Abstract
Alcoholic extraction of Dalbergia sympathetica leaves yielded N‐methyl‐trans‐4‐hydroxy‐L‐proline and not 3,6‐dihydroxy‐N‐methyl‐2‐piperidone, as previously reported. This is shown by the identity of the ^1^H and ^13^C NMR data of the isolated compound with those of N‐methyl‐trans‐4‐hydroxy‐L‐proline. Copyright © 2006 John Wiley & Sons, Ltd.
