中文摘要：

目的：对思茅松松塔的化学成分进行初步研究。方法：采用溶剂法提取思茅松松塔的化学成分，运用正相硅胶、反相RP-18、Sephadex LH-20柱色谱和中压液相色谱等方法进行分离纯化，利用波谱数据鉴定化合物的结构。结果：从中分离鉴定了6个化合物，分别为：松脂醇（1），罗汉松树脂酚（2），（7S，8R）-3’，4，9，9’-四羟基-3-甲氧基-7，8-二氢苯并呋喃-1’-丙醇基新木脂素（3），dihydrodehydrodiconiferyl alcohol（4），二氢槲皮素-3’-O-β-D-吡喃葡萄糖苷（5），3，4-二羟基苯甲酸（6）。结论：6个化合物均首次从该植物中分离得到。

英文摘要：

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.
