OBJECTIVE
This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects.
METHODS
DPPH assay and agar well diffusion method were carried out to determine antioxidant
BACKGROUND
Methanol extracts obtained from eight species belonging to four families of the Lamiales order native to Mexico were investigated for biological action.
OBJECTIVE
Cytotoxicity and antioxidant activity of methanol extracts have been investigated.
METHODS
Cytotoxic activity was evaluated by
The scavenging activities of six phenylpropanoid glycosides, i.e. leucosceptoside A and martynoside, isolated from Pedicularis alashanica Maxim, verbascoside, and pediculariosides A, M and N isolated from Pedicularis striata Pall ssp. arachnoidea Franch Tsoong, on superoxide anion and hydroxyl
OBJECTIVE
To study the antioxidative and iron chelating activities of phenylpropanoid glycosides (PPG) isolated from a Chinese herb Pedicularis striata.
METHODS
Antioxidative effects of PPG on lipid peroxidation induced by FeSO4-edetic acid in linoleic acid were measured by thiobarbituric acid
The antioxidative activities of six phenylpropaniod glycosides (PPG) extracted from Pedicularis striata and Pedicularis lasiophrys for inhibiting the lipid peroxidation induced by Fe2+/ascorbic acid in mouse liver microsome may be related to the number and steric position of phenolic hydroxyl groups
BACKGROUND
Pedicularis sibthorpii and P. wilhelmsiana are endemic species mainly found in North-West of Iran. Plants of genus Pedicularis produce some important poly-phenols and flavonoids. In the present work, total phenol and flavonoid contents of the mentioned species as well as their antioxidant
Five phenylpropanoid glycosides from Pedicularis, isoacteoside (1), acteoside (2), echinacoside (3), pedicularioside A (4), cistanoside D (5), and a chemically synthesised compound, permethylacteoside (6), as phenolic compounds can protect against oxidative hemolysis. The inhibitory activity is
Using pulse radiolysis technique, the reaction between hydroxyl radical and 7 phenylpropanoid glycosides: echinacoside, verbascoside, leucosceptoside A, martynoside, pediculariosides A, M and N which were isolated from Pedicularis were examined. The rate constants of these reactions were determined
The activities of six phenylpropanoid glycosides as chain-breaking antioxidants have been studied for the autoxidation of linoleic acid in cetyl trimethylammonium bromide (CTAB) micelles at 37 degrees C. Verbascoside, isoverbascoside, echinacoside and pedicularioside A, which possess four phenolic
