The leaf terpenoid compositions of nine Lauraceae species, viz., Neolitsea pallens, Lindera pulcherrima, Dodecadenia grandiflora, Persea duthiei, Persea odoratissima, Persea gamblei, Phoebe lanceolata, Cinnamomum tamala, and Cinnamomum camphora, collected from the Himalayan region (India) were examined by GC, GC/MS, and NMR analyses in order to determine the similarities and differences among their volatile constituents. Furano-sesquiterpenoids were the principal constituents of N. pallens, L. pulcherrima, and D. grandiflora. (E)-Nerolidol, limonene, beta-pinene, and alpha-pinene were the major constituents of P. duthiei; alpha-pinene, sabinene, and beta-caryophyllene were predominant in P. odoratissima, while the oils of P. gamblei and P. lanceolata possessed beta-caryophyllene as common major constituent. C. camphora and C. tamala were marked by the presence of camphor and cinnamaldehyde, respectively. Cluster analysis of the oil composition was carried out in order to discern the differences and similarities within nine species of six genera of Lauraceae.

“…The chemical composition of C. holtziana and C. myrrha gum resins has been reported elsewhere (Provan et al, 1987;Cavanagh et al, 1993;Zhu et al, 2001Zhu et al, , 2003Dekebo et al, 2002;MortezaSemnani and Saeedi, 2003;Marongiu et al, 2005;Hanus et al, 2005;Ahmed et al, 2006). These studies show that the resins comprise mainly sesquiterpene hydrocarbons and furanosesquiterpenes, some of which are known from unrelated studies to be effective arthropod repellents, e.g.…”

Antiectoparasitic activity of the gum resin, gum haggar, from the East African plant, Commiphora holtziana

et al. 2008

a b s t r a c tThe mechanism of ixodid tick (Acari: Ixodidae) repellency by gum haggar, a resin produced by Commiphora holtziana (Burseraceae), was investigated by evaluating activity against the cattle tick, Boophilus microplus. In an arena bioassay, a hexane extract of the resin of C. holtziana exhibited a repellent effect lasting up to 5 h. The hydrocarbon fraction of the resin extract was shown to account for the repellent activity, and was analysed by coupled gas chromatography-mass spectrometry (GC-MS). Major sesquiterpene hydrocarbons were tentatively identified as germacrene-D, d-elemene and b-bourbonene. The identity and stereochemistry of the former compound was confirmed as the (+)-isomer by peak enhancement using enantioselective GC, whereas the latter 2 compounds, which are most likely degradation products of germacrene-type precursors, were identified through isolation by preparative gas chromatography followed by microprobe-NMR spectroscopy. GC comparison of gum haggar with another resin, C. myrrha, which was inactive in the tick bioassay, showed that the latter contained much lower levels of these hydrocarbons. To assess the suitability of the gum haggar resin as a general acarine repellent, further tests were made on a major acarine pest of European and US animal husbandry systems, the red poultry mite, Dermanyssus gallinae (Acari: Dermanyssidae). Gum haggar extract, and the isolated hydrocarbon fraction, showed strong repellent effects in an olfactometer assay, and again gum myrrh showed no effect. These findings provide a scientific basis for the observed anti-tick properties of gum haggar, and demonstrate the potential for its development as a general acarine repellent for use in animal husbandry systems.

“…Research on the characterisation of essential oils of several Boswellia species has been conducted, but B. papyrifera has received the most attention. Major components in the essential oils of B. papyrifera of Ethiopian origin are octyl acetate (50-90%), α-pinene (6.1%), camphene (0.6%), β-pinene (2.0%), myrcene (1.7%), limonene (4.8%), 1-octanol (5.9%), linalool (3.6%), octyl acetate (46.8%) and geraniol (1.1%) (Dagne et al 1997, Dekebo et al 2002. The essential oils of B. neglecta gums are mainly composed of hydrocarbon monoterpenes of α-thujene (26%), α-pinene (20%), 4-terpineol (15.7%), p-cymene (4.5%), camphor (2.8%) and β-pinene (1.9%) (Dagne et al 1997).…”
