An alcoholic extract of Dalbergia sympathetica , on column chromatography, yielded a compound which analyzed for C 6 H 11 NO 3 (M + 145). The IR spectrum of the compound showed the presence of carbonyl and hydroxyl groups. PMR, 13 C and DEPT NMR spectral studies of the compound showed the presence of one N ‐methyl, two methine and two methylene groups. A quaternary carbon signal at δ 172.88 ppm was assigned to C‐2 carbonyl of the compound. From all the above observations and also from the HMQC 2D NMR spectrum, the compound was identified as 3, 6‐dihydroxy‐ N ‐methyl‐2‐piperidone. This is the first report of the natural occurrence of this compound from plant sources. Copyright © 2004 John Wiley & Sons, Ltd.
