Chemical Variability ofLitsea cubebaLeaf Oil from Vietnam

Chemotype of Litsea cubeba Essential Oil and Its Bioactivity

“…Several variations of the chemical composition of the leaf oil have been reported. The Chinese leaf oil consisted of a high percentage of α-cis-ocimene, β-phellandrene [14], citronellal [15] and citral [11]. In India, sabinene-rich [13] and linalool-rich [14] leaf oils were identified.…”

The Fungicidal Terpenoids and Essential Oil from Litsea cubeba in Tibet

“…The results showed that 33 compounds were present in this oil, namely limonol (44.2%), β-linalool (8.8%), 1,8-cineole (5.4%), elemicin (3.9%), methyleugenol (3.8%), esteragenol (2.8%), deoxygeraniol (2.6%), citronellal (2.5%), α-citral (2.1%), α-pinene (1.9%), myristicin (1.8%), β-Geraniol (1.6%), α-terpineol (1.4%), α-ocimene (1.3%), β-pinene (1.3%), terpinen-4-ol (0.8%), β-caryophyllene (0.7%), limonol acetate (0.7%), β-ocimene (0.6%), shikomol (0.6%), and the other thirteen minor compounds were 2-carene, 3-carene, m -cymene, p -cymene, γ-terpinene, 6,7-epoxy-linalool, rosenoxide, limonol formate, β-elemene, β-patchoulene, β-selinene, methylisoeugenol, β-caryophyllene oxide. The differences are limonol, β-linalool, 1,8-cineole, elemicin, and not citral, limonene, citronellal for the main components [1,2]. …”

“…The essential oil from the fruit contains 75% citral, but the essential oil from the leaves contains more 1,8-cineole than citral [1]. In fact the compositions were different due to their location and collection times [2]. The essential oil is widely used as a flavor enhancer in foods, cosmetics and cigarettes; as raw material for the manufacture of citral, vitamins A, E and K, ionone, methylionone, and perfumes; and as an antimicrobial and insecticidal agent [3], and the complex and molecular microcapsules of L. cubeba oil with β-cyclodextrin and derivatives were reported recently [4].…”

Antibacterial activity ofLitsea cubeba(Lauraceae, May Chang) and its effects on the biological response of common carpCyprinus carpiochallenged withAeromonas hydrophila

“…The major compound found in leaf essential oils was either 1,8‐cineole, sabinene, linalool or neral with a broad chemical variability among sampled regions (Bighelli et al . ; Wang and Liu ; Son et al . ).…”

“…A large variety of chemotypes of L. cubeba essential oils (EOs) has been described for different parts of the plant (root, stem, leaves, fruit, flowers) in different countries such as China, Taiwan, Vietnam, Tibet (Yang et al 2010;Si et al 2012;Li et al 2014). The major compound found in leaf essential oils was either 1,8-cineole, sabinene, linalool or neral with a broad chemical variability among sampled regions (Bighelli et al 2005;Wang and Liu 2010;Son et al 2014). In this regard, since the biological activities and therapeutic effects may vary based on the chemical composition of the plant material, we proposed to characterize the plant chemotype to be used in this study (Calo et al 2015).…”
