The present study reports the isolation of two eudesmanolide type sesquiterpenoid lactones, viz. alantolactone and isoalantolactone, from the roots of Inula racemosa Hook L. and their chemicaltransformations using various reagents. All the compounds isolated and synthesized were assessed for their in vitro antifungal potential against Dreschlera oryzae, Fusarium moniliforme, and Alternaria triticina
本研究报告了两种eudesmanolide 型倍半萜内酯的分离,即。alantolactone 和 isoalantolactone,来自 Inula racemosa Hook L. 的根,并使用各种试剂进行化学转化。使用孢子萌发抑制方法评估了所有分离和合成的化合物对稻瘟病菌、念珠镰刀菌和小麦链格孢的体外抗真菌潜力。为了了解倍半萜内酯的结构与其抗真菌功能的关系,研究了结构活性关系。发现异戊内酯及其衍生物与丙戊内酯及其衍生物相比毒性更大。在不同的合成化合物中,溴仿衍生物的效果最好,而甲氧基衍生物的效果最差。
