Plant volatile oil composition and preparation method thereof

The present invention relates to a plant volatile oil composition, comprising: at least one main particle, each main particle comprising a core layer comprising at least one plant volatile oil and at least one protective layer covering the core layer and comprising at least one phospholipid material and at least one surfactant; and a carrier in which the at least one main particle is dispersed. The invention also provides a preparation method of the plant volatile oil composition, which comprises the following steps: (1) mixing the at least one phospholipid material in a water phase solution to form a dispersion solution; (2) mixing the at least one plant volatile oil in the dispersion solution so that the at least one phospholipid material coats the at least one plant volatile oil to form at least one intermediate particle; (3) adding the at least one surfactant to attach to the at least one intermediate particle to form the at least one main particle; and (4) adding the carrier and dispersing the at least o
