Sesquiterpene lactones and their precursors as chemosystematic markers in the tribe Cichorieae of the Asteraceae

Contributions towards a revised infrageneric classification ofCrepis (Cichorieae, Compositae)

“…Chemo systematical evidence shows that C. multi caulis and C. pulchra (as representatives of the Lagoseris group) are very similar in the composition of their phytochemical compounds to the other 21 sampled Crepis species (all belonging to Crepis s.str. ), whereas Lapsana differs (Zidorn 2008). For all features shared by the species of sections Intybellia, Phaecasium, Lagoseris, Mi crocephalum and Pterotheca equivalent features could be found within Crepis s.str.…”

Antibacterial Activity of Naturally Occurring Compounds from Selected Plants

“…The experiment involved water, ethanol, ethyl acetate and acetone extracts from 10 plant species belonging to 4 the most important plant families. The following plants were used: (Saric, 1989) antibacterial, antifungal activity (Petrovic et al, 2004;Rani & Khullar, 2004;Mares et al, 2005) sesquiterpene lactones (Zidorn, 2008), inulin , flavonoids, coumarins (Dem'yanenko & Dranik, 1971), tannins, phenolic acids ( Sareedenchai & Zidorn, 2010 ) Fam. Lamiaceae Salvia officinalis for disorders of the digestive system, as antiseptic for sore throats, ulcers, to treat insect bites, mouth and gum infections and vaginal discharge for night sweats (Saric, 1989) antibacterial, antifungal, antiviral activity ( Velickovic et al, 2003;Nolkemper et al, 2006;Horiuchi et al, 2007;Weckesser et al, 2007) simple phenols, phenolic acids, flavonoids, coumarins, tannins, terpenoids (Lu & Foo, 1999;2002;Durling et al, 2007) Melissa officinalis to reduce indigestion and flatulence, as a mild sedative, to treat headache, migraine, nervous tension and insomnia, to treat cold, fever and cough (Saric, 1989) antibacterial, antifungal, antiviral activity ( Iauk et al, 2003;Ertürk, 2006;Nolkemper et al, 2006) flavonoids ( Herodež et al, 2003;Patora & Klimek , 2002), phenolic acids (Herodež et al, 2003;Canadanović -Brunet et al, 2008), simple phenols, tannins (Hohmann et al, 1999) Clinopodium vulgare as a heart tonic, an expectorant, as a diuretic (Saric, 1989) as an antiseptic for wounds and injuries (Opalchenova and Obreshkova, 1999).…”

Development of Anticancer Agents from Plant-Derived Sesquiterpene Lactones

“…There are more than 5000 SQLs characterized as secondary metabolites in species of the plant kingdom, in particular in the family Asteraceae [1]. This type of NP has received considerable attention because of their diverse structure skeletons and chemotaxonomic significance [2, 3], as well as their potent bioactivities, including antibiotic, antitumor, antiulcer, insect-feeding deterrent, phytotoxic, and schistosomicidal effects [4, 5]. …”
