Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...

BACKGROUND AND AIMS Helichrysum bracteatum is called an 'eternal flower' and has large, coloured, scarious bracts. These maintain their aesthetic value without wilting or discoloration for many years. There have been no research studies of cell death or cell morphology of the scarious bract, and hence the aim of this work was to elucidate these characteristics for the bract of H. bracteatum. ...

objective(s):ethnopharmacological field surveys demonstrated that many plants, such as gentiana olivieri, helichrysum graveolens, helichrysum plicatum ssp. plicatum, juniperus oxycedrus ssp. oxycedrus, juniperus  communis var. saxatilis, viscum album (ssp. album, ssp. austriacum), are used as traditional medicine for diabetes in different regions of anatolia. the present study was designed to e...

The effect of combinations of the crude methanolic extract of the leaves of Helichrysum pedunculatum and eight first-line antibiotics were investigated by time kill assays against a panel of bacterial strains that have been implicated in wound infections. The plant extract showed appreciable antibacterial activities against the test bacteria with zones of inhibition ranging between 18 and 27 mm...

In the present study, lectotypes for 12 names viz. Anaphalis beddomei Hook.f., bournei Fyson, elliptica DC., oblonga var. lawii meeboldii W.W.Sm., travancorica Gnaphalium marcescens Wight, neelgherryanum subdecurrens wightianum DC. and Helichrysum leptophyllum are designated. Detailed notes images of type specimens provided.

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 phenolic contents of the extract. The extract exhibited scavenging activity towards all radicals t...
