The mass spectra of phrymarolins, which were isolated from Phryma leptostachya L. as novel lignans, have been investigated. The most predominant fragmentation was the splitting of the acetal linkage. The fragment ions (m) and (n), at m/e 141 and m/e 99 respectively, are considered to be characteristic to the lignans. The accurate molecular weight measurements of important ions provided a further evidence for the structure of phrymarolin-I. 相似文献

Gelidocalamus stellatus Wen complex includes Gelidocalamus stellatus, Gauritus, Gmonophyllus, Gmultifolius and Gwugongshanensis, indicating the existence of some taxonomic disputes within this taxon. Based on 13 main phenotypic traits, in this paper, 13 populations of the complex are investigated and the results show that 1) All 13 characters have some changes between and within populations, of which the maximum is the height under branch with 276%, while the minimum is the ratio of length and width with 64%; 2) In the Jing Gang Mountain population (JGM), seven characters, such as the diameter at breast height, the node number, the height under branch, the leaf length, the leaf width, the ratio of leaf length and width, and numbers of each branch, are relatively stable among 4 different populations, and populations of Gstellatus Wen complex can be distinguished effectively by that seven characters, so it maybe have some worth for the clarification of the complex; 3) Besides that Jiu Yi Mountain population (JYM) and Xiao Long Gui population (XLG) share the same or similar traits with that of JGM, there have many remarkable differences between other populations, such the leaf in Lian Ping Country population (LPC) and Huang He Village population (HHV), the culm in Wu Gong Mountain population (WGM) and the numbers of each branch in Gan Zi Depression population (GZD) and Rong Jia Cavity population (RJC). With the observation of the culm sheath and the abaxial epidermis of leaves, the taxonomic position of some populations is discussed. Our results still indicate that Gmultifolius (Huang He Village population) and Gauritus may be null and void. Furthermore, we proposal Gwugongshanensis (Wu Gong Mountain population) and Gmonophyllus (Jiu Yi Mountain population) should be as a taxon under Gstellatus. 相似文献

巴西是全球生物多样性最丰富的地区,其竹类多样性也极为丰富。结合现存资料及野外调查,对巴西全境的竹类分布格局进行了讨论。巴西全国有原生竹亚科植物256种(含2亚种及3变种),北部地区草本竹类(莪莉竹族)最丰富,有61种,而东南部地区木本竹类(箣竹族)最丰富,有96种。偏穗竹属(Merostachys)(43种)和丘斯夸竹属(Chusquea)(45种)是最常见的属,并是最具潜在经济利用的竹类。属种的特有性分别高达32.4%和68.8%。特有属有11个,分别为莪莉竹族的双药莪利草竹属(Diandrolyra)、独焰草竹属(Eremitis)、小百瑞草竹属(Parianella)、赖茨草竹属(Reitzia)、苏克蕾草竹属(Sucrea)和箣竹族的南美梨藤竹属(Alvimia)、离枝竹属(Apoclada)、密穗竹属(Athroostachys)、卡姆巴珠瓦竹属(Cambajuva)、菲尔盖拉斯竹属(Filgueirasia)、无枝竹属(Glaziophyton)。 相似文献
