abietic acid/abies

Abietic acid is a major component of the rosin fraction of oleoresin synthesized by grand fir (Abies grandis), lodgepole pine (Pinus contorta), and many other conifer species as a defensive secretion against insect and pathogen attack. The diterpenoid resin acid is derived from geranylgeranyl

In our previous study, Abies balsamea (L.) Mill., a plant used in Cree traditional medicine, had a strong effect on the regulation of glucose homeostasis in liver cells. This study aimed to isolate and identify its active constituents using a bioassay-guided fractionation approach as well as to

The oleoresin secreted by grand fir (Abies grandis) is composed of resin acids derived largely from the abietane family of diterpene olefins as precursors which undergo subsequent oxidation of the C18-methyl group to a carboxyl function, for example, in the conversion of abieta-7,13-diene to abietic

Oleoresin (pitch) is a defensive secretion composed of monoterpene olefins (turpentine) and diterpene resin acids (rosin) that is produced in grand fir (Abies grandis Lindl.) stems in response to wounding. Monoterpene and diterpene biosynthesis are coordinately induced in wounded stems as determined

A study to assess exposure to potential respiratory hazards in a large lumber mill processing spruce (Picea engelmannii and glauca), pine (Pinus contorta), and fir (Abies lasiocarpa) used a random sampling strategy to assess exposures for all jobs in the sawmill, planer mills, and yard. Personal

(-)-Abietic acid, the principal diterpenoid resin acid of the wound-induced oleoresin secreted by grand fir (Abies grandis), is synthesized by the cyclization of geranylgeranyl diphosphate to (-)-abieta-7(8),13(14)-diene, followed by sequential three-step oxidation of the C-18 methyl group of the
