Citronellal or rhodinal ( C10 H18 O) is a mono terpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent.
Citronellal is a main isolate in distilled oils from the plants Cymbopogon (excepting C. citratus, culinary lemongrass), [3] lemon-scented gum, and lemon-scented teatree. The (S)-(−)- enantiomer of citronellal makes up to 80% of the oil from kaffir lime leaves and is the compound responsible for its characteristic aroma.
Citronellal has insect repellent properties, and research shows high repellent effectiveness against mosquitoes. [4] Another research shows that citronellal has strong antifungal qualities. [5]
