title: Micromelosides A-D, four new coumarins from the stem bark of Micromelum falcatum.
abstract: Four new coumarins, micromelosides A-D, together with four known coumarins were isolated from the stem bark of Micromelum falcatum. The complete assignments of the 1H and 13C NMR chemical shifts for these new compounds were achieved by means of 1D and 2D NMR techniques, including 1H-1H COSY, HSQC, HMBC and NOE difference.
