OBJECTIVE
To investigate the chemical constituents from the heartwood of Dalbergia cochinchinensis.
METHODS
Isolate and purify compounds by various column chromatographic methods. Spectral analysis were taken to identify the structures.
RESULTS
Elev- en compounds were isolated and identified as dibutyl terephthalate (1), medicarpin (2), pterostilbene (3), 6-hydroxy-2-(2-hydroxy-4- methoxyphenyl)-benzofuran (4), pterocarpol (5), butyl isobutyl phthalate (6), pterolinus B (7), methyl 4-hydroxybenzoate (8), ethyl 4- hydroxybenzoate (9),2-(2'-methoxy-4'-hydroxy)-aryl-3-methyl-6-hydroxy-benzofuran (10) and 6α-hydroxycyclonerolidol (11).
CONCLUSIONS
Compounds 1 and 6~10 are isolated from Dalbergia genus for the first time, and compounds 2, 4 and 11 are isolated from this plant for the first time.
