Taxol, a diterpenoid secondary product from the bark of yew species, has been approved an efficient anti-cancer drug for breast cancer and some other tumor diseases.

紫杉醇是从红豆杉属植物中提取的二萜类次生代谢产物，已被证明具有治疗乳腺癌及多种肿瘤疾病的作用。

Paclitaxel, mostly described by the tradename Taxol, is a diterpenoid that can be found in the bark and needles of different Taxus trees.

紫杉醇，通常商品名为Taxol紫杉醇，是一种二萜类化合物，存在于紫杉属树木的树皮和针叶中。

Evergreen trees or shrubs; sometimes classified as member of the family Taxaceae.

常绿树木或灌丛；有时被看作是紫杉科的一属。

Paclitaxel was first isolated from Taxus brevifolia Taxaceae in the sixties from last century, and its derivative Taxotere1 was clinically introduced 30 years later for the treatment of mainly ovarian and breast cancers.

紫杉醇是在其衍生物taxotere1在临床上用于治疗卵巢癌和乳癌后30年于上个世纪六十年代首次从紫杉属红豆杉科中分离得到的。

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。

Mairei is a variation of Taxaceae Taxus in china, and it containsPaclitaxel, which is a kind of anticarcinogen, in its branch, bark, needle, root andpulp. In order to production oftaxol in callus cultures of Taxus chinensis var.

mairei，为红豆杉科红豆杉属在中国的1个变种，其枝、皮、叶、根和果肉中均含有抗癌药物紫杉醇(Paclitaxel，商品名Taxol)。

Paclitaxel is a natural product isolated from the Pacific yew tree, Taxus brevifolia.
