Study on the antioxidant, anti-inflammatory and Preservative features Water Chestnut
본 연구는 70 % 에탄올 추출물에서 추출한 Water Chestnut의 항산화, 항 염증 및 방부 효과를 평가하고자 하였다. RAW 264.7 세포를 사용하여 조사한 마름열매 추출물의 독성은 세포 생존율의 90 % 이상을 나타내었으며 폴리페놀 추출물의 총 함량은 353.1 ± 5.6 ㎎ / g이었고 플라보노이드 총 함량은 26.2 ± 1.4 ㎎ / g이었다. 항산화 활성을 확인하기 위한 1, 1-diphenyl-2-picryl-hydrazyl(DPPH) 라디컬 감소는 마름 열매 추출물 농도 1 ~ 1000 (㎍ / ㎖)범위에서 각각 17.0 ± 2.8 % ~ 88.6 ± 0.6 %의 감소효과를 보였고 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid(ABTS) 라디칼의 제거 범위는 각각 2.3 ± 0.8 % ~ 93.9 ± 0.2 %였다. 활성 산소종 (ROS)에서의 효과는 1, 10, 100 (㎍ / ㎖), 100 ㎍ / ㎖ 농도에서 p <.01의 유의 한 감소를 보였다. 1, 10, 100 (㎍ / ㎖) 농도의 Nitric Oxide (NO) 생성량을 측정 한 결과, 유의 한 (p <.001, p <.01)의 감소가 나타났다. 미생물에의 방부효과를 확인하기 위한 페이퍼 디스크를 사용하는 항 박테리아 기능과 페트리 필름을 사용하는 방부제 특성에 대해서는 유의한 효과가 나타나지 않았다.
The purpose of this study was to assess the antioxidant, anti-inflammatory and preservative effects of Water Chestnut from 70% ethanol extracts.
The toxicity of extracts from Water Chestnut investigated using the RAW 264.7 cell showed higher than 90% of cell survival rate. The total content of polyphenol ethanol extract was 353.1 ± 5.6 ㎎/g, while the total content of flavonoid was 26.2 ± 1.4 ㎎/g. With a concentration level of 1 ∼ 1000 (㎍/ ㎖) ethanol extract of Water Chestnut the range of removal of 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) radicals was 17.0 ± 2.8% ∼ 88.6 ± 0.6% respectively and the range of removal of 2,2′ -azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals was also 2.3 ± 0.8 % ∼ 93.9 ± 0.2 % respectively. There were decreases in reactive oxygen species(ROS) generations ethanol extracts of Water Chestnut 1, 10, 100 (㎍/㎖) and significance decrease at 100 ㎍/㎖ (p<.01).
As a result of measuring the Nitric Oxide(NO) generation amount of Water Chestnut extract 1, 10, 100 (㎍/㎖) concentration exhibited significant (p<.001, p<.01) decreases.
For the anti-bacterial features using a paper disk and the preservative features using petri film, no significance was found and therefore water chestnut extracts had not anti-bacterial or preservative features.
