利用扫描电镜对伞形科滇芎属7个种的花粉与叶表皮形态进行了观察与研究,其中3种滇芎属植物的花粉形态为首次报道,7种叶表皮微形态为首次报道,为滇芎属的种间关系与属下系统发育研究提供参考资料。结果表明:(1)滇芎属7种植物花粉形态分... 利用扫描电镜对伞形科滇芎属7个种的花粉与叶表皮形态进行了观察与研究,其中3种滇芎属植物的花粉形态为首次报道,7种叶表皮微形态为首次报道,为滇芎属的种间关系与属下系统发育研究提供参考资料。结果表明:(1)滇芎属7种植物花粉形态分为菱形、椭圆形、近矩形等3种,极面观的形状则有三角形、三角圆形以及钝三角形;花粉极轴与赤道轴的比值P/E为1.22~2.07,体积大小指数为16.59~19.26;萌发孔位置为角萌发孔,赤道面纹饰皆为脑状纹饰。(2)滇芎属7种植物叶表皮细胞轮廓均不清晰,只有木里滇芎的叶表皮细胞为规则的多边形,角质膜具不规则的条纹纹饰;滇芎、丽江滇芎、紫脉滇芎、波棱滇芎的气孔只分布于远轴面;气孔的形态为椭圆形或卵圆形,气孔器长为14.90~25.40μm,宽为9.76~17.49μm;依据叶表皮的微形态特征,可以将滇芎属的各个物种区分开来。(3)波棱滇芎和小滇芎为两个独立的物种,亲缘关系最近。(4)花粉形态和叶表皮微形态对解决滇芎属的种间分类问题具有重要参考价值。 展开更多

Growth retardation affects the health and production of livestock,while overexertion can cause sudden cardiac arrest.Both cases are considered to be metabolic disorders and are detrimental to livestock production.Effective measures for relieving or treating these disorders are scarce.However,Pimpinella thellungiana H.Wolff(P.thellungiana),a medicinal herb,has been reported to relieve growth retardation and overexertion in ethnopharmacological clinical trials.This paper summarizes and classifies a total of 106 bioactive compounds that were isolated and identified from P.thellungiana,including flavonoids,simple phenylpropanoids,coumarins,volatile compounds,and simple polyphenols,and discusses its pharmaceutical benefits,including its growth-promoting,antioxidant,anti-inflammatory,anti-atherosclerotic,and hepatoprotective properties.The nutrition,metabolism,biological activities,and pharmacological effects of the principal compounds of P.thellungiana in livestock are reviewed,as well as their potential molecular targets and metabolic signaling pathways in which these compounds are involved.However,the pharmacological and toxicological effects of some compounds have not been well documented,and further investigations of the bioactive compounds are needed.Such studies are crucial for the development of natural drugs or feed additives from P.thellungiana to alleviate growth retardation and mitigate injuries from overexertion in livestock. 展开更多
