Seco-tremulane Sesquiterpenoids from the Cultures of the Medicinal Fungus Irpex lacteus HFG1102

Abstract Six previously undescribed 5,6-seco-tremulane analogues, together with two known ones, were isolated from the culture broth of the medicinal fungus Irpex lacteus HFG1102. The structures of the new compounds were elucidated via extensive spectroscopic methods, including NMR and HRMS spectroscopic analyses. Graphical Abstract
