abstract = "Fatty acids (FAs), sterols, and triterpenes of dichloromethane extracts of the fruits of 8 Heracleum L. taxa (Apiaceae) from
southeastern Europe were investigated by gas chromatography with flame ionization detector and gas chromatography with
mass spectrometry. In order to analyze the FAs, their volatile methyl esters were obtained by saponification and subsequent
esterification of oily supernatants of the fruit extracts. Dominant was petroselinic acid (42.8%-56.5%), followed by linoleic
(20.3%-33.3%) and oleic acids (12.3%-13.7%). Sterols and triterpenes were analyzed as volatile derivatives obtained by the
silanization of residual unsaponifiable fractions. Among them, the most abundant was β-sitosterol (44.9%-56.9%), followed by
stigmasterol (15.7%-25.0%), Δ7-stigmastenol (6.6%-12.5%), and campesterol (5.2%-8.1%). The quantity of petroselinic acid
was also determined by the external standard method (298.8-433.4 mg/g of oily supernatant). The obtained results show that
the investigated plants are potential valuable sources of the compounds utilized in different industries.",
