Baccharis trinervis gave essential oils which were predominantly terpenoid
in nature with a few aliphatic and aromatic compounds as minor and trace constituents.
contents of traditionally used ethnobotanically important plants (n=25) were determined.
This is not always the case, however, as 1,8-cineole, a terpenoid
, was demonstrated to cause depolarization of the resting membrane and to block excitability, mainly indirectly, via the effect of depolarization voltage-dependent [Na.
Its toxicity is attributed to the presence of a hepatotoxic terpenoid
known as atractyloside, a powerful inhibitor of cellular respiration and ATP synthesis.
Groups of related flavoring agents are considered together, among them alicyclic ketones, secondary alcohols, and related esters; aliphatic acyclic and alicyclic terpenoid
tertiary alcohols and structurally related substances; benzul derivatives; and phenol and phenol derivatives.
aegypti larvae suggesting the presence of larvicidal metabolites such as terpenoid
in Dictyota and Padina.
Only trace of the convulsant thujone, (a terpenoid
ketone), could be detected at any time in vegetative cycle of Spanish sage.
As shown in Table 2, hexane extract which contains only terpenoid
compounds has antibacterial activity against all tested bacteria but smallest compared to other extracts.
1996) Glyceraldehyde 3-phosphate and pyruvate as precursors of isoprenic units in an alternative non-mevalonate pathway for terpenoid
1990) found a negative correlation between consumption and concentration of the terpenoid
pinifolic acid in Scots pine (Pinus sylvestris); a similar observation was made by Sunnerheim-Sjoberg (1992) with a different monoterpene [(-)-angelicoidenol-2-0-[beta]-D-glucopyranoside] in Scots pine.
1]) is the size-resolved mass distribution yield of SOA formed by gas-phase reactions between ozone and the terpenoid
, which is the ratio of the change in mass of SOA formed to the change in mass of terpenoid
consumed; [GAMMA](-) is a conversion factor to change units of ppb/h to [mu]g/[m.
