Abstract
Zingiberaceae plants are distributed in the tropical and subtropical regions of the world, being used in many famous medicinal materials. Meanwhile, some Zingiberaceae plants are important horticultural flowers because they are green all year round and have special aromas. To conduct an extensive investigation of the resources of Zingiberaceae plants, the volatile compounds of ten species of Zingiberaceae were extracted and analyzed by GC–MS, including Costus comosus var. bakeri (K.Schum.) Maas, Curcuma rubescens Roxb., Curcuma aeruginosa Roxb., Curcuma attenuata Wall., Hongfengshou, Hedychium coronarium Koeng, Zingiber zerumbet (L.) Smith, Hedychium brevicaule D. Fang, Alpinia oxyphylla Miq., and Alpinia pumila Hook.F. A total of 162 compounds were identified, and most of those identified were monoterpenes and sesquiterpenes. (E)-labda-8(17),12-diene-15,16-dial, n-hexadecanoic acid, 4-methoxy-6-phenethyl-2H-pyran-2-one, and L-β-pinene were found in high concentrations among the plants. These ten species of Zingiberaceae contained some of the same volatiles, but their contents were different. Pharmacological effects may be associated with the diversity of volatiles in these ten plants.
Highlights
Introduction published maps and institutional affilThe family Zingiberaceae comprises about 1500 species that are widely distributed in the tropical and subtropical regions of the world [1]
Zingiberaceae is a family of plants with high medicinal value, which are widely used for the treatment of various diseases: the rhizomes of Curcuma longa, Boesenbergia rotunda, Alpinia galanga, and Zingiber officinale are typically used to treat diarrhea, stomachache, and flatulence, for example [2,3,4]
Nphenethyl-2H-pyran-2-one is the main volatile of attenuata and but Hongfengshou
Summary
2),2), thethe volatile chemical constituents of ten Zingiberaceae plants were identified using the NIST database, and the values of the giberaceae plants were identified using the NIST 2014 database, and the values of the main main functional compounds from different plants were described. Functional compounds from different plants were described. Peaks indicated by red the arrows red arrows resent volatiles labeled in the figure. The main main volatile volatile compound compound of of C. attenuata,containing containing4-methoxy-64-methoxy(11.45%) (Table S1). Another plant of the same genus is C. attenuata, 6-phenethyl-2H-pyran-2-one (100%). As its main comphenethyl-2H-pyran-2-one (100%) and 5,6-dehydrokavain (19.34%) as its main compounds pounds. Cyclofenchene (33.83%), L-β-pinene (65.85%), and (E)(Table S1). Cyclofenchene (33.83%), L-β-pinene (65.85%), and (E)-labdalabda-8(17),12-diene-15,16-dial were detected as volatiles the mainofvolatiles of C.(Table aeru8(17),12-diene-15,16-dial (94.17%)(94.17%). Z. zerumbet volatile compounds atile compounds were identified, the main compound being myrtenal (21.42%). (Table were identified, the main compound being myrtenal (21.42%) (Table S1). The main volatile of H. coronarium was germacrone (100%) (Table S1). Volatile of H. coronarium was germacrone (100%) (Table S1)
