Identification and in vitro Activity of Bioactive Compounds Extracted from Tussilago farfara (L.) Plant Grown in Lithuania and France

Abstract:

Background: The structures of bioactive compounds present in Tussilago farfara (T. farfara) leaves (L) and roots (R), to our knowledge, are not elucidated in the literature. This study investigated the composition of bioactive compounds and their antioxidant activity (AA) extracted from L and R of T. farfara aromatic plant collected in Lithuania (LT) and France (FR). Methods: Three in vitro antioxidant methods (DPPH, ABTS and FRAP method) were used to evaluate radical scavenging activity (RSA) of total phenolic compounds (TPC), flavonoids and flavonols compounds. Modern chromatographic and spectrometric analysis techniques were used; Online LC-MS technique was used to identify bioactive compounds in L and R extracts, while On-line HPLC-UV-DPPH was used to evaluate the RSC of each bioactive. Results: Extracts contain high amount of TPC with very good RSC. Eight bioactive compounds were identified in T. farfara L and R extracts, two of them (quercetin-pentoside and kaempferol-glucoside) previously not reported in this plant. Also, results showed that dicaffeoylquinic acids and quercetin pentoside were the major radical scavengers in L and R extracts. Conclusion: The present study provides new information about the chemical composition, bioactive structures and RSC of T. farfara L and R extracts from two geographical origins (Lithuania and France). This study demonstrate that T. farfara leaves and roots is a resource of bioactives which can reduces the risk of diseases and its effects which correlated with the antioxidant compounds.

About Journal

Founded:  In 2004, as the PHCOG.NET – a non-profit private organization dedicated to Natural Products Research leading to develop promising drugs. Our main mission is to make information on herbal drug research readily available in different formats to suit the individual needs. About Journal : Free Radicals and Antioxidants [ISSN: 2231-2536] is an online peer reviewed publication dedicated to publishing novel, original findings in the field of free radical biology and both natural and synthetic antioxidants. Free radicals, which are defined as molecules containing one or more unpaired electrons in their outmost atomic or molecular orbital have emerged as double edged swords.The Free Radicals and Antioxidants Journal aims to foster the dissemination of scientific information by publishing manuscripts that provide new insights into the biology of free radicals, including their generation, degradation, modulation, role in cellular function and cell signaling. The submission of uninvited expert reviews and research articles in all areas of Free Radical Biology and Antioxidants are also welcomed. Free Radicals and Antioxidants publishes full research papers presenting original, high quality research, critical review articles providing comprehensive analysis of research development within a defined area and editorial commentaries on key topical issues in Free Radical and Antioxidant Biology.
