3-carene

Investigation on Oleoresin Resource of 3-Carene in Yunnan Province

云南3-蒈烯资源的调查研究

The results would enrich the chemical utilization of 3-carene and establish the theoretical and practical foundation for the fine and high-valuable development of turpentine .

本研究成果为拓展3-蒈烯的化学利用途径、提高该类型松节油的精细利用价值奠定了理论和应用基础。

Fractions containing 56 ~ 72 % 3-carene were recovered by two-stage fractional distillation of Chinese wood and sulfate turpentines .

用两步法分馏中国木松节油和硫酸盐松节油回收到3-蒈烯含量达56～72%的几种馏分。

In three physiological states ,α - Pinene , and β - Phellandrene , 3-Carene are detected in different parts of P. orientalis , and their relative content are higher .

在3个生理状态下，侧柏的不同部位都检测到有α-蒎烯、β-水芹烯和3-蒈烯释放，且这3种组分的相对百分含量也较高。

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 .

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。

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 .

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。

The analysis of components of wood turpentine and sulfate turpentine shows that , besides a - 、β - pinene , there are 10.73 % and 8.01 % 3-carene sulfate turpentine in wood respectively .

本文研究了木松节油、硫酸盐松节油的组成。除α-蒎烯、β-蒎烯外，这两种松节油还分别含有10.73%和8.01%的3-蒈烯。

The analysis of resin contents showed that main monoterpenes were α - pinene , camphene , β - pinene , myrcene and limonene and some times there were 3-carene and α - terpine .

室内测定的结果表明油松松脂内的单萜组分有α-蒎烯、莰烯、β-蒎烯、香叶烯和柠檬烯，另外还含有少量3-蒈烯和α-萜品烯，但并不普遍；

By vaccum rectification , the fractions of α - pine with 96 . 3 % , β - pinene with 28 . 2 % and 3-carene with 45 . 0 % were obtained .

通过二次真空精馏，得到含α-蒎烯96.3%，β-蒎烯28.2%，3-蒈烯45.0%的三种主馏份，釜液中双戊烯含量较高。
