The present invention is related to a process for obtaining the (−)-13,14,15,16-tetranor-8a,12-labdanediol compound from the
Ageratina jocotepecana
plant, the process comprises the steps of a) obtaining an organic concentrated extract from the
Ageratina jocotepecana
shoot system; b) subjecting the organic concentrated extract to column chromatography in order to elute a fraction with the (−)-13,14,15,16-tetranor-8a,12-labdanediol compound; c) separating the eluted fractions comprising the (−)-13,14,15,16-tetranor-8a,12-labdanediol compound; and d) evaporating the organic solvent to yield the (−)-13,14,15,16-tetranor-8a,12-labdanediol compound in a solid form.
本发明涉及一种从Ageratina jocotepecana植物中获取(−)-13,14,15,16-四去甲基-8a,12-拉丹二醇化合物的方法,包括以下步骤:a)从Ageratina jocotepecana茎系统中提取有机浓缩物;b)将有机浓缩物经过柱层析以洗脱出含有(−)-13,14,15,16-四去甲基-8a,12-拉丹二醇化合物的分离物;c)分离含有(−)-13,14,15,16-四去甲基-8a,12-拉丹二醇化合物的洗脱分离物;d)蒸发有机溶剂以得到以固体形式存在的(−)-13,14,15,16-四去甲基-8a,12-拉丹二醇化合物。
