Chemical composition of essential oil of Psidium cattleianum var. lucidum (Myrtaceae)

Abstract

The aim of this study was to investigate the essential oil composition of Psidium cattleianum var. lucidum from South Africa. The essential oils were extracted by hydrodistillation and the components were identified by gas chromatography coupled to mass spectrometry (GC-MS) to determine the chemical composition of the essential oil. A total of 53 chemical components were identified, accounting for 61% of the essential oil. The major component was caryophyllene oxide (12.43%), while other predominant constituents were identified as bicyclo(4.4.0)dec-l-ene (6.61%), 2,3-butanediol diacetate (4.84%) and patchoulene (4.73%). The presence of many terpenic and ester compounds is thought to contribute to the unique flavor of the P. cattleianum var. lucidum leaves.

Essential oil ofPsidium cattleianumleaves: Antioxidant and antifungal activity

“…Chalannavar et al (2013) studied the chemical composition of the EO of P. cattleianum of South Africa by hydrodistillation, the analysis revealed caryophyllene oxide as the major compound, and a predominance of non-oxygenated sesquiterpenes (36.78%), corroborating with our findings.…”

Characteristic Chemical Components and Aroma-active Compounds of the Essential Oils from <i>Ranunculus nipponicus</i> var. <i>submersus</i> Used in Japanese Traditional Food

“…Decyloxirane 56 and tetradecyloxirane 65 were detected in the Ranunculaceae family for the first time. These compounds have been identified as the characteristic components of only three families: Taxaceae 25 , Myrtaceae 26 , and Asteraceae 27, 28 .…”

Typification and nomenclatural notes on Psidium cattleyanum (Myrtaceae)

“…The fruits are rich in vitamin C (Lapčik & al., 2005;Biegelmeyer & al., 2011) and are consumed in natura or processed into jellies, jams, juices or ice creams (Santos & al., 2007). The leaves contain phenolic compounds with antioxidant, antimicrobial and anti-inflammatory activity, as has been demonstrated by numerous studies (Pino & al., 2001;Apel & al., 2006;Medina & al., 2011;Chalannavar & al., 2013). It is also (Uowolo & Denslow, 2008).…”
