The new meroterpenoid, chrodrimanin C (3), together with chrodrimanins A (2) and B (1) were isolated from okara (the insoluble residue of whole soybean) that had been fermented with strain YO-2 of Talaromyces sp. Their structures were elucidated by spectroscopic methods. The partial structures of 1 essential for exhibiting insecticidal activity were investigated by using a silkworm assay. The absolute configuration of 1 was also determined.
新型半萜类化合物氯德里马宁C（3）与氯德里马宁A（2）和B（1）一起，是从用拟青霉属菌株YO-2发酵的豆渣（全大豆的不溶性残渣）中分离得到的。它们的结构通过光谱方法得以阐明。利用家蚕试验研究了对表现出杀虫活性至关重要的1的部分结构。还确定了1的绝对构型。
