摘要:

AbstractThe definition of aromatherapy as well as the aromatherapeutical uses of fragrance compounds and essential oils are discussed. Various methods—mainly physiological—to investigate the efficacy of fragrances are sh

摘要:

AbstractThe compositions ofAbies sachalinensis(Fr. Schm.) Mast. andA. mayrianaMiy. et Kudo needle essential oils were analysed on non‐chiral and chiral GC columns. Both oils were characterized by high proportions of bornyl acetate and (‐)‐camphene. The (‐)‐enantiomers of α‐ and β‐pinene, camphene, limonene and β‐phellandrene predominated and amounted to 80% of the monoterpene hydrocarbons. The monoterpene composition was used to study the differences between the two species. Cluster analysis tended to separateA. sachalinensisandA. mayrianainto two major groups. In addition, both groups were divided into subgroups on the basis of the (‐)‐β‐phellandren

摘要:

AbstractThe composition of the essential oils from different aerial parts ofArtemisia argenteaL'Hér. was analysed by GC and GC‐MS. The oils were isolated separately from flower heads, and from leaves collected during the flowering period and the vegetative phase of the plant. The composition of the oils did not differ to a large extent. The three oil samples consisted mainly of monoterpenes (67–73%). α‐Phellandrene (25–27%) was the dominant component of the oils analysed, while isopinocamphone (cis‐3‐pinanone; 7–12%) was the second most important monoterpene. The sesquiterpene fraction amounting to 21–27% of the oils, was dominated by β‐caryophyllene (5–8%) and β‐eudesmo

摘要:

AbstractThe composition of the essential oil ofBlumea brevipes(Oliv.&Hiern) Willd. isolated by hydrodistillation was analysed by GC and GC‐MS. Sixty‐eight compounds constituting about 94% of the oil were identified. The main components were terpinen‐4‐ol (27.6%), germacrene‐D (15.4%), sabinene (8.0%) and α‐terpinene (5.5%). The essential oil composition ofB. brevipespresented here (terpinenol‐germacrene‐type) is different from that of otherBlumea

摘要:

AbstractThe stem‐leaf liverwort,Chiloscyphus pallidus(Mitt.) Engel&Schuster (Jungermanniales) emits an intense smell reminiscent of the stink bug (Pentatomidae). An ether extract of this species which was collected in New Zealand, was analysed by GC‐MS. The major constituent was identified as (E)‐dec‐2‐enal by spectral data of its 2,4‐dinitrophenylhydrazone and oxime‐tert‐butyldimethylsilyl derivatives. The stereochemistry was decided astransby1H‐NMR decoupling experiments of the 2,4‐dinitrophenylhydrazone. Although it is well known that the stink bug emits (E)‐dec‐2‐enal as its characteristic smell, this was its first identification in the volatile c

摘要:

AbstractSteam‐distilled volatile (essential) oil fromHeteromorpha trifoliata(Wendl.) Eckl.&Zeyh. (Apiaceae) was tested for antimicrobial activities. Twenty‐five bacterial and four fungal species were used in this study as test organisms. These included animal and plant pathogens, food poisoning and spoilage bacteria and mycotoxigenic fungal strains. The volatile oil exhibited considerable inhibitory activities against all the test organi
