Cutleaf teasel (dipsacus laciniatus L.) is an invasive plant that is spreading through natural and disturbed areas. Teasel grows for two or more years as a rosette which stays green late in the growing season and begins growth earlier in spring than its native competitors. The purpose of this study was to find a time both seasonally and in cutleaf teasel’s life history when herbicides could be applied to decrease teasel with the least impact on the surrounding vegetation. We tested the effects of three different herbicides (glyphosate (Round-UpTM), triclopyr amine (GarlonTM), and clopyralid (LontrelTM)) on cut and uncut teasel at three different times of the year (July and October 2005, and April 2006) near Clinton Lake in Dewitt Co. Illinois. Photosynthetic measurements were taken before application to determine teasel’s susceptibility to the herbicides, and we harvested seed heads and rosettes in late October 2006. Results indicated teasel was photosynthetically active at all three application times. Cutting before herbicide application had no significant effect on the number of seeds produced or the dry weight of the rosettes. Herbicide treatment in April significantly reduced the amount of seeds produced, but there were no significant differences among the three herbicides. Clopyralid application in April significantly reduced rosette biomass, but none of the herbicides significantly affected rosette biomass at the other two times. Our studies suggest herbicide application early in the growing season may be beneficial in controlling the spread of teasel, and that mowing at the time of spraying will not increase effectiveness of the herbicide.

EFFECTS OF dipsacus ASPER AND VITAMIN E ON THE SS NEURONS IN THE HIPPOCAMPAL FORMATION OF RAT MODELS OF ALZHEIMER'S DISEASE

引用

Academic Journal of Xi'an Jiaotong University 2002年第2期14卷 140-143页

作者：冯改丰胡海涛王唯析钱亦华任惠民胡晓丹刘朝晖 Department of Human Anatomy Medical School of Xi'an Jiaotong University

Objective To study the effects of dipsacus Asper and Vitamin E on the SS neurons in the hippocampal formation of rat models of Alzheimer’s Disease (AD). Methods Established rat models of AD by giving water containing AlCl 3, then treating them with dipsacus Asper and Vitamin E(VE) for three months, observed the changing condition of rats’ memory through behavior tests, and studied changes of SS neurons in hippocampal formation with immunohistochemical ABC method. Results 3 months after treatment, behavior tests showed that rats’ memory was improved and the SS neurons in each region of hippocampal formation were increased, In CA1,CA2,CA3 and dentate gyrus, there were significant differences among treated groups and control group( P dipsacus Asper and Vitamin E can restore the SS neurons in AD models and SS neurons in hippocampal formation are related to AD’s cause and development.

中国药科大学学报 1993年第5期24卷 281-282页

作者：杨尚军吴知行任海红上海静安中药厂中国药科大学天然药物化学教研室

对川续断dipsacus asperoides *** et ***根中的二个生物碱斑点,进行跟踪分离并纯化,并经光谱学方法鉴定其结构为venoterpine(B)及cantleyine(B),并非文献中所载的龙胆碱(gentianine)。
