OBJECTIVE
To study the chemical constituents of the dichloromethane extracted from pine needles of Cedrus deodara.
METHODS
Compounds were isolated and purified from the dichloromethane extract of pine needles by chromatography on silica gel and Sephadex LH-20. Their structures were identified on the basis of spectroscopic analysis and physicochemical property.
RESULTS
Nine compounds were isolated and purified. Their structures were identified as stigmasterol (1), oleanolic acid (2), parahydroxybenzaldehyde (3), beta-sitosterol (4), syringaresinol (5), daucosterol (6), p-hydroxybenzoic acid (7), gallicin (8) and gallic acid (9).
CONCLUSIONS
Compounds 1-3, 5 -9 are isolated from pine needles of this genus for the first time.
