background and objectives: residues of medicinal plants after extraction and weeds are suitable candidates for bioethanol production. significant barriers exist to make the conversion of lignocellulosic feedstock to biofuel cost effective and environmentally friendly; one of which is the lignin polymer. brassicaceae family is one of the potential targets for biofuel production. the structural c...

Anthocyanins, Flavonoids, Chalcone Synthase, Genetic Control, Matthiola incana Chalcone synthase activity was demonstrated in enzyme preparations from flowers of defined genotypes of Matthiola incana (stock). The product formed from 4-coumaroyl-CoA and malonylCoA was naringenin and not the isomeric chalcone, because chalcone isomerase was also present in the reaction mixture. Chalcone synthase ...

The viscid exudate found on fronds o f the fern, Cheilanthes kaulfussii, consists of terpenoids in which flavonoid aglycones are dissolved. One of the terpenes is shown to be em-kaur-16-en-19-oic acid. The farinose frond exudate of Notholaena pallens contains this acid as the major constituent and its 3 /?-hydroxy derivative, together with flavonoid aglycones as minor components. In N. incana, ...
