Abstract

New nine insecticidal antibiotics designated yaequinolones were isolated from the culture broth of the fungal strain Penicillium sp. FKI-2140 by solvent extraction, centrifugal partition chromatography and HPLC. Yaequinolones showed growth inhibitory activity against brine shrimp (Artemia salina). Among them, yaequinolone F has the most potent activity with MIC value of 0.19 microg/ml.

摘要

通过溶剂萃取、离心分配色谱法和高效液相色谱法，从真菌菌株青霉菌FKI - 2140的培养液中分离出九种新的杀虫抗生素，即yaequinolones。Yaequinolones对卤虫（Artemia salina）表现出生长抑制活性。其中，yaequinolone F活性最强，最低抑菌浓度（MIC）值为0.19微克/毫升。
