Abstract:

Objective:To study the chemical constituents from pinecone of Pinus kesiya R. Methods:The constituents were
extracted with 95% ethanol,isolated and purified by column chromatography with silica gel,Sephadex LH-20 and recrystallization. Then their structures were elucidated on the basis of spectroscopic data. Results:Five compounds were isolated and identified as 15-hydroxydehydroabietic acid(1),15- hydroxylabd- 8(17)- en- 19- oic acid(2),junicedric acid(3),β- sitosterol(4),and daucosterol(5). Conclusion:This is the first report on the compounds 2-4 from Pinus kesiya R.

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