The occurrence of a series of new constituents which can be considered as Diels-Alder adducts of methyl vinyl ketone and ocimene (1–4), myrcene (9, 10) or β-far-nesene ( 11, 12), respectively, was reported. Furthermore, the structures of four isomeric cyclohexene derivatives could be established as adducts 21–24 of (E, Z)- and (E, E)-1,3,5-undecatrience and methyl vinyl ketone. Another series of constituents
了一系列新的组成部分,它们可以被认为是发生狄尔斯-阿德耳甲基乙烯基酮和罗勒烯(1-4),月桂烯(加合物9,10)或β-远nesene(11,12)分别是报告。此外,可以建立四种异构体环己烯衍生物的结构,作为(E,Z) -和(E,E)-1,3,5-不饱和度与甲基乙烯基酮的加合物21-24。具有降冰片烷骨架的另一系列成分分别代表甲基环戊二烯和1-辛烯-3-酮或甲基乙烯基酮的加合物25-32和33-40。依据阿尔德的内切-rule的内-异构体是占优势的天然以及在合成混合物。这些成分中的大多数也可以在绝对薰衣草以及新鲜制备的薰衣草花己烷提取物中(Lavandula officinalis CHAIX)进行鉴定。
