Curcuma amada Roxb. (Zingiberaceae), commonly known as mango ginger because its rhizome and foliar parts have a similar aroma to mango. The rhizome has been widely used in food industries and alternative medicines to treat a variety of internal diseases such as cough, bronchitis, indigestion, colic, loss of appetite, hiccups, and constipation. The composition of the volatile constituents in a fresh rhizome of C. amada is not reported in detail. The present study aimed to screen and characterize the composition of volatile organic compound (VOC) in a fresh rhizome of three C. amada (ZO45, ZO89, and ZO114) and one C. longa (ZO138) accessions originated from Myanmar. The analysis was carried out by means of headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-time-of-flight-mass spectrometry (GC-TOF-MS). As a result, 122 VOCs were tentatively identified from the extracted 373 mass spectra. The following compounds were the ten most highly abundant and broadly present ones: ar -turmerone, α-zingiberene, α-santalene, ( E )-γ-atlantone, cuparene, β-bisabolene, teresantalol, β-sesquiphellandrene, trans -α-bergamotene, γ-curcumene. The intensity of ar- turmerone, the sesquiterpene which is mainly characterized in C. longa essential oil (up to 15.5-27.5%), was significantly higher in C. amada accession ZO89 (15.707 ± 5.78 a ) compared to C. longa accession ZO138 (0.300 ± 0.08 b ). Cis -α-bergamotene was not detected in two C. amada accessions ZO45 and ZO89. The study revealed between-species variation regarding identified VOCs in the fresh rhizome of C. amada and C. longa .
