Longifolene is the common (or trivial) chemical name of a naturally occurring, oily liquid hydrocarbon found primarily in the high-boiling fraction of certain pine resins. The name is derived from that of a pine species from which the compound was isolated, Chemically, longifolene is a tricyclic sesquiterpene. This molecule is chiral, and the enantiomer commonly found in pines and other higher plants exhibits a positive optical rotation of +42.73°. The other enantiomer (optical rotation −42.73°) is found in small amounts in certain fungi and liverworts.

  • El longifolè és un compost orgànic volàtil líquid a temperatura ambient, de color blanc o groguenc clar. Químicament, aquest hidrocarbur es classifica com a sesquiterpè tricíclic. El longifolè és quiral, i el trobem en la forma dextrogira, (+)-Longifolè, principalment en plantes, mentre la forma levogira, (-)-Longifolè, es troba en alguns fongs. El seu nom prové de l'arbre on va ser descobert per primer cop, el Pinus longifolia (anomenat actualment , un pi de l'Himalaia). La seva estructura química va ser elucidada l'any 1953. (ca)
  • Longifolen ist der Trivialname eines natürlich vorkommenden Kohlenwasserstoffs. Longifolen ist ein chirales, rechtsdrehendes, tricyclisches Sesquiterpen. (de)
  • ロンギホレン (longifolene) は分子式 C15H24 で表されるセスキテルペン炭化水素の一種である。特異な三環性の骨格(ロンギホラン骨格)を持つ。化合物名は(Pinus longifolia、現在は Pinus roxburghii とされる)の精油から得られたことに由来する。 (ja)
  • 长叶烯(英語:Longifolene)是一种首先从松树树脂的高沸点馏分中分离出的油状碳氢化合物,长叶烯是这种天然产物的俗名,系统命名为(1R,2S,7S,9S)-3,3,7-三甲基-8-亚甲基-三环[5.4.0.02,9]十一碳烯。这个名字来自于提取出这种化合物的特定松树物种:西藏长叶松。 在化学上,长叶烯是一种三环倍半萜烯。这种分子具有手性,在其他松树等高等植物中存在的对映异构体旋光度为+42.73°。其他对映异构体(旋光度−42.73°)在某些特定的真菌和苔藓中少量存在。 长叶烯在有机合成中用于制备手性硼氢化试剂双长叶烯基硼烷。 长叶烯也是正山小种茶中最丰富的两种香味成分之一,因为制茶时要用松火进行熏蒸。 (zh)

  • Le longifolène est un composé chimique, un hydrocarbure huileux présent notamment dans la résine de certains pins. Il tire d'ailleurs son nom de l'espèce à partir de laquelle il a été isolé, Pinus longifolia (devenue Pinus roxburghii). Chimiquement, le longifolène est un sesquiterpène tricyclique qui possède deux énantiomères. Sa structure a été déterminée au début des années 1950. Le longifolène est utilisé en synthèse organique pour la préparation du dilongifolylborane, un agent hydroborant chiral. (fr)
