From the leaves of Diospyros decandra , three compounds including a sesterterpen 2Z‐3,7,11,15,19‐pentamethyleicos‐2‐en‐1‐ol ( 1 ), astragalin ( 2 ), beta‐sitosterol ( 3 ) and from the barks daucosterol ( 4 ), bacosine ( 5 ) were isolated. Their structures have been elucidated by IR, MS and NMR spectroscopic methods. All of the above compounds have been isolated for the first time from this plant. This is the first report about the chemical constitutents of Diospyros decandra in Vietnam.
