Electroantennogram study showed that the female moths had stated response to main compositions of needle volatile of α-pinene,β-pinene, myrcene, limonene and β-phellandrene,β-phellandrene elicited the largest EAG response, and limonene was secondly.

松实小卷蛾雌蛾对思茅松针叶挥发性物质主要成分α-蒎烯、β-蒎烯、月桂烯、柠檬烯、β-水芹烯都表现出一定的触角电位反应，以β-水芹烯引起的松实小卷蛾触角电位反应最大，其次是柠檬烯。

Samples were subjected to high pressure ranging from 100 to 500 MPa. After high pressure treatments, the flavour compounds were extracted by Solid-Phase Microextraction. Analysis was carried out by Gas Chromatography-Mass Spectrometry. The key flavour compounds of orange juice were three alkenes (namely limonene, myrcene and α-pinene), two alcohols (linalool and α-terpineol), three aldehydes, one ketone and two esters (ethyl butyrate and 3-OH-ethyl hexanoate).

采用固相微萃取（Solid Phase Microextraction，SPME）方法对不同压力（100～500 MPa）超高压处理的鲜榨橙汁中的香气成分进行富集，并经气相色谱-质谱联用仪（Gas Chromatography-Mass Spectrometry，GC-MS）检测分析，橙汁中的主要香气成分有：3种烯（柠檬烯、月桂烯、α-蒎烯）；2种醇；3种醛；1种酮；2种酯（丁酸乙酯、3-OH-己酸乙酯），它们是构成橙汁的主要特征致香成分。
