彩娱乐登陆网址 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, 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, 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.

"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.

半年后再去检查被确诊为原发性，真正被癌症盯上常先生顿时慌了，但这时候说什么都晚了……

这次，刘亦菲在接受采访时被问到这个问题，她没有回避，也没有生气，彩娱乐官网而是大方地承认了自己的“溜肩”特点。她表示，每个人都有自己的特点，美不应该被单一定义。她觉得自己的肩膀挺舒服的，而且穿衣服也很好看，这就足够了！

The findings have been published in the scientific journal PhytoKeys.  ■彩娱乐登陆网址
