Volatiles of <i>Helichrysum italicum</i> (Roth) G. Don from Croatia

<div><p><i>Helichrysum italicum</i> (Roth) G. Don is a flowering plant of the family Asteraceae. It is rich in oil that is used for different medicinal purposes and in fragrance industry. Volatile profile of four populations of <i>H. italicum,</i> collected from natural habitat in Dalmatia (Croatia), was analysed by capillary GC–MS. Sample from BraČ Island had α-<i>trans</i>-bergamotene (10.2%) and β-acoradiene (10.1%) as the majors, whereas sample collected on Biokovo Mt. was rich in neryl acetate (8.1%). β-Acoradiene was also the main constituent of sample collected near Tijarica, whereas rosifoliol (8.5%) was the most abundant constituent in sample collected near Makarska. Presented results show the influence of environmental conditions on chemical differentiation of the volatiles of <i>H. italicum</i> from Croatia.</p></div

Evaluation of chemical profile and antioxidant activity of <i>Tripleurospermum insularum</i>, a new species from Turkey

<div><p>This article presents the very first phytochemical investigation on new species <i>Tripleurospermum insularum</i> Inceer & Hayırlıoglu-Ayaz. The volatile profile of odorous parts of the plant was analysed by GC/MS, and compounds were identified in headspace and essential oil obtained from aerial parts, representing 70.81% and 92.44% in total, respectively. The major volatiles were <i>n</i>-alkanes (38.43–59.22%), while essential oil was also rich in globulol (13.45%) and β-sesquiphellandrene (9.29%). The content of phenolic compounds in methanolic extract and oil was 3621.62 and 14.4 mg GAE/100 g of dry plant, respectively. Moreover, potential medicinal effects were found in mean of antioxidant activity of this plant measured by using two different assays: radical-scavenging activity and ferric-reducing activity. Samples revealed values ranging from 0.33 to 146.80 μmol TE/100 g for DPPH assay, and from 2.29 to 5414.17 μmol AAE/100 g for FRAP assay.</p></div
