Essential oil composition of three Cryptocarya species from Malaysia

Abstract

Cryptocarya species are mainly distributed in Africa, Asia, Australia and South America, widely used in traditional medicines for the treatment of skin infections and diarrhea. The present investigation reports on the extraction by hydrodistillation and the chemical composition of three Cryptocarya species (Cryptocarya impressa, Cryptocarya infectoria, and Cryptocarya rugulosa) essential oils from Malaysia. The chemical composition of these essential oils was fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). A total of 51 components were identified in C. impressa, C. infectoria, and C. rugulosa essential oils representing 91.6, 91.4, and 83.0% of the total oil, respectively. The high percentages of α-cadinol (40.7%) and 1,10-di-epi-cubenol (13.4%) were found in C. impressa oil. β-Caryophyllene (25.4%) and bicyclogermacrene (15.2%) were predominate in C. infectoria oil. While in C. rugulosa oil, bicyclogermacrene (15.6%), δ-cadinene (13.8%), and α-copaene (12.3%) were predominate. To the best of our knowledge, there is no report on the essential oil composition of these three species.

The Genus Cryptocarya: A Review on Phytochemistry and Pharmacological Activities

“…[112] However, the leaf oils of two Malaysian species C. impressa and C. infectoria were dominated by two major compounds α-cadinol (40.7 %) and β-caryophyllene (25.4 %), respectively. [113] The obtained oils from C. massoy seem not to be affected by geographic collection since massoia lactones and benzyl benzoate were the principal compounds in its bark and heartwood oils, collected from Indonesia or Papua New Guinea. [114,115] Coconut laurels are referred to as endemic Australian Cryptocarya plants C. cocosoides, C. cunninghamii, C. bellendenkerana, and C. lividula.…”

“…Three highest percentage compounds in the leaf oils of three Vietnamese species C. concinna , C. impressa , and C. infectoria were caryophyllene oxide (21.2 %), bicyclogermacrene (18.7 %), and germacrene D (55.5 %), respectively [112] . However, the leaf oils of two Malaysian species C. impressa and C. infectoria were dominated by two major compounds α‐cadinol (40.7 %) and β‐caryophyllene (25.4 %), respectively [113] .

Sugarcane molasses essential oils: mesoporous silica nanoparticles as carriers to improve their slow-release activity and the study on their anti-inflammatory activitiesin vivo

“…The SMEOs extracted by MAHD were analyzed and identified by GC-MS by matching the retention index and retention time. There are few studies on the composition of SMEOs, and this study is based on the current literature on the constituents of plant essential oils 25,31,32 and a comparative analysis of literature studies related to the main components of the results of this study. [33][34][35] As shown in Table 1, 32 chemical components were identified in SMEOs, accounting for 94.92% of the total components.…”

Volatile components of Dillenia reticulata King (Dilleniaceae) essential oil and their cytotoxicity

“…The most predominant components were germacrene D (26.1%), β-caryophyllene (15.5%), α-pinene (13.3%), bicyclogermacrene (7.3%), and α-copaene (6.8%). The chemical differences among Dillenia species may depend on the extraction procedure, the season, the stage of development and the distinct habitat in which the plant was collected [14].…”
