在这里，我们研究了长叶烯自氧化的反应机理及其产物的生物活性。长叶烯样品在 120 °C 或室温下自动氧化，并通过气相色谱法分析产物。在 120 °C 的自动氧化过程中，检测到长叶烯酮、降长叶内酯、异长叶酸、长叶酸和长叶烯羟基酮。在反应过程中，长叶烯通过形成长叶烯氧化物作为中间体而转化为其他自氧化产物。通过纸盘法在培养皿中检查长叶烯及其自氧化产物对日本地下白蚁（Reticulitermes speratusKolbe）的抗白蚁活性。长叶烯和自氧化产物表现出抗R。且所有自氧化产物均比长叶烯具有更强的杀白蚁和拒食活性。
Here, we investigated the reaction mechanism of longifolene autoxidation and the bioactivities of its products. A longifolene sample was autoxidized at 120 °C or room temperature, and the products were analyzed by gas chromatography. Longicamphenylone, norlongilactone, isolongifolic acid, longifolic acid, and longifolene–hydroxy ketone were detected as the products in the autoxidation at 120 °C. During the reaction, longifolene was converted into the other autoxidation products via the formation of longifolene oxide as an intermediate. Anti-termite activities of the longifolene and its autoxidation products were examined against a Japanese subterranean termite (Reticulitermes speratusKolbe) by paper disk methods in Petri dishes. Longifolene and the autoxidation products exhibited anti-R. speratusactivities, and all the autoxidation products had stronger termiticidal and antifeedant activities than longifolene.
