“…Structures of the new compounds (1−16) were further confirmed by analysis of 2D NMR spectroscopic data. The known compounds were identified by comparison of the spectroscopic data with those reported in the literature; these are ganorbiformin C (17), 7 astraodoric acid A ( 18), 8 astraodoric acid B ( 19), 8 20, 9 astraodoric acid C ( 21), 8 ganorbiformin E ( 22), 7 ganoderic acid V (23), 7,10 ganorbiformin D (24), 7 25, 11 ganoderic acid Mb (26), 12 ganorbiformin F (27), 7 ganoderic acid Md (28), 12 7-Omethylganoderic acid O (29), 13 ganoderic acid Mi (30), 14 ganorbiformin G (31), 7 32, 15 ganoderic acid TR (33), 16,17 34, 15 35, 18 ganoderic acid R (36), 19 ganoderic acid T (37), 19 38, 20 ganoderic acid S (39), 19 ganoderic acid X (40), 10,21 41, 22 and ganorbiformin A (42). 7 Compound 1 was isolated as a colorless solid, and the molecular formula was determined to be C 32 H 46 O 6 by HRESIMS.…”
