Background : The purpose of this study was to big strong and root in the disease, many high quality seed of Achyranthes japonica N. selection by fostering, expanding the spread on a farm and raw materials medicines of sources deployment for process is to contribute to increasing farm income. Methods and Results : Collected variety into the mass selection breeding method by head-to-row cultivation, native variety of Hwasoon and Jangheung Jeonnam, was conducted in 2007. Three individual selection in 2010 as it produces the 27 and five individual in 2008 and 2009. From 2010 to 2011, pure line isolation as it cultivated and one foundation group. Promising in 2012, select one system. Replicated yield trial for two years beginning in 2013 a result of the stem length, multiple No. of branches and providing high -quality “No. 1, Jeollanam-do” majority by assigning system name. Naju-si, Yeongam-gun, local excellence by implementing a local adaptability test recognized in two years. To breed a new variety named as a dwelling “ Woogang” of Achyranthes japonica N. the review by fostering december 2015 to be registered. Conclusions : Leaf type is the broad lancet, flowering time is new variety two days than Jangheung native variety delayed. New variety of stem length and main root length are check variety (89㎝, 13.5㎝) of 9㎝ and 2㎝ tall respectively. Seed yields has native variety as much as 35 % compared to the many into 43.5 kg/10a. The ecdysteroids contents of roots was 1.2 times higher compared to check variety (668.1ppm). The dried root yields of the new variety are 285kg/10a a many native variety than 20%.
우슬이 민간요법으로 관절염 치료에 우수한 한약재로 알려진 바 우슬 추출물이 cathepsin B 에 대한 저해력을 검토하기 위하여 각종 용매로 우슬 추출물을 순차 분획하고 분획 추출물에 대하여 cathepsin B에 대한 저해활성을 검토하였으며 우슬의 지표물질인 20-hydroxy ecdysone이 추출분획에 검출되는지 TLC 및 HPLC를 이용하여 분석하였으며 우슬의 지표물질이 cathepsin B에 대한 저해활성여부를 확인한바 다음과 같은 결
