The most effective components were citronellal
and nerol against all pathogens used in our study.
On the other hand, antifungal activities have not been associated with the concentrations of citronellal
officinalis (diploid, 2n = 32 chromosomes, no or only few hairs on the leaf blades, typical lemon-like fragrance caused by citronellal

Some of the fragrances are known to have a repellent effect on insects, e.g., citronellal
, which is often used in candles or insect repellent lotions.
The citronella (CIT), in neat liquid form (citronellal
, with a molecular weight of 154.3), was purchased from Sigma-Aldrich Co.
The aroma fraction from the orange pulp (sample 7) contained less limonene and more citronellal
, terpinen-4-ol, and [alpha]-terpineol than the orange peel oil.
As indicated by changes in intracellular chemistry, each of three odorants--carvone (spearmint or carroway seeds), citronellal
(citrus), and limonene (lime)--activated a different chimeric receptor.
(2006) who also reported the insect killing activity of eucalyptus oils against Varroa which has been owed to the constituents such as citronellyl acetate, eucamalol, 1, 8-cineole, p-cymene, citronellal
, limonene and citro-nellol.
