“…Compounds 1-4 are lanostane-type triterpenoids which have been frequently isolated from mushrooms, such as Ganoderma lucidum (Akihisa et al, 2005;Lee et al, 2010Lee et al, , 2011Tung et al, 2013) and Poria cocos (Kikuchi et al, 2011;Ukiya et al, 2002;Zhou et al, 2008). I. obliquus is also a proven and rich source of lanostane-type triterpenoids exemplified by the relatively abundant inotodiol (3) and 3b, 22-dihydroxyanosta-7, 9(11), 24-triene (4) (Handa et al, 2010;Liu et al, 2014).…”
