摘要

Stem bark of Dalbergia lanceolaria was subjected to methanolic extraction and extensive phytochemical separation. The process yielded four known compounds namely Jateorin (1), Columbin (2), β-sitosterol (3), and Lupeol (4). The compounds were identified using nuclear magnetic resonance spectral data namely 1H NMR, 13C NMR, 1H-1H COSY, HMBC, and DEPT-135 and verified by comparing the data with previous literature. All four compounds are being reported for the first time from the species D. lanceolaria. Furthermore, two furanoditerpenes namely Jateorin and Columbin are reported for the first time from the genus Dalbergia. This may lead to potential identification of a new chemotaxonomic marker for this genus.
