“…Patchoulol was the main oxygenated component in the EO extracted from patchouli leaves, but the relative amounts differed for the two isolation methods; it was the most abundant oxygenated component of the MAHD extract (26.32 %), whereas the HD extracts contained 27.78 %. Taking into account the comparison studies of extraction method between MAHD and HD by other researchers on different plants, it seems the constituents and their concentrations obtained by both of method were almost similar [15,28,29]. All these results have proved that microwave greatly accelerated the extraction process, but without causing significant affect in the EO composition.…”

“…Ultrasound assisted extraction, pressurized liquid extraction, supercritical fluid extraction and microwave assisted extraction have drawn researchers' attention and prompted them to develop methods relatively more advantageous than the conventional (CHEMAT, 2013). The method using ultrasound has been studied by several researchers in order to increase the quality of essential oil and decrease the extraction time and the costs (ROMDHANE & GOURDON, 2002;PÉREZ-SERRADILHA et al, 2007;CRAVOTTO et al, 2008;PORTO & DECORTI, 2009;WANG et al, 2010;DJOUAHRI et al, 2013;FILLY et al, 2014).…”

“…Considering that oil quality is related to its chemical composition, the choice of a suitable extraction method is extremely important. The method employed should not influence negatively the composition, avoiding the decomposition of the interest compounds in order to maintain the quality of the final product (BAKKALI et al, 2008;DJOUAHRI et al, 2013).…”

Essential oils are substances originated from plants in general. These compounds are well known to have a high biological activity, specially the antioxidant and antimicrobial. Several extraction techniques are employed to obtain these substances. However, the majority of these techniques require a long extraction time. In this sense, innovative and alternative extraction techniques, such as ultrasound, have recently been the target of studies. In view of the small amount of publications using ultrasonic pretreatment, this review aimed to congregate current relevant information on ultrasound-assisted extraction of essential oils. In this sense, theoretical aspects, such as the main factors that influence the performance of this technique as well as the advantages and disadvantages of the use of ultrasound as an environmental friendly alternative technique to improve the extraction of essential oil in comparison to traditional methods, are shown. Considering the available studies in the literature on essential oil extraction using ultrasonic pretreatment, low frequencies ranged from 20 to 50kWz and times ranged from 20 to 40min were used. The use of ultrasonic pretreatment represents a time reduction to near 70% in relation to the conventional hydrodistillation. Also, these conditions enabled a growth in the extraction of bioactive compounds and consequently improving the antioxidant and antimicrobial activities of essential oils.

“…Extraction of essential oils is a critical step because, depending on the conditions used for extraction (e.g., heating, amount of plant material, atmosphere composition, time for extraction), the composition of essential oils could change with impact on their antioxidant and antimicrobial activities (DJOUAHRI et al, 2013). Hydrodistillation (HD) is one of the most used methods for essential oil extraction, and it is recommended in official compendia of quality control of aromatic plants (Brazilian Pharmacopeia, 2010;IAL, 2004).…”

Oxygen introduction during extraction and the improvement of antioxidant activity of essential oils of basil, lemon and lemongrass

et al. 2017

Essential oil extraction is commonly carried out by using the hydrodistillation method, which is described in official compendia of food quality control and medicinal plants. Despite the widespread use of this method, few studies have evaluated the effect of the atmosphere change during extraction on the composition and antioxidant activity of essentials oils. Therefore, a study of oxygen introduction influence during the extraction of essential oils from basil, lemongrass and lemon by hydrodistillation was performed. Total amount of oxygenated compounds (e.g., linalool, camphor, α-terpineol, neral, geranial, eugenol and α-muurolol) increased for all essential oils extracted under oxygen flow. Antioxidant activity evaluated by using the ORAC method significantly increased (P<0.0001) with oxygen from 618 to 906, 355 to 613 and 72 to 262µmol Trolox g-1 oil for basil, lemongrass and lemon, respectively. Therefore, the simple modification proposed could be considered a suitable alternative to obtain essential oils with higher antioxidant activity.
