Cell cloning Taiwan is fortunate in having a native Taxus species, so that the raw materials for experimentation are easily available. Furthermore, unlike the Pacific yew in which the highest concentrations of taxol are found in the bark, the Taiwan yew contains large amounts of taxol in its foliage. Thus harvesting reasonable quantities does not endanger the trees 'survival.
台灣幸運的擁有紅豆杉屬植物，實驗原料取得容易；不同於太平洋紫杉是以樹皮中含紫杉醇量最高，紅豆杉枝葉中就有高含量紅豆杉醇，適量取用，不致影響紅豆杉的生存，更是機不可失。
