Essential Oil from the Fruits of Fissistigma bracteolatum and Fissistigma maclurei

Aims: The aim of this study was to isolate essential oils from the fruits of Fissistigma bracteolatum and Fissistigma maclurei (Annonaceae) and investigate the volatile constituents present they contained. Study Design: The study involves the hydrodisitillation of essential oils from the air-dried fruit samples of F. bracteolatum and F. maclurei and analysis of their chemical compositions by GC and GC-MS. Original Research Article Hung et al.; CSIJ, 17(3): xxx-xxx, 2016; Article no.CSIJ.29572 2 Place and Duration of Study: Fruits of F. bracteolatum and F. maclurei were collected from Pù Mát National Park, Nghệ An Province, Vietnam, in May 2014. Analysis of the oil samples was performed between June and August, 2014. Methodology: About 500 g of air-dried fruit samples was shredded and their oils were obtained by separate hydrodistillation for 4 h at normal pressure, according to the Vietnamese Pharmacopoeia specifications. The chemical constituents of the distilled oils were analyzed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). Results: The main constituents in the fruit of F. bracteolatum are α-pinene (15.5%) and δ-cadinene (11.0%), with significant amounts of β-caryophyllene (8.0%) and germacrene D (7.0%) while spathulenol (21.2%) and β-cubebene (10.6%) are the quantitatively significant compounds of F. maclurei fruit. Conclusion: The present oil compositions of fruit of F. bracteolatum and F. maclurei were reported for the first for these species and the results were found to differ from previous studies on other parts of the plants.
