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.

Large-scale cultures of plant cell, tissue, and organ have been achieved by using BTBB. When different sized BTBBs (5 L, 20 L, 100 L, 300 L, and 500 L) were tested for the culture of yew cells (Taxus cuspidata Sieb. et Zucc.), cell growth increment reached to 94.5% in SCV after 24 days of culture with 30% of inoculation cell density. However, there were some variations in the production of taxol and its derivatives among the BTBBs of different size. Approximate 4 ㎎/l of taxol and 84 ㎎/l of total taxanes were obtained by using a 500L BTBB after 6 weeks of culture. With a 20L BTBB, about 20,000 cuttings of virus-free potatoes (cv. Dejima) could be obtained by inoculating 128 explants and maintaining 8 weeks under 16 hr light illumination. The frequency of ex vitro rooting of the cuttings revealed as more than 99% under 30% shade. By incorporating two-stage culture process consisting of multiple bulblet formation in solid medium and bulblet development in liquid medium, mass propagation of lily through bioreactor seemed to be possible. In the case of 'Marcopolo', the growth of mini-bulblets in BTBB was nearly 10 folds faster than that of the solid medium. Time course study revealed that maximum MAR yield of ginseng (Panax ginseng C. A. Meyer) in a 5 L and 20 L BTBB after 8 weeks of culture was 500 g and 2.2 ㎏, respectively. By cutting the MAR once and/or twice during the culture, the yield of root biomass could be increased more than 50% in fresh weight at the time of harvest. With initial inoculum of 500 g of sliced MAR in a 500 L BTBB, 74.8 ㎏ of adventitious root mass was obtained after 8 weeks of culture. The average content of total ginseng saponin obtained from small-scale and/or pilotscale BTBBs was approximately 1% per gram dry weight. Based on our results, we suggest that large-scale cultures of plant cell, tissue, and organ using BTBB system should be quite a feasible approach when compared with conventional method of tissue culture.
