Abstract

The essential oil of Schinus terebinthifolius fruits was reinvestigated using GC and GC-MS techniques. Apart from several known compounds three sesquiterpene hydrocarbons with a carbon skeleton exhibiting the rare spiro(cyclopropane) moiety could be isolated by a combination of column chromatography and GLC. Structure assignments were carried out by NMR spectroscopy. These natural products are 9-spiro(cyclopropa)-4,4,8-trimethyl-2-methylenbicyclo[4.3.0]non-1(6)-ene (terebanene), 9-spiro(cyclopropa)-2,4,4,8-tetramethylbicyclo[4.3.0]nona-1,5-diene (teredenene), and (6R*,8R*)-9-spiro(cyclopropa)-2,4,4,8-tetramethylbicyclo[4.3.0]non-1-ene (terebinthene).

摘要

利用 GC 和 GC-MS 技术重新研究了 Schinus terebinthifolius 果实的精油。除了几种已知的化合物外，通过柱层析和 GLC 的组合，还可以分离出三种具有罕见螺环（环丙烷）部分的倍半萜烃。通过 NMR 光谱进行结构鉴定。这些天然产物是 9-螺（环丙烷）-4,4,8-三甲基-2-亚甲基双环[4.3.0]壬-1(6)-烯（terebanene）、9-螺（环丙烷）-2,4,4,8-四甲基双环[4.3.0]壬-1,5-二烯（teredenene）和（6R*,8R*）-9-螺（环丙烷）-2,4,4,8-四甲基双环[4.3.0]壬-1-烯（terebinthene）。
