Both the leaf of lespedeza dahurica ( laxm . ) schindl . and the leaf of sophora flavescens ait . which live in the alkaline land of songnen plain , and the leaf of amorpha fruticosa linn . which grows in the land for salt enduring species sieving were made into paraffin sections 对生长在松嫩平原盐碱地( ph = 8 . 5 - 9 )上的兴安胡枝子和苦参的叶，以及生长在当地抗盐树种筛选试验田( ph = 8 . 5 - 9 )上的紫穗槐的叶制作了石蜡切片，并对这些切片作了光镜观察和结构植物学分析。
A survey of literature shows that little study has been done on uptake of pollutants by plants from the polygonaceae , and that the reports about their physiological and biochemical characteristics under heavy metal stress were sporadically seen . a batch of sand culture and soil culture experiments were carried out to investigate heavy metal and radiocesium uptak e and accumulation by rumex acetosa linn , polygonum microcephalum d . don , and rumex hastatus d . don widely distributed on copper mining areas , and their physiological and biochemical characteristics under cu zn stress , as well their potentials in application to phytoremediation 本论文以广泛生长于铜矿区的蓼科植物酸模、小头蓼和戟叶酸模为试验材料，运用砂培、土培等方法，研究它们对重金属( cu 、 zn )以及放射性核素( ~ ( 134 ) cs )的吸收和积累特性以及cu 、 zn胁迫条件下它们的生理生化特征，初步探讨它们在无机污染物污染土壤植物修复中的应用潜力。
We have sifted 103 medicinal plants , roughly identified 17 plants might contain antifungal proteins . antifungal protein was purified from cassia sophera linn , by extraction , fraction with ( nh _ ( 4 ) ) _ ( 2 ) so _ ( 4 ) , cation - exchange chromatography of cm - sepharose ff xk 26 , the first cation - exchange chromatography of mono s and the second one , followed by gel filtration of superose 12hr 对茳芒决明进行了抗菌蛋白的分离纯化：经粉碎、磷酸缓冲液浸提、硫酸铵沉淀、 cm - sepharoseffxk26阳离子交换层析、两次monos阳离子交换层析、 superose12hr分子筛层析可得到具抗真菌活性的蛋白。
In this paper , the brief history and the current condition in the classification of the genus acer linn . have been reviewed . i have also compared the precision of the ancestors ' studies and then studied the classificating evidence , the law of origin and evolution and geographical distribution . by identifying and studying the specimens , 1 ensure that there lie 20 species and subspecies and 8 varieties which belong to 3 subgenus in henan province . i add 3 species and 2 varieties which were not recorded in flora of henan such as acer tegnentosum maxim . a . tsinglingense fang et hsieh , a . shensiense fang , a . buergerianum miq . var . ningpoense ( hance ) rehd 作者通过对河南槭属植物的分类研究，确认了本省槭属植物共计20种、 1亚种和8个变种，隶属于3亚属12组，增补了《河南植物志》中未记载的但河南有自然分布的3个种、 2个变种：青楷槭acertegnentosummaxim .秦岭槭a . tsinglingensefangethsieh 、陕西槭a . shensiensefang 、宁波三角槭a . buergerianummiq . var . ningpoense ( hance ) rehd .和蒿苹四蕊槭a . tetramerumpaxvar . haopingensefang .订正了《河南植物志》和《河南种子植物检索表》中一些分类学问题。
Based on the morphological and phytochemical investigations , comparative studies on the antidepressant action of the ethanol extracts of hypericum perforatum linn > h . faberi r . keller and h . sampsonii hance ( sect . hypericum ) were conducted . the forced swimming and mouse - tail suspension tests in mice show that the extracts from these 3 species have antidepressant actions 在形态学研究和化学研究基础上，对贯叶连翘及与之亲缘关系相近的贯叶连翘组扬子小连翘、元宝草醇提物的抗抑郁作用进行比较研究，采用小鼠尾悬挂试验、强迫游泳试验，结果表明三者均可对抗小鼠的失望行为，具有抗抑郁作用。
