Genus llex L.: Phytochemistry, Ethnopharmacology, and Pharmacology

The genus Ilex L. has been used as remedies in traditional Chinese medicine in Aquifoliaceae and beverages for thousands of years due to abundant pharmaceutical bioactivities. There are 600 species in genus IlexL. containing various compounds such as terpenoids, saponins, glycosides, etc. Three species, L cornuta, I. chinensis, and L rotunda have been admitted in Chinese Pharmacopoeia 2015 to treat dyspepsia, stomatitis, and hyperactivity cough and protect the liver and kidney. Recent studies showed that several species have been daily drunk to promote human health and prevent cardiovascular diseases in the folk. Here we reviewed the genus Ilex L. in phytochemistry, ethnopharmacology, and pharmacology.

英国无刺冬青苗期多点区域试验

引种的国外常绿绿化新优植物英国无刺冬青,其12、a生种苗分别种植在我国长江南北的5个不同区域,2 a后对其苗期生态适应性等进行初步评价。结果表明,在陕西省的延安及河北省的邢台两地引种的英国无刺冬青小苗不能在当地正常越冬,受冻害而整株死亡;分种在云南省的昆明、江苏省的南京这2个试验点的小苗生长良好,越冬和越夏未见异常;山东省济南试验点的小苗可安全越冬,但遇夏季极端高温,有部分植株死亡。英国无刺冬青小苗在昆明、南京、济南3点种植的新梢高生长与粗生长差异极显著,以济南地区的粗生长量最大,昆明的最小;以南京地区的高生长量最大,昆明的最小。济南和南京两地与昆明的相比,在粗生长与高生长上均达到差异显著和极显著水平;新梢叶片数以南京的为最高,昆明的最低。经分析,温度是影响英国无刺冬青小苗成活与否的关键,日照长度及降水量对其生长量有很大影响。
