In the present study, the in vivo anti-inflammatory activity of Agrimonia pilosa Ledeb (AP) ethanol extract was confirmed in experimental animal models, including xylene-induced ear edema in mice and carrageenan-induced paw edema in rats. Tiliroside, the major component of AP extract, was isolated
The methanolic extract from the flowers of Tilia argentea (linden) was found to show a hepatoprotective effect against D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced liver injury in mice. By bioassay-guided separation using in vitro D-GalN-induced damage to hepatocytes, five flavonol
BACKGROUND
Multidrug resistance (MDR) in cancer represent a major hurdle in chemotherapy. Previously, the methanol extract of the medicinal spice Xylopia aethiopica displayed considerable cytotoxicity against multidrug resistant (MDR) cancer cell lines.
METHODS
The present study was designed to
BACKGROUND
Flavonoids have physiological activity and a variety of pharmacological properties, including anticancer activity in vitro, but structure-anticancer activity relationships are unclear.
OBJECTIVE
The objectives of this work were to investigate the activity of dietary flavonol congeners
Hypertension is a disease of high prevalence and morbidity where vascular inflammation and associated oxidative stress (endothelial dysfunction) is the underlying cause of this pathology. We are reporting the antihypertensive activity of extracts and fractions of Malva parviflora in mice with
Elaeagnus oldhamii Maxim. is a commonly used traditional herbal medicine. In Taiwan the leaves of E. oldhamii Maxim. are mainly used for treating lung disorders. Twenty five compounds were isolated from the leaves of E. oldhamii Maxim. in the present study. These included oleanolic acid (1),
Three flavonoids were isolated from the whole plants of Waltheria indica and biological properties investigated. On the basis of their spectroscopic data, these compounds were identified as (-)-epicatechin, quercetin, and tiliroside. These flavonoids significantly and dose-dependently inhibited the
We attempted to isolate a carcinogenic substance from bracken fern (Pteridium aquilinum), a naturally occurring toxicant responsible for the production of chronic enzootic hematuria and urinary bladder cancer of cattle and carcinogenic for various target organs of several species. Hot methanol
BACKGROUND
Pavonia xanthogloea is traditionally used as an antimicrobial and anti-tumour medicine in Southern Brazilian region. However, investigations about this species are still incipient.
UNASSIGNED
The study postulated that P. xanthologea specie present some phenolic compound and present some
Malva pseudolavatera Webb & Berthel. is a plant from the Malvaceae family that has long been included in the human diet due to its various curative effects. Many plant leaf extracts from the various species of Malva genus have been reported to possess anti-cancer properties,
Wissadula periplocifolia (L.) C. Presl (Malvaceae) is commonly used in Brazil to treat bee stings and as an antiseptic. The antioxidant properties of its extracts have been previously demonstrated, thus justifying a phytochemical investigation for its bioactive phenolic constituents. This has
A new natural C-benzylated chalcone, 2',4'-dihydroxy-3'-(2-hydroxybenzyl)-6'-methoxychalcone (2), along with two other flavonoids, tiliroside and kaempferol 3-O-rutinoside, and an oxoaporphine alkaloid, lanuginosine were isolated from the aerial parts of Ellipeiopsis cherrevensis (Annonaceae). Two
