Abstract:
Three new lanostanoid triterpenes named 3β,7β‐di‐ hydroxy‐11,15,23‐trioxo‐lanost‐8,16‐dien‐26‐oic acid (1), 3β,7β‐dihydroxy‐11,15,23‐trioxo‐lanost‐8,16‐dien‐26‐oic acid methyl ester (2), and 12β‐acetoxy‐3β,7β‐dihydroxy‐11,15,23‐trioxo‐lanost‐8,16‐dien‐26‐oic acid (3) were isolated from the fruit bodies of Ganoderma lucidum . They all show a Δ 16, 17 double bond unprecedented in such types of lanostanoid triterpenes possessing the side chain at C‐17. The complete NMR assignments for these compounds were carried out using 1 H, 13 C, DEPT, COSY, HSQC, HMBC, and ROESY NMR experiments. Copyright © 2007 John Wiley & Sons, Ltd.
