Flavonol glycosides from Pteridium aquilinum

Phytochemistry, 1995
Abstract Two new flavonol glycosides from aerial parts of Pteridium aquilinum were identified as quercetin 3- O - β -laminaribioside and isorhamnetin 3- o - β -laminaribioside by chemical and spectroscopic methods.

Dihydrocinnamic acids in Pteridium aquilinum

Food Chemistry, 2005
Abstract Dihydro-p-coumaric (phloretic) and dihydroferulic acids have been identified in Pteridium aquilinum. Whereas the latter has been located in cyanogenic and acyanogenic plants, the first has only been detected in cyanogenic forms.

Aquilinan, an acidic polysaccharide from Pteridium aquilinum

Phytochemistry, 1976
Abstract A water-soluble, acidic polysaccharide, aquilinan, was isolated from storage rhizomes and young fronds of bracken and shown to be homogeneous. The polysaccharide contained galactose, xylose, fucose and arabinose residues together with chains of repeating α(1-2′)glucuronosylmannose units.

Extracellular polysaccharides from Pteridium aquilinum suspension cultures

Phytochemistry, 1990
Abstract Extracellular polysaccharides were isolated from the medium of liquid suspension cultures of bracken (Pteridium aquilinum) L. Kuhn var. latiusculum (Desv.) Underw. The resulting material contained very few charged pectic polysaccharides. Glycosyl composition and linkage analysis showed that the major polysaccharide components were a large ...

Phylloplane mycoflora of bracken, Pteridium aquilinum

Transactions of the British Mycological Society, 1974
The phylloplane mycoflora on the fronds of bracken, Pteridium aquilinum , was followed during two seasons and was shown to be similar to that on angiosperm leaves. The succession involved Aureobasidium pullulans, Botrytis cinerea and Clado-sporium herbarum followed by Alternaria alternata and Epicoccum purpurascens .

The movements of spermatozoa of bracken (Pteridium aquilinum)

Experimental Cell Research, 1954
Abstract 1. 1. The movement of bracken sperms in tap water is random, the mean square displacement being proportional to the time. 2. 2. It is known that when sperms arrive at the mucilage at the necks of mature archegonia they become immobilised; it has been found in the present work that this immobilisation is irreversible. 3. 3. Sperms

Preparation and antioxidant activity of Pteridium aquilinum-derived oligosaccharide

International Journal of Biological Macromolecules, 2013
In this study, Pteridium aquilinum-derived oligosaccharides (PAO) were prepared from Pteridium aquilinum polysaccharides by hydrolysis using hydrogen peroxide and their hydroxyl radical scavenging activity was investigated. The hydrolysis process was monitored by the yield of PAO.
