Effect of three extraction methods on the volatile component of Illicium verum Hook. f. analyzed by GC-MS

Abstract

The physical properties and chemical components of three oil samples extracted from Illicium verum Hook. f. by steam distillation (SD), solvent extraction (SE) and supercritical fluid extraction ( SFE) were compared with one another and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS). The quality parameters of star anise essential oil from SFE were close to that of those came from SD and SE. Although the extraction yield of star anise by SFE (9.2 %) was close to the value from SE (9.3%), it was yet higher than that came from SD (8.2%). For sensory evaluation, however, three oils were significantly different. The odor and taste of the products from SFE and SE were generally more natural and vivid than that came from distilled oil. The volatile compound revealed that significant differences of the composition existed in the distilled oil and the oleoresins prepared by SFE and SE.

Illicium verum: A review on its botany, traditional use, chemistry and pharmacology

“…However, it is necessary to choose the right extraction conditions (extraction time and pressure) to avoid the co-extraction of undesired compounds of high molecular which are not responsible for flavor together with volatile oil (Reverchon, 1992). Wang et al (2007b) compared the physical properties and the composition profiles of the extractions from star anise by three separation procedures, SD, SE and SFE, coupled with GC-MS. The three extracts were characterized by different colour and smell, with total anethole content from 75.0% to 77.3%.…”

Optimization of High-Concentration Trans-Anethole Production Through Hydrodistillation of Star Anise

“…Star anise (Illicium verum Hook) is an aromatic vegetable cultivated in Asian countries, especially in China and Vietnam (Asif et al, 2016;Wang et al 2007). Its fruit contains volatile oil, resin, fat, tannin, pectin, and mucilage, whereas its seeds contain little volatile oil, resin, and a large amount of non-volatile oil (Chempakam & Balaji, 2008;Li et al, 2010;Wang et al, 2011).…”

Its aroma is due especially to its high essential oil content, 2.5-3.5% (w/w) in fresh fruit and 8-9% in dried fruit (Wang et al, 2007). The essential oil, which is found in the pericarp but not in the seed, consists mainly of trans-anethole: 70-94% (Asif et al, 2016;Bhadra et al, 2011;Chouksey, Upmanyu, & Pawar, 2013;Wang et al, 2007).…”
