    • An improved method for isolating taxol and certain clinically important analogues of taxol from a crude extract of a naturally occurring Taxus species comprising treating the extract by reverse phase liquid chromatography on an adsorbent, causing the taxol and the taxol analogues to be adsorbed on the adsorbent, and recovering taxol and the natural analogues of taxol from the adsorbent by elution with an elutant. The compounds thus isolated in pure form are taxol, taxol-7-xyloside, 10-deacetyltaxol, 10-deacetyltaxol-7-xyloside, cephalomannine, cephalomannine-7-xyloside, 10-deacetylcephalomannine-7-xyloside, baccatin III, 10-deacetylbaccatin III, baccatin VI, brevitaxane A, and taxiflorine.
    • 一种用于从天然发生的紫杉属植物的粗提物中分离紫杉醇和紫杉醇的某些临床重要类似物的改进方法,包括通过反相液相色谱法在吸附剂上处理提取物,使紫杉醇和紫杉酚类似物吸附在吸附剂上, 并用洗脱液洗脱从吸附剂中回收紫杉醇和紫杉醇的天然类似物。 如此分离的化合物为紫杉醇,紫杉醇7-木糖苷,10-脱乙酰紫杉醇,10-脱乙酰基紫杉醇-γ-木糖苷,头孢麻黄碱,头孢麻黄碱-7-木糖苷,10-脱乙酰基头麻甘露7-木糖苷,浆果赤霉素III,10-脱乙酰基浆果赤霉素 III,浆果赤霉素VI,红霉素A和紫杉醇。

    • An improved method for isolating taxol and certain clinically important analogues of taxol from a crude extract of a naturally occuring Taxus species comprising treating the extract by reverse phase liquid chromatography on an adsorbent, causing the taxol and the taxol analogues to be absorbed on the adsorbent, and recovering taxol and the natural analogues of taxol from the adsorbent by elution with an elutant. The compounds thus isolated in pure form are taxol, taxol-7- xyloside, 10-deacetyltaxol, 10-deacetyltaxol-7-xyloside, cephalomannine, cephalomannine-7-xyloside, 10-deacetylcephalomannine-7-xyloside, baccatin III, 10-deacetylbaccatin III, baccatin VI, brevitaxane A, and taxiflorine.

    • An improved method for isolating certain clinically important taxane derivatives from the crude extract of a naturally occurring Taxus species comprising treating the extract by reverse phase liquid chromatography on an adsorbent; causing the taxane derivatives to be adsorbed on the adsorbent; and recovering the taxane derivatives from the adsorbent by elution with an elutant. The taxane derivatives thus isolated in pure form are taxol, taxol-7-xyloside, 10-deacetyitaxol, 10-deacetyltaxol-7-xyloside, cephalomannine, cephalomannine-7-xyloside, 10-deactylcephalomannine-7-xyloside, baccatin III, 10-deacetylbaccatin III, baccatin VI, and brevitaxane A.
