From the capitula of Helichrysum compactum, the flavonoids apigenin, kaempferol, luteolin, naringenin, 3,5-dihydroxy-6,7,8-trimethoxyflavone, kaempferol-3-O-glucoside, luteolin-7-O-glucoside and luteolin-4',7-di-O-glucoside and from the leafy stems apigenin, kaempferol, luteolin, quercetin,

BACKGROUND In Madeira Archipelago there are four endemic Helichyrsum species and three of them are used in the traditional medicine. Helichrysum monizii is a rare endemism with very scarce information available concerning its uses in the local traditional medicine. OBJECTIVE The aim of this work was

The chemical composition and antioxidant properties of the essential oil and EtOH extract of immortelle (Helichrysum italicum (Roth) G.Don subsp. italicum, Asteraceae) collected in Montenegro were evaluated. The essential oil was characterized by GC/MS analysis, and the content of total phenolics

Methanol extract of Helichrysum foetidum Moench (Asteraceae) was investigated for antioxidative properties. The antioxidant activities were investigated by 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging, ß-carotene/linoleic

Helichrysum graveolens (Bieb.) Sweet (Asteraceae) grows widely in Turkey. Capitulums of H. graveolens are used in the treatment of many diseases such as jaundice and wound healing and as a diuretic in the rural areas of Anatolia. The decoction from the capitulums of the plant is consumed for the

Liquid Chromatography-Ion Trap Mass Spectrometry with an atmospheric pressure chemical ionization (APCI) interface in the negative and positive-ion modes in parallel to UV-diode-array detection (DAD), was applied for the rapid detection/characterization in crude extracts of the water-soluble

OBJECTIVE The aqueous methanolic extracts of two plants from Algeria, Helichrysum stoechas subsp. rupestre and Phagnalon saxatile subsp. saxatile, were investigated for their antioxidant activity. METHODS Total phenolics, flavonoids, and tannins were determined by spectrophotometric techniques. In

Arzanol is a naturally-occurring prenylated acylphloroglucinol isolated from Helichrysum italicum and exhibiting anti-oxidant, antibiotic and antiviral activities. The molecule contains an α-pyrone moiety attached to the phloroglucinol moiety through a methylene bridge. The presence of several

The choleretic, hepatoprotective and detoxifying activities of the inflorescence of Helichrysum arenarium (L.) Moench (everlasting, immortelle: Asteraceae-Helichrysi flos syn. Stoechados flos) have been known for a long time from herbal medicine in Hungary. Antioxidant properties of its main

Helichrysum plicatum DC. is widely used in folk medicine in treating a variety of health disorders. The aim of this study was to examine the influence of different extraction solvents on the chemical composition, antioxidant potential, and antimicrobial activities of H. plicatum.

We evaluated the in vitro antioxidant property and phytochemical constituents of the aqueous crude leaf extract of Helichrysum pedunculatum. The scavenging activity on superoxide anions, DPPH, H₂O₂, NO and ABTS; and the reducing power were determined, as well as the flavonoid, proanthocyanidin and

Organic extracts of the flowers of Helichrysum kraussii and H. odoratissimum contain several bioactive flavonoids, characterized by 'H NMR, '3C NMR and mass spectrometry. Four flavonoids, 5,6-dihydroxy-3,7,8-trimethoxyflavone, 5,7-dihydroxy-3-methoxyflavone, 3',4',5,7-tetrahydroxy-3-methoxyflavone

Helichrysum species (Asteraceae) are widely found in Anatolia. Decoction prepared from the capitulums of Helichrysum plicatum ssp. plicatum is used to alleviate the symptoms of diabetes mellitus in folk medicine. In the present study, the hypoglycaemic and antioxidant potential of Helichrysum

BACKGROUND Many oxidative stress related diseases are as a result of accumulation of free radicals in the body. A lot of researches are going on worldwide directed towards finding natural antioxidants of plants origins. The aims of this study were to evaluate in vitro antioxidant activities and to

Although orthodox medications are available for skin diseases, expensive dermatological services have necessitated the use of medicinal plants as a cheaper alternative. This study evaluated the pharmacological and phytochemical profiles of four medicinal plants (Drimia sanguinea,
