First Chemical Investigation of Korean Wild Mushroom, Amanita hemibapha subsp. javanica and the Identification of Anti-Helicobacter pylori Compounds.

ABSTRACT: Amanita hemibapha subsp. javanica (Amanitaceae) is an edible Korean wild mushroom. A. hemibapha subsp. javanica is often confused with A. subjunquillea, known as the East Asian death cap, which is potentially fatal when ingested. This study aimed to conduct the first chemical investigation of A. hemibapha subsp. javanica, which resulted in the isolation of seven fatty acid derivatives (1-7) and three steroids (8-10) from the MeOH extract of its fruiting bodies, and their structures were determined by comparing their NMR spectroscopic data with those previously reported, along with the data from LC/MS. Compound 1 was reported previously without the identification of its absolute configuration; its structure, including the absolute configuration was confirmed for the first time, in this stud
