Abstract:

Objective: To study the chemical constituents of Pinus kesiya R. pinecone. Methods: The constituents were isolated and purified by extracting with system solution and using column chromatography with silica gel, RP-18, Sephadex LH-20 and MPLC.Their structures were identified by the spectral analysis. Results: Six compounds were isolated and identified as pinoresinol(1), matairesinol (2), cedrusin (3), dihydrodehydrodiconiferyl alcohol (4), 4',5,7-trihydroxyflavanonol-3'-O-β-D- glucopyranoside(5), and 3,4-dihydroxybenzoic acid(6). Conclusion: These 6 compounds were obtained from P. kesiya for the first time.

Key words: Pinus kesiya R., pinecone, chemical constituents, lignans
