  • Species Diversity and Molecular Phylogeny of Macrolepiota and allied...

    Lepiotaceous fungi are in general saprotrophic forest floor dwellers. Some of them are excellent edible fungi while quite a few are poisonous. As this group of fungi act a key role in the evolution of basidiomycetes, they have long been the research interests for many mycologists.
      Under the financial support from National Natural Science Foundation of China (grants no. 30800004) and the Joi...

  • Higher Fungi Resources and Chemical Composition in Alpine and Sub-alpine Regi...

    On the basis of abundant field investigation, researchers YANG Zhu-Liang, LIU Pei-Gui, LIU Ji-Kai and their team collected 5300 specimens, more than 1290 strains, more than 700 mycorrhizal samples, more than 300 population genetics materials and chemical constituents samples of 30 species. On this basis, they carried out classification and systematics research for some important groups in alpin...

  • Anti-Cancer Constituents in the Herb Medicine-Shengma (Cimicifuga L)

    Professor QIU Ming-Hua and his group has isolated and identified 164 compounds, including 40 new constituents, 2 of which have novel skeleton, from six samples which are the rhizome of Cimicifuga foetida L and Cimicifuga yunnanensis H collected from Dali, Lijiang in Yunnan and Weining in Guizhou. Cooperating with Kunming Medical College, the group tested those compounds’ cytotoxicities against...

  • The Structure, Activity and New Drug Pre-Clinical Research of Monoterpene ind...

    Researcher Luo Xiao-Dong and his group have accumulated much experience about the extraction, separation and isolation, structural elucidation of monoterpene indole alkaloids in resent years, and discovered a series of novel alkaloids including 4 new skeletons published on Organic Letters in 2007, 2008 and 2009. Two of them were introduced by ‘Hot off the press’ of Natural Products Reports in...

  • Floristic study on the Seed Plants Yaoshan Mountain in Northeast Yunnan

    Yaoshan Mountain, the cordillera that Wumeng Mountains extends to the northeast, located in Qiaojia County of northeast Yunnan, which is on the edge of Sichuan, Yunnan and Guizhou along Jinshajiang valley. In terms of floristic regions, it belongs to the combining zone of Sino- Himalayan forest Sub-Kingdom and Sino-Japanese forest Sub-Kingdom, between Central China and Yunnan Plateau. Due to it...

  • Research Progress on Natural Tobacco Mosaic Virus (TMV) Inhibitors

    Voluminous research facts indicate that most secondary metabolites (Natural Products) of plants are of biological significance, the most representative function of which is ecological effect or chemical defense. Since 2002, Hao Xiao-Jiang’s research group of Kunming Institute of Botany, Chinese Academy of Sciences has been cooperating with Fang Rong-Xiang’s research group of Institute of Micr...

  • Warming climate may confuse plants


      Warm winters may shorten the growing season of plants that rely on cold weather cues, a study finds. Though previous research has shown that warming climate has accompanied early spring growth in many plant species, approximately a quarter of plants in temperate regions do not follow this pattern. Professor Jianchu Xu at the Kunming Institute of Botany, the Chinese Academy of Sciences publ...

  • The Wild Rice Whole Genome Frame Map is Completed by KIB Scientists

    In August 2010, the research team headed by GAO Li-Zhi in Kunming Institute of Botany, Chinese Academy of Sciences completed the de novo sequencing and assembling of wild rice (Oryza rufipogon) genome and has acquired the frame map covering the whole genome of wild rice. This is the first wild rice genome sequencing project carried out by Chinese scientistsindependently and is also the world’s...

  • Cytotoxic Triterpene Dilactones from the Stems of Kadsura ananosma

        Six new triterpene dilactones with a rare rearranged pentacyclic skeleton, longipedlactones K-P (1-6), and seven known analogues (7-13) were isolated from the stems of Kadsura ananosma. Compound I was found to possess a unique peroxide bridge between C-1 and C-9 in rings A and B. The structures of these new compounds were established on the basis of spectroscopic data analysis, especially o...
