were investigated to expand the utilization of PB as functional food material. Total mineral contents of PB was 534.3 mg% and potassium was the highest content being 224 mg%. Total and reducing sugars were 56.2% and 9.8%, respectively. The contents of free amino acids (FAAs) were in a range of 16.9∼765.5 mg% with the major FAAs of phenylalanine, aspartic acid, glutamic acid, leucine, serine and valine. The contents of total phenolic compounds in methanol and hot water extracts of PB were 33.3 and 20.7 mg/100 mL, respectively and were higher than those of other solvent extracts. Hydrogen peroxide scavenging activity (80%) of methanol extract at 10 g/mL for 30 min was similar to tocopherol (83.1%) as control. Nitrite scavenging activity of extracts of methanol and hot water at 500 mg/mL and pH 1.2 were 57.3% and 51.8%, respectively and then their effects were increased by lowering pH. The present results showed that the methanol and water extracts of Phellinus baumii exhibited strong hydrogen peroxide and nitrite scavenging activities.

상황버섯의 활용성을 증진시키기 위하여 상황버섯의 화학성분과 그 추출물의 과산화수소 및 아질산염 소거능을 측정하였다. 상황버섯의 총 무기질 함량은 534.3 mg%였으며, K는 224 mg%로 가장 높았고, 총당과 환원당은 각각 56.2 %와 9.8%였다. 유리아미노산 함량은 16.9∼765.5 mg%범위였으며, 주요 유리아미노산은 phenylalanine, aspartic acid, glutamic acid, glutamic acid, leucine, serine 및 valine이었는데, 그 중에서 phenylalanine의 함량이 765.5 mg%로 가장 높았다. 상황버섯 메탄올과 열수추출물의 총 페놀성 화합물은 각각 33.3 mg/100 mL와 20.7 mg/100 mL로서, 다른 용매추출물에 비하여 높은 수치를 나타내었다. H2O2 소거효과는 methanol 추출물 10 g/mL에서 30분간 반응하였을 때 80%를 나타내어 대조구인 tocopherol 83.1%와 비슷하였다. 아질산염 소거효과는 낮은 pH에서 높았으며, pH 1.2에서 물과 methanol 추출물 500 mg/mL은 각각 57.3%와 51.8%를 나타내었다. 결론적으로 상황버섯의 물과 메탄올 추출물은 H2O2와 아질산염 소거에 우수한 효과를 나타내었다.
