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 250 g and stems of 300 g with 1,3-butylene glycol (1,3-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$0.05, and refractive index was 1.375$\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$0.05. Oil of yew separated from seeds, and extracted polysaccharide high purity from fruits. As a result, specific gravity of oil was 0.987, and obtained 40％ of yield. Total polyphenols amount of yew extract is detected 0.563％ in leaves, 0.325％ in stems, whereas total tannins amount contained 0.054％ and 0.037％ each in leaves and stems. As effect in cosmetics, the anti-oxidative effect by DPPH method is 75.0％ in leaves, and stems was 64.0％. Collagen synthesis rate was shown high activity by 54.16％ in stem's extract, 33.18％ in leaves' extract. Also, PPE-inhibitory activities were 13.7％ and 23.5％ each in leaves and stems. Anti-inflammatory effect of yew seed oil displayed superior effect of 41 ％ than control. Polysaccharide's molecular weight that is gotten from fruits was 5$\times$10$^4$~ 3$\times$10$^{5}$ dalton, and got 20.0$\pm$5％ of yield.

Yew (Taxus cuspidata Sibe) selected cultivation as drug, food and decorative plant in Gyong-gi province in Korea. To extract the water soluble active ingredients, as a extracting method, there was extracted with 20g of dried seeds with each 20g of butylene glycol(BG) and propylene glycol(PG), and 40 mL of water mixing 72 hours at $40{\pm}5^{\circ}C$, and then they were filtrated by 400 mesh. Appearance of extract of seeds was pale brown, $pH=4.5{\pm}0.5$, $gravity=1.013{\pm}0.05$, a reflective $index=1.373{\pm}0.05$, and yield=75%. Also, to extract the high purity oil from seeds, it minutely pulverized the dried seeds and added the hexane, mixing 2 hours at $20{\pm}57^{\circ}C$. And then, this filtrated it with 400-mesh. It got the purified oil through evaporating them at $55^{\circ}C$ during under vacuum. As the results, appearance was slightly brown, gravity=0.922 acid value=0.12, saponification value=192, and it should be obtained the $40{\pm}5%$ of yield. As the efficacy evalution of cosmetic field, the antioxidative activities by NBT method were stronger 86.0% from extract of talus seeds than 52.0% from green tea extract and 35.0% from skullcap extract as well as the antioxidative activities by DPPH method were stronger 93.7% from extract of seed than 60.3% from extract of green tea and 27.1% from extract of skullcap. These are more effective than other plant extracts. The collagen synthesis rate on the activating fibroblast for Taxus cuspidata Sibe extract showed 35.43%. As the activity of the skin elasticity, PPE(porcine pancreatic elastase)-inhibitory activities of talus extract was 50.8%. Anti-inflammatory activity was more effective to be taken 41.1% of taxus seed oil than 24.2% of steady glycyrrhetinate (SG) as a control.
