“…We decided to use an ultrasound-assisted (UA) method to ensure a rapid and an efficient pretreatment with NADES. In these last times, microwave-assisted pretreatment has mainly been chosen for the extraction of essential oils with NADES as co-solvents ( Stanojević et al., 2021 ; Xu et al., 2021 ; Zhao et al., 2019b ), while, as far as we know, UA pretreatment was used only for the extraction of essential oil of Perilla frutescens leaves ( Chen et al., 2022 ). In our work, we decided to pretreat the suspension of nutmeg fruits and 40% NADES at 50 °C for 30 min.…”

“…Despite a large number of researches on the use of NADES as extraction solvents of natural compounds ( Cunha and Fernandes, 2018 ; Fernandez et al., 2018 ; Liu et al., 2018 ), as far as we know, little has been reported about the use of NADES in the preparation of essential oils ( Stanojević et al., 2021 ; Xu et al., 2021 ; Yu et al., 2018 ; Zhao et al., 2019a ).…”

“…The total ion chromatograms of RCL and RHCL volatile oils are shown in Figure 1 . By comparing the obtained mass spectra data with the NIST MS spectra database and previous literature data [ 6 , 33 , 37 , 38 , 39 ], we totally identified 45 compounds, mainly including monoterpenes, sesquiterpenes, and other types. Their chemical structures are shown in Figure 2 , and the compounds’ information and their peak area ratio in all tested samples are listed in Table 1 .…”

The root tuber and rhizome of Curcuma longa L., abbreviated, respectively, as RCL and RHCL, are used as different medicines in China. In this work, volatile oils were extracted from RCL and RHCL. Then, gas chromatography–mass spectrometry (GC–MS) was used for RCL and RHCL volatile oils analysis, and 45 compounds were identified. The dominant constituents both in volatile oils of RCL and RHCL were turmerone, (−)-zingiberene, and β-turmerone, which covered more than 60% of the total area. The chromatographic fingerprint similarities between RCL and RHCL were not less than 0.943, indicating that their main chemical compositions were similar. However, there were also some compounds that were varied in RCL and RHCL. Based on the peak area ratio of 45 compounds, the RCL and RHCL samples were separated into principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). Then, 20 compounds with a variable importance for the projection (VIP) value of more than 1 were the high potential contributors for RCL and RHCL differences. Furthermore, ferric ion-reducing antioxidant power (FRAP) assay results demonstrated that the volatile oils of RCL and RHCL had antioxidant activities. This study provided the material basis for the research of volatile components in RCL and RHCL and contributed to their further pharmacological research and quality control.

“…Unfortunately, adoption of this technique to satisfy the growing demand for essential oil production is insufficient because it’s hindered by longer extraction times: 7 h according to Variyana et al [ 7 ] and Widayat et al [ 8 ] and low yield of extraction [ 9 , 10 ] : 0.6–5.5% [ 1 , 11 – 14 ] over 18% as prescribed by Sankara et al [ 15 ] for aromatics plants. Point is, the recalcitrant and endogenous oil body structure of the aromatic plant tissue that inhibits the migration of the extractant and the release of intracellular metabolites [ 2 , 4 , 9 , 10 , 16 ]. Inevitably, it follows back a large quantity of residues that could still contain essential oil in addition of being abundant in phenolic compounds, oligomers and flavonoid glycosides with various biologically active principles [ 17 – 20 ].…”

The solid waste of Curcuma longa rhizomes generated after its cold juice process making is mostly unused and discarded even though they can contain essential oil. Conventional techniques such as hydrodistillation can be used to extract essential oil, but this generally results in low essential oil yield and inefficient extraction time. Solid-state fermentation as a pretreatment of distillation could improve the yield of essential oil. In this study, we evaluated the effect of solid state fermentation on the yield of extraction of Curcuma longa solid wastes essential oil. The solid-state fermentation was carried out naturally without any addition of inoculum and the extraction was performed by hydrodistillation. Under experimental conditions at room temperature ( ) with a moisture content of 44% and anaerobically in the dark, the treatment of 7 days of solid state fermentation followed by 2 h of hydrodistillation provided the highest yield of 1.21% as compared to non-fermented of 0.35% and of 0.96% relative to the raw plant material representing an increase of 71% and 21% respectively. A set of experiments was then carried out by a Doehlert matrix to optimize the yield of extraction. Two independent variables, namely the distillation time and the fermentation time, were studied. Under optimal experimental conditions of 10 days and 4 h, a yield of 1.96% was obtained validating the statistical model. The solid state fermentation applied before the hydrodistillation step has been successful and proves its potential to improve the efficiency of essential oil extraction. Graphical Abstract
