Verbena carolina L. (Verbenaceae) is used as a decoction in Mexican folk medicine with applications against digestive problems and for dermatological infections. The present work firstly reported HPLC analysis, as well as the free radical scavenging capacity of the extracts and isolated
OBJECTIVE
To isolate and identify the chemical constituents from Verbena officinalis.
METHODS
The compounds were isolated by means of chromatography and the structures were determined on the basis of physical and spectral analysis.
RESULTS
Four compounds were isolated and identified as apigenin (I),
Two new iridoids, 3-(5-(methoxycarbonyl)-2-oxo-2H-pyran-3-yl)butanoic acid, named verbeofflin I (1), and 7-hydroxydehydrohastatoside (2), were isolated from the aerial part of Verbena officinalis L, along with three known iridoids, verbenalin (3), 3,4-dihydroverbenalin (4), hastatoside (5) by means
Verbena and lemon verbena aqueous preparations were investigated for their content of constituents, especially polyphenols by HPLC/DAD/ESI/MS analysis because they are used worldwide as herbal teas. The main class of compounds of these plants were phenylpropanoids (from 16 to 120 mg/g of dried
This report presents the first ultra-high performance supercritical fluid chromatography diode array detector based assay for simultaneous determination of iridoid glucosides, flavonoid glucuronides, and phenylpropanoid glycosides in Verbena officinalis (Verbenaceae) extracts. Separation of the key
In an attempt to locate the biologically active fraction(s) of the plant Verbena officinalis Linn. (Verbenaceae), a preliminary screening of successive petroleum ether, chloroform and methanol extracts of aerial parts for antiinflammatory activity using carrageenan paw oedema model was carried out.
