Mono- and sesquiterpenoids, flavonoids, lignans, and other miscellaneous compounds of Abies georgei.
A systematic phytochemical investigation of the aerial parts of Abies georgei yielded nine new and 72 known compounds, including four monoterpenes, four sesquiterpenes, 25 flavonones, 14 lignans, and 34 other chemical constituents. The new compounds included two monoterpenes (1 and 2), two sesquiterpenes (3 and 4), three flavonones (5, 6, and 7), and two other components (8 and 9). Their chemic...
The Raukaua genus of the family Araliaceae consists of 3 species, R. anomalus, R. edgerleyi and R. simplex, all endemic to New Zealand. The essential oil of R. edgerleyi and R. simplex consisted largely of monoterpenes. Limonene was the most abundant (23%) in R. edgerleyi and myrcene the most abundant (34%) in R. simplex. The oil of R. simplex lacked any significant sesquiterpenoids whereas bic...
Elevated levels of monoterpenes and diterpene resin acids are produced in the stems of lodgepole pine (Pinus contorta var latifolia) saplings when wounded and inoculated with the blue-stain fungus Ceratocystis clavigera or when wounded and treated with a pectic fragment from tomato leaves (PIIF) or a fungal cell wall fragment (chitosan). This induced defensive response (hyperoleoresinosis) is t...
species. Similar findings have previously been reported for M. piperita (Bricout & Paupardin, 1975) and M. rotundifolia (Bricout et al., 1978). Many of the calluses accumulate only the early precursors of the monoterpenes (namely geraniol, linalol and lavandulol), but some species give rise to cultures that accumulate monoterpenes characteristic of the intact plant. For example, cell lines from...
Monoterpenes are liquid hydrocarbons with applications ranging from flavor and fragrance to replacement jet fuel. Their toxicity, however, presents a major challenge for microbial synthesis. Here we evolved limonene-tolerant Saccharomyces cerevisiae strains and sequenced six strains across the 200-generation evolutionary time course. Mutations were found in the tricalbin proteins Tcb2p and Tcb3...
