Volatile Components of the Kuromoji Essential Oil (Lindera umbellata Thunb.) and the Utilization for Touch Care Treatment.

The volatile components of kuromoji oil (Lindera umbellata Thunb.) obtained in Shizuoka Pref. were analyzed by GC/MS.

Characteristic Odor of the Japanese Liverwort (Leptolejeunea elliptica).

The volatile components produced by Leptolejeunea elliptica (Lejeuneaceae), which is a liverwort grown on the leaves of tea (Camellia sinensis), were collected and analyzed using headspace solid-phase microextraction-gas chromatography/mass spectrometry (HS-SPME-GC/MS). 1-Ethyl-4-methoxybenzene (1), 1-ethyl-4-hydroxybenzene (2), and 1-acetoxy-4-ethylbenzene (3) were identified as the major components together with several other phenolic compounds, including 1,2-dimethoxy-4-ethylbenzene, and 4-ethylguaiacol in addition to sesquiterpene hydrocarbons, such as α-selinene, β-selinene, β-elemene, and β-caryophyllene. GC/Olfactometry showed the presence of linalool, acetic acid, isovaleric acid, trans-methyl cinnamate, and trans-4,5-epoxy-(2E)-decenal, as the volatile components produced by L.

The characteristic smell emitted from two scale insects, and .

Unlabelled: The volatile components emitted from two scale insects, and , were identified using GC-MS analysis. The major volatile components of the solvent extract from were α-humulene (35.8%) and δ-cadinene (17.

A Fragrant Environment Containing α-Pinene Suppresses Tumor Growth in Mice by Modulating the Hypothalamus/Sympathetic Nerve/Leptin Axis and Immune System.

The environment is thought to affect outcomes in patients with cancer; however, this relationship has not been proven directly. Recently, an enriched environment, as a model of a positive environment, has been shown to suppress tumor growth by lowering leptin production through a pathway involving the hypothalamus/sympathetic nerve/leptin axis. We previously reported that a fragrant environment (FE) containing α-pinene suppressed tumor growth in mice; however, the underlying mechanism has not been elucidated.

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.

Volatile Components Emitted from the Liverwort Marchantia paleacea subsp. diptera.

The volatile components from the thalloid liverwort, Marchantia paleacea subsp. diptera were investigated by HS-SPME-GC-MS analysis. The monocyclic monoterpene aldehyde, perillaldehyde was identified for the first time as the major component and its content was about 50% of the volatiles, along with β-pinene, limonene, β-caryophyllene, α-selinene and β-selinene as minor volatiles.

Characteristic volatile components of Kabosu (Citrus sphaerocarpa Hort. ex Tanaka).

The volatile components of both peel and juice of Japanese citrus, Kabosu (Citrus sphaerocarpa Hort. ex Tanaka) were investigated using SAFE (Solvent Assisted Flavor Evaporation) technique after solvent extraction. In this study, wine lactone, rose oxide, (2E)-4,5-epoxy-2-decenal, mintsulfide, and indole were newly identified from Kabosu.
