Carboxylic acids of phenolic complexes from Veronica teucrium L.

Phytochemical Characterization of Veronica officinalis L., V. teucrium L. and V. orchidea Crantz from Romania and Their Antioxidant and Antimicrobial Properties

Aerial parts of Veronica species are used in Romanian traditional medicine for the treatment of various conditions like kidney diseases, cough, and catarrh, and are known for their wound-healing properties. In the present study, the phenolic and sterolic content and the antioxidant and antimicrobial activities of three Veronica species (Plantaginaceae), V. officinalis L., V. teucrium L. and V. ...

Separation of Carboxylic Acids from Aqueous Solutions using Hollow Fiber Membrane Contactors

Separation of formic, acetic, and propionic acids from the aqueous stream using membrane solvent extraction has been studied using three different membrane contactors made of polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) using two different solvents; including ethyl acetate (EA) and diisopropyl ether (DIPE). The efciency of the membrane and e...

Phytotoxicity of Phenolic Acids From Cereals

External flavonoid aglycones from Veronica chamaedrys L. (Scrophulariaceae).

External flavone aglycones in the overground parts of Veronica chamaedrys L. (Scrophulariaceae) have been analysed by isocratic reversed-phase high performance liquid chromatography. Luteolin, apigenin, luteolin-3'-methyl ether and scuterallein-6,4'-dimethyl ether have been identified. The latter compound is a new flavonoid identified in Veronica genus.

Phenolic Acids and Flavonoids in Hypericum Perforatum L. Hairy Roots

Investigations have been made to develop an efficient protocol for identification and quantification of phenolic acids and flavonoids in hairy roots (HR) of Hypericum perforatum L. HR were induced from root segments of in vitro grown seedlings from H. perforatum, after co-cultivation with Agrobacterium rhizogenes A4. Transgenic status of HR was confirmed by PCR analysis using rolB specific prim...
