Leaf Essential Oil Composition ofCitrus japonicafrom Nepal

Germacra‐1(10),5‐dien‐4α‐ol in Fortunella sp. leaf oils

“…crassifolia oil from California (α‐terpineol, 21.9%; octyl acetate, 9.6% and geraniol, 8.9%); F . marg arita oil from China (linalool, 26.5%; methyl N‐methyl anthranilate, 11.1%); Citrus japonica (syn: Fortunella japonica ) oil from Nepal (linalool, 35.1%; geraniol 12.7%; eugenol, 14.8%) . In contrast, they resembled leaf oils of F .…”

“…California (α-terpineol, 21.9%; octyl acetate, 9.6% and geraniol, 8.9%) [2] ; F. margarita oil from China (linalool, 26.5%; methyl N-methyl anthranilate, 11.1%) [3] ; Citrus japonica (syn: Fortunella japonica) oil from Nepal (linalool, 35.1%; geraniol 12.7%; eugenol, 14.8%). [4] In contrast, they resembled leaf oils of F. margarita from Colombia containing mostly γ-eudesmol (19.0%), β-elemol (18.8%) and β-eudesmol (12.4%) [6] and leaf oils of F. japonica, F. margarita and F. crassifolia from Greece, which contained germacrene D (9.0-16.4%) and β-elemol (8.7-13.2%) as main components.

“…Leaf oil composition of Citrus japonica (syn: F . japonica ) from Nepal was dominated by oxygenated monoterpenes, linalool (35.1%), geraniol (12.7%), geranial (7.9 %), nerol (5.3 %), as well as two phenyl propanoids, eugenol (14.8%) and (Z)‐asarone (5.0 %) . In contrast, the following two papers reported essential oils dominated by sesquiterpenes.…”

Integrated Analysis by GC(RI), GC-MS and 13C NMR of Fortunella Japonica Leaf Volatiles Obtained by Hydrodistillation, Microwave- assisted Hydrodistillation and Hydrolate Extraction

“…Concerning F. japonica (Thunb.) Swing., the main components of the leaf oil from Nepal were the monoterpenes linalool (35.1%) and geraniol (12.7%), beside eugenol (14.8%) [8], while leaf oil from Thailand contained mainly β-pinene (47.4%), limonene (10.2%) and linalool (9.8%) [9]. In contrast, the main components of EO isolated from leaves of F. japonica grown in Vietnam were elemol (17.7%), β-eudesmol (16.6%) and epi-bicyclosesquiphellandrene (16.6%) [10].…”

“…Special attention will be brought to the identification of components (particularly sesquiterpenols) by using a combination of chromatographic and spectroscopic techniques. [8] and the leaf oil from Thailand whose composition is dominated by -pinene [9].…”
