Analysis of physiological activities of wild Flammulina velutipes

야생 팽나무버섯의 생리활성 분석

In this study, for the development of useful food materials, the proximate composition(total carbohydrates, crude fiber, crude protein, fat and ash) and biological activities(electron donating activity, total polyphenol contents, ACE inhibitory and ${\gamma}$-glucosidase inhibitory effects) were determined in the Garlmoe and the four wild Flammulina velutipes. As a results, the dry matter of mushrooms contained large amounts of carbohydrates, from 65.9 to 70.5 g/100g dry weight. the wild collected Flammulina velutipes proved to be an especially good source of crude fiber(7.9~18.1 g/100 g dry weight). Crude protein, fat, and ash contents of the mushrooms ranged 17.1~21.3, 4.1~5.2, and 5.7~8.4 g/100g dry weight, respectively. The electron donating activity ranged from 63.35 to 69.31% and total polyphenol contents ranged from 9.83 to 11.14 mg/g in these mushrooms. ACE inhibitions were high in Garlmoe and CBMFV-02 strain. ${\alpha}$-glucosidase inhibition was the highest in CBMFV-01(46.56%) strain and lowest in Garlmoe(15.91%).

충북지역에서 수집한 야생 팽나무버섯의 식품소재로의 가능성을 조사하기 위해 동결 건조한 후 일반성분 및 전자공여능, 총폴리페놀 함량, ACE 저해도와 ${\alpha}$-glucosidase 저해도등 생리활성을 분석하였다. 대조군으로 갈뫼팽이버섯과 4종의 수집 야생 팽나무버섯의 일반성분은 건물중으로 분석하였으며, 조단백질은 17.1~21.3 g/100g, 조지방은 4.1~4.9g/100g, 탄수화물은 65.9~70.5g/100g, 조섬유는 7.9~18.1g/100g, 조회분은 5.7~8.4g/100g 범위를 나타내었다. 전자공여능은 63.35~69.31%로 시료간 큰 차이가 없는 것으로 나타났으며, 총폴리페놀 함량은 9.83에서 11.14 mg/g로 대조구와 유사하였다. ACE 저해도는 대조구인 갈뫼 팽이버섯과 수집종인 CBMFV-02가 각각72.91%, 71.44%로 높은 값을 나타내었으며, ${\alpha}$-glucosidase 저해도는 CBMFV-01이 46.55%로 가장 높은 값을 나타내었다.
