One New Compound from Fruiting Body of Cultivated Caterpillar Medicinal Mushroom, Cordyceps militaris (Ascomycetes), and Its Lipase Inhibitory Activity

Cordyceps militaris is a highly valued medicinal mushroom that has been traditionally used worldwide for its richness in metabolites with bioactive properties and pharmacological activities. This study investigated the chemical components of fruiting bodies of cultivated C. militaris. One new compound (compound 1) and seven known compounds (compounds 2-8) were isolated. The structure of the new metabolite was elucidated by nuclear magnetic resonance and high-resolution electrospray ionization mass spectrometry data. Compounds 1, 3, 4, and 5 exhibited lipase inhibitory activity at a 0.09 mg/mL concentration.
