本文总结了2020年发表的中国蜘蛛新分类单元和中国分类学者发表的国外蜘蛛新分类单元。基于国内标本, 2020年共发表中国蜘蛛223个新分类单元, 其中中国学者在12种期刊的56篇文章中命名了1新亚科、12新属和201新种, 国外学者命名了9新种, 合计210新种。云南是发现新种数量最多的省份, 占全国发现新种总数的38.1%。基于缅甸等12个国家标本, 2020年中国分类学者发表了外国蜘蛛95个新分类单元, 包括2新科、7新属和86新种。本文还总结了过去5年中国分类学者对全球蜘蛛分类的贡献, 2016‒2020年有1位中国学者发表771个新分类单元。  相似文献

An investigation of Inula helenium, I. royleana, I. salicina and I. bifrons afforded in addition to known sesquiterpene lactones 20 new lactones, the eudesmanolides 3, 6 and 8–12, the germacranolides 14–18 and 20–22, the guaianolides 23 and 25, the pseudoguaianolide 26, the xanthanolides 28 and 32 and the cyclopropane analogue 30. Structures and configurations of these new compounds were established by extensive PMR studies and by some chemical transformations. Some of the investigated species contain besides the widely distributed pentaynene 33 several known thymol derivatives together with a new one (40).  相似文献

The investigation of nine Baccharis species afforded, in addition to known compounds, three new clerodane derivatives related to bacchotricuneatin B, two ent-labdane derivatives, two 3-acetoxyflavanones, a benzofuran derivative and a chromene. The overall picture of the chemistry of this large genus is still not very clear.  相似文献

The investigation of twelve further species of the Eupatorium complex affords four new germacrolides and seven guaianolides together with new thymol and p-hydroxyacetophenone derivatives. The structures of these compounds have been elucidated by spectroscopic methods. Chemotaxonomic aspects of these findings are briefly discussed.  相似文献

本文总结了2021年国内外学者发表的中国鳞翅目新分类单元的情况。经过统计, 2021年共发表与中国鳞翅目物种相关的论文104篇, 专著1部, 涉及新分类群230个, 其中新属7个, 新种215个, 新亚种8个; 发表中国新记录属9个、中国新记录种78个(包括2亚种)、新组合31个; 提出4个种的异名, 2个种被赋予新名。新种(亚种)隶属于34科。云南省发表的新物种数和新记录物种数明显高于其他地区, 分别占全国发表总数的36.8%和39.7%。2021年我国南方新物种和新记录种发表数量仍然显著高于北方。  相似文献

The investigation of two further Senecio species afforded two new furanoeremophilanes, four eremophilanolides and a new hydroxyeremophilane. The structures of two furanoeremophilane, isolated before, have been revised.  相似文献

Investigation of a further 27 Euryops species affords, besides known compounds, 55 new furanoeremophilanes together with several other compounds. The configuration of six furanoeremophilanes earlier given as 10β-H has to be changed to 10α-H. Furthermore 9 new eremophilenes were isolated; the configurations of four compounds of this type isolated before have had to be changed. One of the eremophilenes is esterified with 3-methylpent-3(E)-enoic acid, not found before in nature. Two hemiacetals, which are probable precursors of the furanoerephilanes, and a corresponding lactone are also present. Furthermore two benzylic esters, cis-caryophyllene, a bicyclo-germacrene derivative, and a new oplopanone derivative have been found. The structures are elucidated mainly by spectroscopic methods together with some chemical transformations. From the chemotaxonomic viewpoint, the high concentration of very variable furanoeremophilanes may be important. The proposed differentiation into sections however can not be clearly correlated with the chemical constituents, though some taxonomic conclusions seem to be supported by the chemical evidence.  相似文献
