Monolayers of some naturally occurring polycyclic compounds

Journal of Colloid and Interface Science, 1967
A detailed study of the monolayer characteristics of some films of amphipathic sterol or sterol-like, rigid polycyclic molecules, has been carried out. These include cholesterol, cholesteryl butyrate and caproate, lanosterol, α-amyrin, β-estradiol diacetate, and abietic acid.

Solid-phase extraction of polycyclic aromatic compounds

Journal of Chromatography A, 2000
Solid-phase extraction (SPE) for two groups of polyaromatic compounds--polycyclic aromatic hydrocarbons and naphthalenesulfonates--with completely different problems in the extraction process are reviewed. The sorbents used in each case and the different steps of SPE are studied.

Polycyclic aromatic compounds: Extraction and determination in food

Food Additives and Contaminants, 1994
Polycyclic aromatic hydrocarbons (PAHs) and polycyclic aromatic compounds (PACs) in general, comprise the largest class of known environmental carcinogens. Reports of some studies of total diet in a number of developed countries indicate that food constitutes an important source of exposure of man to PACs, although other authors have shown the need to ...

Syntheses of derivatives of polycyclic compounds

1949
In an attempt to convert β-(9-phenanthryl)-propionic acid to its 9:10-dihydride by high pressure hydrogenation, only β-(9-s-octahydrophenanthryl)propionic acid was obtained. β-(9-Phenanthryl)propionic acid was prepared, by standard reactions, from 9-chloromethyl phenantbrene, which was itself obtained by chloromethylation of phenanthrene.
