Turmeric Oil: Composition, Extraction, Potential Health Benefits and Other Useful Applications

Abstract

The turmeric essential oil of Curcuma species has extensively more useful properties due to its rich phytochemical profile. The concentration of volatile chemical constituents varies according to their type of applied plant part (i.e., root, rhizome, leaves, and flower) for extraction and type of the adopted extraction method. Novel extraction and purification methods, subcritical CO2 , supercritical CO2 , pressurized liquid extraction, and molecular distillation are found to be more efficient for good recovery of this volatile oil, along with increased concentrations of specified compounds. Not only have the curcuminoid compounds had a broad potential in the field of pharmacology but also the turmeric oil is found to have great applicability in treating several diseases and disorders. Turmeric oil possesses good antioxidant, antimicrobial, anticancer, anti-hyperlipidemic anti-inflammatory, anti-diabetic, and hepato-protective properties. Apart from medicinal fields, this oil has also a great future in the cosmetics, pesticide, and food industries due to its rich chemical profile. The present review focuses on providing information about turmeric oil in terms of its physicochemical properties, chemical composition, and available traditional extraction techniques, as well as available novel extraction options, actual health benefits, and other useful applications. It is hoped that the reported information is helpful for further discovery in the area of food, pharmaceutical, and cosmeceutical applications.

Nanoemulsion-based plant essential oil formulations: in vitro evaluation of pesticidal activity against ectoparasites in poultry

“…Turmerone was found to be the major chemical compound in turmeric EO, comprising 68.46% of its composition ( Table 1 ). This is in line with other reports that have demonstrated turmerone as a major compound in turmeric EO, accounting for around 60% of its composition, possibly in the forms of ar -turmerone, α-turmerone, and β-turmerone ( Jayaprakasha et al, 2005 ; Liju et al, 2011 ; Jaiswal and Naik, 2021 ). However, variations in EO composition can occur due to factors such as geographical location, season, growth stage, and plant parts used.…”

In vitro and in vivo action of turmeric oil (Curcuma longa L.) against Argulus spp. in goldfish (Carassius auratus)

“…Our results were in agreement with previous studies by Pino et al (2018) , who reported that turmerone (58.9%) was the most represented class of volatiles from rhizomes grown in Amazonian Ecuador, including ar-turmerone (45.5%) and alpha-turmerone (13.4%). Similar results were performed by Jaiswal and Naik (2021) , Guimarães et al . (2020) , Intirach et al (2012) , and Devkota and Rajbhandari (2016) , whose data indicated that 58%, 50.05%, 49.21%, and 25.93% of turmerone were revealed as the major constituents, respectively.…”

“…The fresh rhizomes of turmeric were cut and chopped into small pieces. Then, turmeric essential oil extraction was carried out by the hydro-distillation method in Clevenger’s apparatus ( Hashimot o et al , 2016 ; Wesołowska et al , 2019 ; Jaiswal and Naik, 2021 ). The extracted essential oils were kept in a light-resistant, tightly sealed container and maintained at 4 ° C before use.…”

“…The total running time for a sample was about 50 minutes. The relative percentage of the essential oil constituents was evaluated from the total peak area of total ion chromatogram (TIC) by apparatus software ( Hashimoto et al , 2016 ; Wesołowska et al , 2019 ; Jaiswal and Naik, 2021 ).…”

“…It can be considered an agent with potential anti-tumour, anti-inflammatory, or antiviral effects. [136][137][138] Zedoary oil contains bioactive compounds such as elemene, curcumol, curdione, germacrone, and pinene, which contribute to its pharmacological activities. Studies have shown that Zedoary oil and β-elemene can inhibit cell cycle progression, leading to G2/M and G0/G1 cell cycle arrests.…”
