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).
CONCLUSION: Compounds 1-3, 5 -9 are isolated from pine needles of this genus for the first time.
