In a climatically controlled chamber (28±1℃, L16:D8), E. splendens was planted in pots containing mixed vermiculite and perlite without Cu. At about 220 d after seeding, plants (around 65 cm in height) were used to collect their volatile using SPME. Eleven chemicals were identified using GC-MS, p-pinene, D-limonene, elsholtzia ketone, dehydro elsholtzia ketone,γ-elemene, humulene, caryophyllene, a-caryophyllene, and three sesquiterpenes. The most abundant volatiles were caryophyllene and y-elemene, followed by humulene and a-caryophyllene.
