본 발명은 종자 소재의 발아율을 측정하여 시료에 대한 피부 세포 재생력을 가시적으로 평가하는 방법에 관한 것이다. 보다 상세하게, 본 발명에 의한 피부 세포 재생력을 평가하는 방법은 세포에 시료를 처리한 후 배양하여 흡광도 측정 방법 등을 통해 수치로만 표현 가능하였던 종래의 피부 재생력 평가방법을 개선하여, 종자 소재에 시료 처리후 종자가 발아했을 시 종자의 무게 및 싹의 길이를 관찰함으로써 시료가 가진 피부 세포의 재생력을 가시화하여 평가하는 방법으로서 이를 통해 세포 배양 기술이나 특수한 기기 및 장치의 보유 여부와 상관없이 일반인도 시료의 세포 재생에 관한 효과를 쉽게 평가할 수 있다. 피부세포, 재생력, 발아, 종자, 가시화
Abstract:
PURPOSE: A novel soil microorganism and oxidoreductase isolated from the microorganism are provided to ensure saccharide decomposition of natural products and to obtain various flavonoid aglycons. CONSTITUTION: A method for preparing flavonoid aglycons comprises a step of using Rhizobium sp. GIN611(KCTC11708BP) or cell extract thereof. The strain is isolated from soil. The flavonoid aglycon is prepared using Rhizobium sp. GIN611-derived oxidoreductase as a biocatalyst. The flavonoid aglycons are prepared by decomposing saccharides from flavonoid glycoside.
