茧蜂亚科已知有123个属(Quicke,1987),其中窄腹茧蜂属Angustibracon Quicke是Quicke(1987)根据分布在印度的1个种Bracon leptogaster Cameron重新组合为1个新属而建立,迄今已定名种仅此1种。我们整理广西茧蜂标本时,鉴定出该属1新种。这是本属种类在我国分布的首次报道,现将该属属征和新种形态记述如下。新种模式标本存湖南农学院昆虫标本室。  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

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

Eumorphia sericea and E. prostata contained several new furanosesquiterpenes and a new triterpene aldehyde. Structures were elucidated mainly by spectroscopic methods and by some chemical reactions. Structures of three compounds however could not be established with certainty and are partially based on biogenetic considerations. Gymnopentzia bifurcata also contained known furanosesquiterpenes. The number of South African genera from the tribe Anthemideae, where these furanosesquiterpenes are characteristic, has now increased to eight. The importance of these observations for the botanical position of these genera is still not clear.  相似文献

The investigation of two South African Helichrysum species afforded in addition to known compounds two new chalcone derivatives, four related dihydrochalcones,5,7,8-trimethoxyflavone and 5-methoxy-7,8-methylenedioxyflavone. The structures are elucidated by spectroscopic methods and some chemical transformations. The chemotaxonomic situation in the large genus Helichrysum is discussed, in the light of these results.  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 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.  相似文献
