Characteristic Scent from the Tahitian Liverwort, Cyathodium foetidissimum.

The volatile components of the Tahitian liverwort Cyathodium foetidissimum was analyzed using headspace solid phase micro-extraction (SPME) and GC-MS. Three volatile components, 4-methoxystyrene (24.4%), 3,4-dimethoxystyrene (28.

Volatile Compounds from the Different Organs of Houttuynia cordata and Litsea cubeba (L. citriodora).

The volatile compounds obtained from the different organs of Houttuynia cordata (Saururaceae) and Litsea cubeba (Lauraceae) were analyzed by Gas Chromatography/Mass Spectrometry (GC/MS), Headspace Solid Phase Micro Extraction-Gas Chromatography/Mass Spectrometry (HS-SPME-GC/MS), and GC/olfactometry (GC/O). The major component of all parts of H. cordata is assigned as 4-tridecanone.

Comparative Study on Volatile Compounds of Alpinia japonica and Elettaria cardamomum.

The volatile compounds obtained from the ether extracts, headspace gases and steam distillates of Alpinia japonica and Elettaria cardamomum were analyzed by GC/MS. Both species were rich sources of naturally rare fenchane-type monoterpenoids, fenchene, fenchone, fenchyl alcohol and its acetate, together with 1,8-cineole. The distributions of volatile sesquiterpenoids were very poor in both species.

Odor-Active Components of Luo Han Guo (Siraitia grosvenorii).

The volatile components -of the dried fruit of Luo Han Guo (Siraitia grosvenorii Swingle) belonging to the family Cucurbitaeae were analyzed by AROMASCOPE® technique using MonoTrap® DCC 18 as an absorbent. A total of 124 volatile components were identified from the headspace aroma solvent extract. The major components were ethanol, butan-l-ol, pentanal, 2-methylbutanal, hexanal, furfural, pent-3-en-2-one, acetic acid, propionic acid, 3- methylbutanoic acid, hexadecanoic acid, and so on.

Characteristic Volatile Components of Trifoliate Orange Peel (Poncirus trifoliata).

The volatile components of the peel of trifoliate orange {Poncirus trifoliata (L.) Raf.}, family Rutaceae, were investigated using SAFE technique after solvent extraction.
