澳门六合彩-金牛版 New firmoss species discovered in SW China with potentials to treat Alzheimer
BEIJING, Sept. 10 (Xinhua) -- Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) under the Chinese Academy of Sciences (CAS) have discovered a new firmoss species in southwest China澳门六合彩-金牛版, an extract of which has been proved to be effective in the treatment of Alzheimer's disease.
The new species, which is later named Huperzia crassifolia, was discovered during a medical plant inventory research in southwest China's Guizhou Province, according to a CAS press release.
Liu Hongmei, an XTBG associate researcher, a member of the research team said that Huperzia, also commonly known as firmoss, has about 25 species and mainly grows in temperate and boreal climatic zones.
The newly-discovered Huperzia crassifolia is a terrestrial firmoss. It resembles other Huperzia species' gross morphology澳门六合彩-金牛版, but can be easily distinguished by its thicker texture and round-lanceolate pinnae, Liu told Xinhua on Monday.
According to Liu, Huperzine A, a substance found in firmoss plants has been proved to be very effective in the treatment of Alzheimer's disease.
The new species is only known to grow in Guizhou, Hubei, Hunan and Chongqing in China, and it often roots in the humus rich soils in broad leaf forests at an altitude from 1,100 to 1,900 meters above sea level with a very small population at each locality, said Liu.

那场比赛，狐狸真的按着曼城在摩擦，尤其是下半场，只能说狐狸运气不好，曼城运气好！而咱们之前聊曼城的时候，也经常说的一个话题就是，面对现在的曼城，只需要切断德布劳内和其他人的链接就可以了，只需要中场紧逼延缓曼城的进攻就好了！而曼城作为强队，要打的主动，喜欢进攻，进攻阵型就容易压上！那作为他的对手，只需要有高效的反击就好了，一脚干净利索的身后球，就可以威胁到曼城！
"If people know its medicinal value, Huperzia crassifolia may be in danger of being over-collected. We tentatively propose its conservation status as Endangered (EN) according to the International Union for Conservation of Nature (IUCN) categories and criteria," said Liu.
The findings have been published in the scientific journal PhytoKeys. ■澳门六合彩-金牛版
