Abstract
Yew (Taxus cuspidata Sieb.) chose that grow as medicine, food, decorative plant in Korea's Kyong-Gi province surroundings. Extracts of yew extracted leaf of 250g and stems of 300g with 1,3-butylene glycol (l,3-BG), propylene glycol (PG) and water. As results, external appearance of leaf extract of yew was slightly brown clear extract. The pH was 5.3${\pm}$0.5, and specific gravity was 1.012${\pm}$0.05, and refractive index was l.375${\pm}$0.05. Also, appearance of stem's extract was slightly brown clear extract, and the pH was 5.4${\pm}$0.5, and specific gravity was 1.016${\pm}$0.05, and refractive index was 1.358${\pm}$0.05. Oil of yew separated from seeds, and extracted polysaccharide high purity from fruits. As a result, specific gravity of oil was 0.987, and obtained 40.0% of yield. Total polyphenols amount of yew extract is detected 0.563% in leaves, 0.325% in stems, whereas total tannins amount contained 0.054% and 0.037% each in leaves and stems. As effect in cosmetics, the anti-oxidative effect by DPPH method is 75.0% in leaves, and stems was 64.0%. Collagen synthesis rate was shown high activity by 54.16% in stem's extract, 33.18% in leaves' extract. Also, PPE-inhibitory activities were 13.7% and 23.5% each in leaves and stems. Anti-inflammatory effect of yew seed oil displayed superior effect of 41% than control. Polysaccharide's molecular weight that is gotten from fruits was 5${\times}$10$^4$-3${\times}$10$\^$5/ dalton, and got 20.0${\pm}$5% of yield.
주목은 국내의 경기도 일대에서 약용, 식용, 관상수로써 재배한 것을 선정하였다. 주목의 250g의 잎과 300g의 줄기추출물은 부틸렌글리콜(BG), 프로필렌글리콜(PG)과 물을 사용하여 추출한 결과, 주목의 잎 주출물의 성상은 연한 갈색의 맑은 액으로, pH는 5.3$\pm$0.5, 비중은 1.012$\pm$0.05, 굴절율은 1.375$\pm$0.05이었다. 또한, 줄기 추출물의 성상은 연한 갈색의 맑은 액이었으며, pH는 5.4$\pm$0.5, 비중은 1.016$\pm$0.05, 굴절율 1.358$\pm$0.05이었다. 주목의 씨앗으로부터 오일을 분리하였고, 과육으로부터 폴리사카라이드를 고정제 추출하였다. 주목의 씨앗으로부터 얻어진 오일의 비중은 0.987, 40$\pm$5%의 수율을 얻을 수 있었다 주목추출물의 총 폴리페놀량은 잎에서는 0.563%, 줄기에서는 0.325%가 검출된 반면, 총 탄닌량은 잎과 줄기에서 각각 0.054%와 0.037%를 함유하였다. 화장품에서의 효능으로써 DPPH 방법에 의한 항 산화효과는 잎에서는 75.0%, 줄기에서는 64.0%였다. 파이브로블레스트에 의한 콜라겐 합성율은 줄기추출물은 54.16%, 잎 추출물은 33.18%로 비교적 높은 활성을 보였다. 또한, PPE-inhibiton의 활성은 잎과 줄기에서 각각 13.7%와 23.5%였다. 주목씨앗 오일의 항 염증 효과는 대조군보다 41%의 우수한 효과를 나타내었다. 과육으로부터 얻어진 polysaccharide의 분자량은 5${\times}$$10^4$-3${\times}$$10^{5}$ dalton이었으며, 20.0$\pm$5%의 수율을 얻었다.
