A previously undescribed triterpenoid saponin, 3-O-[α-l-rhamnopyranosyl-(1→2)-{β-d-glucopyranosyl-(1→6)-}β-d-galactopyranosyl-(1→2)-β-d-glucuronopyranosyl]-sophoradiol (1), in addition to twenty-nine known constituents (2-30) were isolated from the aerial parts of Genista numidica Spach. Structures

The aim of this study was focused on the polyphenolic composition and antioxidant capacity of Genista tinctoria L. and Genistella sagittalis (L.) Gams. A qualitative and quantitative characterization of the main phenolic compounds from the extracts were carried out using a HPLC-MS method. The total

Phenolic extracts of aerial parts of Genista ferox have been characterized and evaluated for their pharmacological properties which are still not reported. The total phenol and flavonoid contents in the extracts were estimated spectrophotometrically via the Folin-Ciocalteu and aluminium chloride

Genista species are sources of antioxidant phenolic compounds such as O- and C-glycosylflavonoids and isoflavonoids. A combination of a DPPH scavenging assay with HPTLC-MS, a fast and efficient method for identification of bioactive compounds, has been applied for evaluation of the radical scavenging

OBJECTIVE To evaluate the influence of an extract of Genista tinctoria L. herba (GT) or methylparaben (MP) on histopathological changes and 2 biomarkers of oxidative stress in rats subchronicly exposed to bisphenol A (BPA). METHODS Adult female Wistar rats were orally exposed for 90 d to BPA (50

The flavonoid fraction of the aerial parts of Genista cadasonensis Valsecchi (Leguminosae), an endemic plant from Sardinia, was examined and compared with the flavonoid pattern already known in the Genista genus. This comparison evidenced the endemic nature of this species, showing the presence of a

Many Genista species (Leguminosae), containing isoflavones as biologically active substances, show interesting biological properties such as hypoglycemic, antiinflammatory, antiulcer, spasmolytic, antioxidant, estrogenic and cytotoxic activity against different human cancer cell lines. In this work,

The inhibition of α-glucosidase and glucose-6-phosphatase, two enzymes involved in the carbohydrate metabolism, is an important target to control glycaemia on individuals with type 2 diabetes. In this work we report for the first time the inhibition of both enzymes by the antihyperglycemic n-butanol

OBJECTIVE Genista tenera is a plant endemic to the island of Madeira and is used in folk medicine to control diabetes. In the present work we evaluate the antihyperglycaemic activity of its n-butanol extract and determine its chromatographic profile. In addition, this extract, the ethyl acetate and

In order to characterize and study the bioactivities of individual plant species and to determine how these characteristics are modified when preparing blends, five different plant species were selected: Erica australis L., Genista tridentata L., Melissa officinalis L., Mentha spicata L., and

Oxidative stress is a major cause of drug-induced hepatic diseases and several studies have demonstrated that diet supplementation with plants rich in antioxidant compounds provides a variety of health benefits in these circumstances. Genista quadriflora Munby (Gq) and Teucrium polium geyrii Maire

Ethnopharmacological surveys on Portuguese flora reveal that Genistatridentata L. is a shrub used in traditional medicine for the treatment of various inflammation-related health problems, although scientific support of its benefits is still necessary. In order to establish the
