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.

缅甸芒果姜 (Curcuma amada Roxb.) 中挥发性有机化合物的表征


姜黄（Cucuma amada Roxb）。 （姜科），俗称芒果姜，因其根茎及叶部有与芒果相似的香气。根茎已广泛用于食品工业和替代药物，用于治疗多种内科疾病，如咳嗽、支气管炎、消化不良、绞痛、食欲不振、打嗝和便秘。新鲜C. amada根茎中挥发性成分的组成尚未详细报道。本研究旨在筛选和表征来自缅甸的三种C. amada （ZO45、ZO89 和 ZO114）和一种C. longa （ZO138）新鲜根茎中的挥发性有机化合物（VOC）的组成。通过顶空固相微萃取（HS-SPME）结合气相色谱-飞行时间质谱（GC-TOF-MS）进行分析。结果，从提取的 373 个质谱中初步鉴定出了 122 种 VOC。以下化合物是十种最丰富和最广泛存在的化合物： ar-姜黄酮、α-姜烯、α-檀香烯、( E )-γ-atlantone、古巴烯、β-红没药烯、teresantalol、β-倍半芹烯、反式-α-香柠檬素、γ-姜黄烯。青蒿素（ Arturmerone）的强度，即倍半萜烯，主要存在于龙加精油中（高达 15.5-27.5%），与龙加种质 ZO138 相比， C. amada种质 ZO89 中的倍半萜烯含量显着更高（15.707 ± 5.78 ^a ）。 (0.300± ^0.08b )。在两个C. amada种质 ZO45 和 ZO89 中未检测到顺式-α-香柠檬烯。 该研究揭示了C. amada和C. longa新鲜根茎中已识别挥发性有机化合物的物种间差异。
