Talarodiolide, a New 12-Membered Macrodiolide, and GC/MS Investigation of Culture Filtrate and Mycelial Extracts of Talaromyces pinophilus.


ABSTRACT: Talarodiolide, a new 12-membered macrodiolide, was isolated and characterized from the culture filtrate of strain LT6 of Talaromyces pinophilus. The structure of (Z)-4,10-dimethyl-1,7-dioxa-cyclododeca-3,9-diene-2,8-dione was assigned essentially based on NMR and MS data. Furthermore, several known compounds were isolated and identified in the crude extract of the culture filtrate and mycelium of this strain. EI mass spectrum at 70 eV of all isolated metabolites was acquired and compiled in a custom GC/MS library to be employed to detect metabolites in the crude extracts.
