“…Thirty-five lanostane triterpenoids and triterpene sugar esters including 13 new compounds ( 1 – 13 ) and twenty-two known analogues ( 14 – 35 ) were isolated from F. pinocola (Figure ). Twenty-two known lanostane triterpenoids were identified to be fomiroid A ( 14 ), 15α-hydroxy-3-oxolanosta-8,24-dien-21-oic acid ( 15 ), pinicolic acid E ( 16 ), ganosinoside A ( 17 ), fomitoside C ( 18 ), 15α-hydroxytrametenolic acid ( 19 ), fomitoside I ( 20 ), 3β-acetoxy-15α-hydroxylanosta-8,24-dien-21-oic acid ( 21 ), 3α-acetoxy-5α-lanosta-8,24-dien-21-oic acid ester β- d -glucoside ( 22 ), fomitoside H ( 23 ), piptolinic acid D ( 24 ), 16α-hydroxy-3-oxolanosta-7,9(11),24-trien-21-oic acid ( 25 ), 3β-hydroxy-16-oxolanosta-7,9(11),24-trien-21-oic acid ( 26 ), 3β- O -acetyl-16α-hydroxydehydrotrametenolic acid ( 27 ), 3β,16α-dihydroxylanosta-7,9(11),24-trien-21-oic acid ( 28 ), 3- epi -dehydropachymic acid ( 29 ), polyporenic acid C ( 30 ), 16α-hydroxy-24-methylene-3-oxolanost-8-en-21-oic acid ( 31 ), 16α-acetoxy-24-methylene-3-oxolanost-8-en-21-oic acid ( 32 ), 3- epi pachymic acid ( 33 ), palustrisoic acid H ( 34 ), and fomitoside K ( 35 ) by comparing their NMR spectroscopic data with compounds reported in the literature. The structure elucidation of 13 new compounds was shown as follows.…”
