为了研究‘班×印2号’、‘班×印6号’、‘班×印7号’、‘班×印8号’4个不同杂交种质白胡椒精油的化学成分。以印尼大叶种和班尼约尔1号为杂交亲本的4个杂交种质：‘班×印2号’、‘班×印6号’、‘班×印7号’、‘班×印8号’为原料，通过GC-MS对这4个杂交种质白胡椒精油的化学成分进行分析。结果表明：（1）胡椒品种不同对胡椒精油化学成分的种类与含量都有显著影响。（2）3-蒈烯、柠檬烯、石竹烯、α-石竹烯、β-蒎烯、β-月桂烯、δ-榄香烯和α-蒎烯8种烯类物质是这4个杂交种质白胡椒精油中含量较多的化学成分。其中，‘班×印8号’杂交种质白胡椒精油中3种特有成分是(+)-环苜蓿烯、白菖油烯和β-萜品烯；‘班×印2号’杂交种质白胡椒精油、‘班×印6号’杂交种质白胡椒精油与‘班×印7号’杂交种质白胡椒精油中单独共有的3种成分是α-萜品烯、β-侧柏烯和α-蛇床烯。不同杂交种质白胡椒精油化学成分的种类与含量差异显著。

The essential oil composition of four hybrid germplasms of white pepper(Piper nigrum L.) were analysis by GC-MS method. The results showed that different hybrid germplasms had great influence on the constituents and their contents of the white pepper essential oil. The main constituents of four kinds of white pepper essential oil were 3-carene, limonene, caryophyllene, α- caryophyllene, β-pinene,β-Myrcene , δ-elemene and α -pinene. (+)-Cyclosativene , calarene andβ-terpinene were detected only in white pepper essential oil of hybrid No.8;α-terpinene, β –thujene and α-selinene were detected only in white pepper essential oil of hybrid No. 2,6 and 7.
