摘要：研究不同采脂季节湿地松单株产脂力和松脂化学组成。结果表明:湿地松松节油富含β-蒎烯(年均33.63％);采脂季节与松脂含油率以及松节油中α-蒎烯含量,β-蒎烯含量,α-蒎烯/β-蒎烯值之间相关密切,其相关系数分别为0.79、-0.49、0.62、-0.56;松脂中松节油含量的增加主要来自松脂中β-蒎烯绝对量的增长,与α-蒎烯含量无关;随着采脂季节的变化,β-蒎烯含量递增。
Variations in chemical compositions of oleoresin from Pinus elliottii Engelm. in different tapping seasons were studied. The results show that the turpentine from P. elliottii Engelm. contains a rather great percentage of β-pinene (in average 33. 63%). The content of turpentine in gum, as well as the contents of α-pinene,β-pinene and the ratio of a-pinene/β-pinene in turpentine is closely related to the season of oleo-resin production. The correlation coefficient of them are 0. 79,- 0. 49, 0. 62,-0. 56 respectively. The increase of turpentine content in gum is mainly due to the increase of β-pinene but not related with the α-pinene content. The β-pinene content grows up along with the progressing of the season of oleoresin production.
