Being low in calories and high in proteins, fibre, vitamins and minerals, a large number of wild mushrooms are valuable for food, and, thus, the consumption of wild edible mushrooms, a popular delicacy in many countries, has been increasing very rapidly.
Mushroom poisoning cases have been frequently reported in East Asia or even in other parts of the world. Some of the toxins in the mushroo...
Mycorrhizae play a vital role in the life cycle and evolutionary history of orchids. The genera Cypripedium and Paphiopedilum, both belonging to the subfamily Cypripedioideae of the Orchidaceae, are very well known as slipper orchids in horticultural science. However, due to the environment disruption and over collection of the orchids, all species in the two genera are listed in the Appendix o...
Predicting global change is a scientific question as well as a general concern of human society. To accurately predict global change, we must master the climate changes in geologic history time and history period. The reconstruction of paleclimate can not only provide important basic information for predicting global change, but also provide an opportunity to discuss the interrelationship betwe...
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...
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...
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...
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...
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...
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...
