The present invention relates to a method for separating metal ions from a liquid, which method comprises contacting liquid comprising metal ions with non-functionalized cellulose, adsorbing the metal ions to the cellulose, and separating the liquid from the cellulose, wherein the liquid is an essential oil.

Removal of metal ions from essential oils

A method for extracting a polycyclic aromatic hydrocarbon from a material such as tobacco or tobacco extracts or other materials comprises treating the material with a molecularly imprinted polymer selective for the hydrocarbon in the presence of a low polarity medium.

Method for removing polycyclic aromatic hydrocarbons

The invention is related to compounds of general formula (I) wherein R is methyl, ethyl, n-propyl, iso-propyl, n-butyl or allyl; R' is methyl, methoxy, fluoro, chloro, bromo, trifluoromethyl, or OCH.sub.x F.sub.y, wherein

Quinoline derivatives

The invention is related to compounds of general formula (I) ##STR1## wherein R is Me, Et, n-Pr, iso-Pr, n-Bu, iso-Bu, sec.-Bu or allyl; R' is hydrogen, Me, MeO, fluoro, chloro, brorno, CF.sub.3, or OCH.sub.x F.sub.y ; R' is hydrogen or fluoro, with the proviso that R' is fluoro when R' is fluoro; and further when R' and R' are both hydrogen, R is not Me; R.sub.4 is selected from hydrogen and pharmaceutically acceptable inorganic and organic cations; R.sub.5 is selected from MeS, EtS, n-PrS, iso-PrS, MeSO, EtSO, MeSO.sub.2 and EtSO.sub.2 ; wherein x=0-2, y=1-3 with the proviso that x+y=3; and Me is methyl, Et is ethyl, Pr is propsy and Bu is butyl; and any tautomer, optical isomer and racemate thereof. The invention also relates to pharmaceutical compositions containing a compound of the general formula (I) together with a pharmaceutically acceptable carrier. Included are also processes for the preparation of the compounds of formula (I), as well as methods for the treatment of mammals suffering from diseases resulting from autoimmunity and pathological inflammation by administering of a compound having the formula (I) to said mammal.
