Abstract:
n-Hexane and chloroform fractions of aerial parts and roots of Cicuta virosa L. were investigated by GC-MS. As a result of the study 25 fatty acids and their esters have been identified. Two unsaturated esters such as linoleic acid ethyl ester (IX, 16.66%), and n- hexadecanoic acid ethyl ester (VII, 10.12%), the fatty acid n-hexadecanioc acid (VI, 8.10%) made up the bulk of the aerial parts. Four unsaturated esters such as linoleic acid ethyl ester (IX, 10.15%), dibutylphthalate (XII, 9.55%), n-hexadecanoic acid ethyl ester (VII, 8.19%) and 9, 12, 15 - octadecatrienoic acid ethyl ester (X, 5.9

ABSTRACT Alkane biosynthesis in the bacterium Vibrio furnissii M1 involves the synthesis of long-chain alkanes via 1-alcohol. Evidence for this novel pathway are the following.

This result cannot be explained by the decarbonylation pathway.

The chemical composition of the essential oils from aerial parts of two taxa of Centaurea belonging to subgenus Acrolophus, Centaurea diffusa Lam. and C. micrantha Hoff. ssp. melanosticta (Lange) Dostàl, respectively collected in Croatia and Spain, were evaluated by GC and GC-MS. The main components of C. diffusa were hexadecanoic acid (31.1%), ( Z,Z)-9,12-octadecadienoic acid (10.7%) and damascenone isomers (6.4%), whereas hexahydrofarnesyl acetone (27.8%), hexadecanoic acid (8.3%) and caryophyllene oxide (6.4%) were the most abundant components of C. micrantha ssp. melanosticta.
