Abstract

Acanthopanax senticosus is a common Asian herb also known as "Siberian Ginseng". It is often used as a traditional herbal medicine for reducing damage in the liver, kidney, bone and muscle. In the present study we investigated the ferric reducing/antioxidant power and total phenolic contents of the ethanol-/water-extracts obtained from the stems and leaves of Acanthopanax senticosus. Osteoblast cellular proliferation was evaluated using the MTT and alkaline phosphatase activity assays in the human osteoblast-like MG-63 cell line. Acanthopanax senticosus extracts exerted remarkable ferric reducing/antioxidant power and contained high amount of phenolics. Among the extracts the stem-/ethanol-extract showed the highest antioxidant activity and total phenol content. Interestingly a highly positive correlation was found between antioxidant activity and total phenol content (p < 0.01). Proliferation of MG-63 osteoblast cells was highest in the stem-/ethanol-extract and alkaline phosphatase activity significantly increased in the water-extract of the stems (p < 0.05). These findings suggest that Acanthopanax senticosus extracts have antioxidant activity for preventing oxidative stress-related diseases and may have beneficial effects on bone health through the proliferation of osteoblast cells.

본 연구에서는 가시오가피 추출물의 부위, 추출 용매, 산 가수분해 전처리에 따른 항산화 활성을 알아보고자 FRAP assay를 실시하였으며, 총 페놀 함량을 측정하고, 가시오가피 추출물의 항산화 활성과 총 페놀 함량간의 상관관계를 분석하였다. 또한 가시오가피 추출물 처리가 조골세포 증식률과 alkaline phosphatase 활성에 미치는 영향을 분석하여 가시오가피의 골다공증 예방 가능성을 규명하고자 하였다. 연구결과 가시오가피에 함유된 총 페놀 함량과 FRAP법으로 측정된 항산화 활성 간에 양의 상관관계가 있는 것으로 나타났으므로, 가시오가피의 항산화 활성은 함유된 폴리페놀에 의해 나타나는 것으로 풀이된다. 그러나 가시오가피에 함유된 폴리페놀 함량과 항산화 활성은 가시오가피의 부위와 추출 용매 및 산 처리 여부에 따라 차이가 나는 것으로 나타났다. 또한 가시오가피의 에탄올 추출물이 물 추출물에 비하여 조골세포 증식을 유의적으로 증가시켜주는 것으로 나타났다. 가시오가피의 물 추출물은 조골세포에서 염기성 인산 분해 효소의 활성을 유의적으로 증가 시켰다. 이는 가시오가피의 부위와 추출 용매 및 전처리 과정에 따라 추출되는 활성 성분의 종류와 양에 차이가 있기 때문으로 풀이된다. 이 결과는 가시오가피의 가공법을 선정하는데 고려되어야 할 중요한 사항으로 사료된다. 본 연구를 통하여 가시오가피의 항산화 활성과 조골세포 증식 효과가 제시되었다. 한국산 가시오가피를 건강 기능 식품 소재로 개발하기 위해서는 동물 실험과 인체 시험을 통한 심도 있는 연구가 수행되어야 할 것이다.
