Abstract (300 words maximum)
Turmeric (Curcuma longa) is a plant belonging to the ginger family Zingiberaceae. Native to South and Southeast Asia, the golden-yellow spice has been cultivated for dyes, spices, and a variety of health benefits since ancient civilization. Turmerones are responsible for turmeric’s vibrant color, anti-inflammatory and antioxidant properties. With these medicinal properties, turmeric has been added into supplement capsules, immunity shots, and pain relief topical solutions. Turmeric is also widely used in traditional herbal medicine to help with diseases such as asthma and arthritis. We are interested in identifying and evaluating turmerone compounds in ground turmeric, turmeric supplement capsules, and turmeric rhizomes. Ethanol was selected as the extracting solvent. Sonification for 10 minutes was used to improve extraction. Extracted solutions from various samples have been analyzed using gas chromatography-mass spectroscopy (GCMS, Agilent-QP2010). Ar-tumerone, nonaromatic tumerone), and curlone have been identified as the three major turmerone compounds across all samples. They were eluted at 16.01 minutes, 16.23 minutes, and 17.71 minutes, respectively. Nonaromatic turmerone is relatively more abundant in ground turmeric, whereas aromatic turmerone has a higher abundance in turmeric supplement capsules.
