Abstract
Two methoxylated isoflavones were isolated form the roots of Dalbergia horrida. These compounds show great promise as pharmaceutical agents. The ^1^H and ^13^C NMR spectra of the compounds were completely assigned by using a combination of 2D NMR experiments which included ^1^H–^1^H COSY, HMQC and HMBC studies.

1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
