El '''limonè''' és un [[hidrocarbur]], classificat com un [[terpè]] [[Compostos cíclics|cíclic]]. És una molècula [[quiral]] i té dos [[enantiòmers]], el R-Limonè (fa l'olor característica de la llimona i és el que contenen llimones i taronges) i el S-Limonè (fa l'olor de pi).<ref>{{Ref-llibre|cognom = Sell|nom = Charles S.|títol = Chemistry and the Sense of Smell|url = https://books.google.es/books?id=Mpc6AwAAQBAJ&pg=PT335&lpg=PT335&dq=limonene+odour+error&source=bl&ots=OndO2oq1Aj&sig=FrC40vNuEylddaRfz6sSZjeQ3lk&hl=ca&sa=X&ved=0ahUKEwiOuJPU-LrKAhXIWxoKHVvLDskQ6AEINTAD#v=onepage&q=limonene%20odour%20error&f=false|edició = |llengua = anglès|data = 26 de març de 2014|editorial = John Wiley & Sons|lloc = |pàgines = 480|isbn = 1118522966}}</ref> Aquest [[Compost químic|compost]] és present a la pell dels [[cítric|cítrics]], com la [[llimona]] o la [[taronja]], però també a [[Teixit (biologia)|teixit]]s de moltes altres [[plantes]].<ref>{{ref-web|url=http://www.pherobase.com/database/floral-compounds/floral-taxa-compounds-detail-limonene.php|títol=Plantes que contenen limonè|editor=pherobase}}{{en}}</ref>
