摘要: 用气相色谱-质谱-计算机联用仪鉴定了华山松皮油树脂中12种成分。对贵州省平坝县华山松良种场华山松种源试验林中13个种源树皮含油树脂样品分析,观察到单萜总量和倍半萜总量,包括α-蒎烯、双戊烯和蛇麻烯等成分的含量与其种源产地纬度有极明显的地理变异规律。云贵高原种源为以双戊烯为主的单萜类型;秦岭—大巴山地种源是以蛇麻烯为主的倍半萜类型。

Abstract: Cortical turpentine compositions of 69 individuals from 10 Pinus armandi seed sources originating throughout the range were analysed in a provenance test forest by a gas chromatography-mass spectra-computer combined instrument. The results showed that the turpentine contained in the farks of P. armandi were mainly monoterpene and sesquiterpene. The content of diterpene was detected as minor constituent. The significant geographic vatiations between total amounts of monoterpene and sesquiterpene, including a-pinene dipentaene and hop alkene, and the latitutes of its provenance origin were observed. The trees from the Yunnan-Guizhou plateau seed provenance contained mainly monoterpene. On the contrary, the sesquiterpene was mainly contained in Qinling-Daba mountain seed provenance.
