Sažetak
The aim of the present study was to analyse the methanol extracts from the aerial and the underground parts of Telekia speciosa (Schreb.) Baumg by HPLC and determine their antioxidant capacity. In addition, volatiles from both parts of the plant were analysed. The chlorogenic acid (CGA) and caffeic acid derivatives were present in the extracts. The CGA content was 977.8±85 mg per 100 g extract for underground and 272.0±18 mg per100 g extract for aerial parts of T. speciosa. The antioxidant capacity, determined by DPPH and FRAP method, was on average three and a half times higher for the extract of the underground parts in comparison with the extract of the aerial plant parts. The volatile constituents determined by GC-FID/MS were characterized by the presence of a high concentration of oxygenated sesquiterpenes. The obtained results contribute to better knowledge of phytochemical properties of T. speciosa, which is traditionally used in bronchial asthma therapy.
