A liquid chromatography–thermospray ionisation–mass spectrometry guided isolation of a new sesquiterpene aryl ester from Armillaria novae-zelandiae
Abstract
A liquid chromatography–thermospray ionisation–mass spectrometry guided fractionation of the mycelial extract of Armillaria novae-zelandiae (strain CBS 432.72) led to the isolation of a new protoilludane sesquiterpene aryl ester, 6′-chloro-10α-hydroxymelleolide (9). The antibacterial and antifungal activity of 9 was determined.
