After thermal degradation of linalool-chemotype leaf essential oil, degraded compounds including β-myrcene, cis-ocimene and trans-ocimene, were formed through the dehydroxylation of linalool; and ene cyclization also occurs to linalool and its dehydroxylated products to form the compounds such as limonene, terpinolene and α-terpinene. The optimal microencapsulation conditions of leaf essential oil microcapsules were at a leaf essential oil to the β-cyclodextrin ratio of 15:85 and with a solvent ratio (ethanol to water) of 1:5. The maximum yield of leaf essential oil microencapsulated with β-cyclodextrin was 96.5%. According to results from the accelerated dry-heat aging test, β-cyclodextrin was fairly stable at 105 °C, and microencapsulation with β-cyclodextrin can efficiently slow down the emission of linalool-chemotype C. osmophloeum leaf essential oil.beta cyclodextrin derivative; essential oil; linalool; vegetable oil; chemistry; Cinnamomum; drug stability; heat; microcapsule; plant leaf; Acyclic Monoterpenes; beta-Cyclodextrins; Capsules; Cinnamomum; Drug Stability; Hot Temperature; Oils, Volatile; Plant Leaves; Plant Oilsjournal article10.3390/molecules26020409334667652-s2.0-85100326528
