Analysis of the Essential Oils from Five VietnameseLitseaSpecies (Lauraceae)

Litsea cubeba leaf essential oil from Vietnam: chemical diversity and its impacts on antibacterial activity

“…Other studies have reported different compositions containing either neral 32·9%, sabinene 14·2%, linalool 9·5%, limonene 9·2% from Hue province (central region of Vietnam) (Son et al . ), or a mixture of 1,8‐cineole (13·97%), γ ‐elemene (8·27%), caryophyllene (8·04%), linalool (6·94%), limonene (6·78%) from samples collected in China (Wang and Liu ). Altitude has been described as one of the most important factors affecting the composition and yield of EOs (Melito et al .…”

“…However, different chemotypes of L. cubeba EOs have been reported depending on the plant part and the origin (Ho et al 2010;Saikia et al 2013;Li et al 2014b). For instance, neral was found to be the main compound in fruits and roots; b-terpinene and 1,8-cineole in flowers, b-phellandrene and terpinen-4-ol in stems and the major compound found in leaves was either 1,8-cineole, sabinene, linalool or neral (Ho et al 2010;Son et al 2014).…”

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

“…Our finding confirmed the result obtained for the single sample of Bavi (north region). In another study, the main compounds of leaf EO of L. cubeba from Hue province-Vietnam (central region) were different with: (Z)-citral (=neral) 32Á9%, sabinene 14Á2%, linalool 9Á5%, limonene 9Á2%, terpinen-4-ol 4Á0% (Son et al 2014). The main components of L. cubeba leaf samples from China showed another pattern containing cineole, c-elemene, caryophyllene, linalool (6Á94%), limonene (Wang and Liu 2010).…”

“…; Wang and Liu ; Son et al . ). 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 .…”

“…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).…”
