【摘要】 德国Ｗ．Ｌａｎｇｅ在研究不同地区来源的欧洲赤松松脂的化学组成时，曾按△~３－蒈烯含量不同，将它们分成中欧和南欧地区二类。本文研究俄罗斯境内的欧洲赤松松脂的组成，发现它与同纬度的中欧地区欧洲赤松松脂一样，含有较高数量的△~３－蒈烯。同时发现，在中国境内的欧洲赤松的２个变种──樟子松和长白松松脂中△~３－蒈烯含量也随纬度不同而有明显差别。更多还原

【Abstract】 P. sylvestris was classified into two groups-central Europe and south Europe based on amounts of △￣3-carene in oleoresins of trees from different latitudes by W. Lange. This paper studied the chemical compositions of oleoresin from P. sylvestris grown in Russia. It contains high amounts of △￣3-carene like that in central Europe at the same latitude. At the same time, oleoresins of two varieties of P.sylvestris P. mongolica and P. sylvestriformis grown in China were studied which showed also obvious difference in amounts of △￣3-carene with different latitudes.更多还原
