Neue guajanolide aus Lasthenia-arten

The investigation of two species of Lasthenia afforded two new guaianolides and a new bisabolone derivative, in addition to already known compounds. The presence of an eremophilenic acid in these plants is remarkable. The results are discussed chemotaxonomically, since the tribal position of this genus is still debated.     

Einige neue furanoeremophilane aus Senecio-Arten

The investigation of two varieties of the South African S. hypochoerideus affords, besides known compounds, six new furanoeremophilanes and a pimarene-derivative. By contrast, S. greyi has yielded two further new furanoeremophilanes and a new eremophilene. These structures are elucidated mainly by spectroscopic methods. Chemotaxonomic aspects are briefly discussed.     

Neue phloroglucin-derivate aus Leontonyx-arten sowie weitere verbindungen aus vertretern der tribus inuleae

The investigation of several South African species of the tribe Inuleae afforded in addition to known compounds 16 new constituents. From Leontonyx a group of 9 new phloroglucinol derivatives, from Stoebe species two new p-hydroxyacetophenone, two thymol and two coumaric acid derivatives and from Relhania a new euparine-derivative were isolated. The structures are elucidated mainly by spectroscopic methods. The chemotaxonomic aspects are discussed briefly. The phloroglucinol derivatives, which in part are derived from geraniol, seem to be especially characteristic.     

广东滩涂经济鱼类寄生吸虫──Ⅲ、单孔科、单脏科和八睾科吸虫的研究(复殖目)

Neue C10-säureamide,furanoeremophilane und andere inhaltsstoffe aus bolivianischen Senecio-arten

The investigation of seven Bolivian Senecio species afforded in addition to known compounds five new furanoeremophilanes, two C₁₀-amides, a new isoeugenol ester and the isomer of pterophorin. The structures are elucidated mainly by spectroscopic methods. While most of the new compounds are closely related to those isolated before from Senecio species, four of them are unusual. Another is a new type of a furanoeremophilane; its biogenesis however, can be explained easily from known types.     

中国三节叶蜂科分类研究I.扁胫三节叶蜂亚科一新属二新种(膜翅目)(英文)

东亚地区三节叶蜂科已经记载１０属约８０种,本文是中国三节叶蜂科系统分类研究之一,报道扁胫叶蜂亚科一新属：刺背叶蜂属Ｓｐｉｎａｒｇｅ,ｇｅｎ．ｎｏｖ．以四川刺背叶蜂Ｓｐｉｎａｒｇｅｓｉｃｈｕａｎｅｎｓｉｓ,ｓｐ．ｎｏｖ．为模式种,另外还包括刘氏刺背叶蜂Ｓｐｉｎａｒｇｅｌｉｕｉ,ｓｐ．ｎｏｖ．。新种的模式标本保存于中南林学院环境与资源系昆虫标本室。新属与中华三节叶蜂属ＳｉｎａｒｇｅＦｏｒｓｉｕｓ和似三节叶蜂属ＣｉｂｄｅｌａＫｏｎｏｗ近似,但新属中足胫节具亚端距,雄虫腹部第５背板具性沟和长突,与此二属以及扁胫叶蜂亚科已知各属均不同;此外,新属的胫节端距尖锐,后翅近基部无Ｃｕ－ａ脉,锯鞘背面具洼区,体金属兰色等与中华三节叶蜂属不同;雌虫触角仅等长于头宽,末端最宽,复眼小,内缘直,间距宽于眼高,后头膨大,前翅Ｒ＋Ｍ脉短于Ｓｃ脉等不同于似三节叶蜂属。此新属所包括的２新种的区别参见检索表。     

Neue sesquiterpene,triterpene, flavanone und andere aromatische verbindungen aus Flourensia heterolepis

The investigation of a further Flourensia species afforded in addition to already known compounds 12 new sesquiterpene acids isolated as their methyl esters, a new eudesmane diol, four lupane derivatives and two flavanones, two cinnamic acid derivatives, also isolated as methyl esters and a ketone. The structures are elucidated mainly by spectroscopic methods and by some chemical transformations. Several of the compounds isolated are more or less similar to those isolated from other Flourensia species; the considerable amounts of eudesmanes, however, are unusual. The overall picture of the genus is still relatively uniform. Close relationships to Helianthella are obvious, while to Helianthus, placed in the same subtribe, no clear relations are visible.

Neue furanoeremophilane und weitere inhaltsstoffe aus südafrikanischen Senecio-arten

The investigation of further 27 South African and a few other Senecio species afforded in addition to known compounds 18 new furanoeremophilanes, most of them being cacalol derivatives, two new lactones, a new eudesmane derivative and four acyl pyrrole derivatives. The structures are elucidated by spectroscopic methods mainly. The chemical results on more than 140 species now available indicate much of chemotaxonomic interest. Together with the chemical data on related genera, the taxonomic situation of the subtribe Senecioninae is discussed in connection with the proposed new classification. The chemical data are in good agreement with this new arrangement.     

Eremophilane derivatives from Senecio species

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.
