, p. 75 - 88 (2007/10/02)
Fourteen aromatic ester oligomers have been synthesised, the majority of which have not been described previously.They can be considered as model compounds for liquid crystalline polyesters, and as such give useful information regarding the relationship between chemical structure and thermal properties.Such oligomers are also potentially important as precursors to liquid crystalline monomers.

Pinaceae; Brassicaceae; Solanaceae; Lamiaceae; hydroxybenzoic acid glucosides; hydroxybenzoylglucoses; glucose derivatives.Six hydroxybenzoic acid glucosides and three hydroxybenzoylglucoses were synthesized as reference substances and their content in plant extracts was determined by means of capillary GC and HPLC.The results suggest a wide distribution for the glucosides, whereas the glucose esters occur less frequently.
