The invention relates to a new strain producing taxol and a taxol preparation method. The taxol is a diterpenoid alkaloid drug which is extracted from taxaceae plants and has a plurality of anti-tumor effects. Taxus, also known as yew, is a prehistoric plant with a history of 0.2 billion years and is a rare plant species with low growing speed; the biological characteristics of the taxus have high demand on the ecological environment; the natural renewal ability is poor, so the amount of the species is very limited, belonging to an endangered protection plant with limited resource, thus, scientists at home and abroad actively research and develop new taxol sources. The new strain for producing the taxol of the invention is the strain which is first separated from the bark of T.cuspidate Sieb.

产紫杉醇的新菌种及其选育和制备紫杉醇的方法，紫杉醇是从红豆杉属植物中提取出来的具有多种抗肿瘤疗效的二萜生物碱类药物，由于红豆杉，又名紫杉，是两亿年前的史前植物，是珍稀树种，生长速度缓慢，并且其生物学特性对生态环境要求较高，天然更新能力差，所以种群数量极为有限，属濒危保护植物，资源十分有限，因此，国内外学者都在积极地研究开发紫杉醇的新药源，本发明产紫杉醇的新菌种，所述的新菌种为从东北红豆杉T.cuspidate Sieb。

In order to disclose the adaptive strategies and capacity of Potaninia mongolica Maxim, acquired during its evolution history, the whole response system, which was composed of individual morphology plasticity response, organs anatomy structure response, physiological function response of anti-arid and anti-hotness, activities of protective enzymes response, endogenous hormone adjustment response, sexual reproduction strategies response of seeding, dispreading, sprouting and renewing, asexual reproduction strategies response of clonal growth patterns, clonal growth architectures, clonal growth architectures plasticity, heterogeneous resources utilization strategies, endogenous hormone distribution in clonal organs, foraging behavior, risk-spreading, and resource sharing, individual density allocation patterns response, niche differentiation response, species connection response, allelopathy response and biodiversity components response of the plant was profoundly explored in this paper.The studies come to at least four important results:(1) Taking the sensitive response and evading strategy to adapt to environment stress, Potaninia mongolica Maxim is a successful species has lived through the long-term evolution. Nevertheless, it is narrow climate and soil niche and characteristic of vegetation reproduction which has made the plant a rare and endangered species.
