红豆杉科共有5属23种植物,除澳州红豆杉属的 AustrotaxusSpicata Campton 外,其余均产于北半球。美国科学家的研究表明,不仅大部分红豆杉科植物含有紫杉醇及其类似物,而且还有不少种属的新鲜针叶中的含量超过树皮中的含量。这不但扩大了植株的利用率,还有利于资源的保护和再生。我国的科学工作者几年来已查明境内的4种红豆杉种属及一个变种,即:中国红豆杉、东北红豆杉、云
Taxus families a total of 5 genera and 23 species of plants, in addition to the Australian taxus AustrotaxusSpicata Campton, the rest are produced in the northern hemisphere. The research of American scientists shows that not only most of Taxus plants contain paclitaxel and its analogues, but also many species of fresh needles contain more than the content of bark. This will not only increase the utilization rate of plants, but also help the conservation and regeneration of resources. In recent years, our scientific workers have identified 4 species of Taxus and one variety in the territory, namely: Chinese yew, Taxus cuspidatum,
