Supercritical carbon dioxide extraction of turmeric oil from Curcuma longa Linn and purification of turmerones

QUALITY PARAMETERS OF Curcuma longa L. EXTRACTS BY SUPERCRITICAL FLUID EXTRACTION (SFE) AND ULTRASONIC ASSISTED EXTRACTION (UAE)

“…This probably due to extraction can be done without the usage of modifier as the carbon dioxide used in the SFE itself will be able to extract out all compounds at supercritical point whereby the temperature and pressure set has reaches the critical point. This was also supported by previous research done by Chang et al [5], which reported that the use of supercritical carbon dioxide was possible without the addition of co-solvents. Carbon dioxide have been widely used as extracting solvent for SFE as it is non-toxic, available abundantly, non-explosive, can be removed easily from the final extract without leaving a solvent residue [7] and the most important is the low viscosity of carbon dioxide enables it to penetrate into the matrix of the analyte to reach the material being extracted and extract out the material selectively [7].…”

“…The volume of modifier added to the dried sample might be too little for the modifier to aid in the extraction process. Chang et al [5] supported this claimed by stated that larger solvent volume can dissolve target components more effectively and thus increase the extraction yield.…”

“…SFE has advantages such as environmental friendly as it does not use toxic organic solvent, able to select thermally labile compounds under mild conditions and has a shorter time. Other than SFE, UAE is also one of the alternative methods to replace conventional extraction processes [5]. In most previous literatures, UAE has been known as a tool that assists in the extraction of medicinal compounds or different vegetal materials [6].…”

Quantitative determination of eight components in rhizome (Jianghuang) and tuberous root (Yujin) of Curcuma longa using pressurized liquid extraction and gas chromatography–mass spectrometry

“…2. Eight characteristic peaks were identified in Jianghuang and Yujin by comparing the mass spectra with literature [21][22][23][24][25][26][27] or standards, which were ␤-caryophyllene, arcurcumene, zingiberene, ␤-bisabolene, ␤-sesquiphellandrene, ar-turmerone, ␣-turmerone and ␤-turmerone, respectively. The MS data are summarized in Table 1.…”

Optimization of ionic liquid based ultrasonic assisted extraction of antioxidant compounds from Curcuma longa L. using response surface methodology

“…Conventional methods of extracting curcuminoids turmeric generally involve large amount of organic solvents, and can be timeconsuming, low extraction efficiency, not environmentally friendly. Recently environment friendly techniques, such as microwave assisted extraction (Aoki et al, 2005;Mandal et al, 2008;Wakte et al, 2011), ultrasonic assisted extraction (UAE) Wakte et al, 2011), and supercritical fluid (SCF) (Chang et al, 2006;Zabihi et al, 2014) have been reported. Among these methods, UAE has been widely used to extract phytochemicals from many matrixes as an efficient, energy-saving, environmental friendly extraction technique.…”
