Values are average of 15 replicates.
Weight of pure loaded monoterpenes (mg) = weight after loading (mg) − weight before loading (mg).
.
PD1: immobilization of blend of ketone monoterpenes (camphor, menthone, carvone, and fenchone) on paper discs.
PD2: immobilization of blend of alcohol monoterpenes (geraniol, thymol, and menthol) on paper discs.
PD3: immobilization of blend of alkene monoterpenes (limonene and camphene) on paper discs.
PD4: PD1 + citronella oil on paper discs.
PD5: PD2 + citronella oil on paper discs.
PD6: PD3 + citronella oil on paper discs.
PD7: immobilization of citronella oil on paper discs.
