Acetylation and Silylation of Piperidine Solubilized Sporopollenin from Pollen of Typha angustifolia L.

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2003
Abstract Silyl and acetyl derivatives of sporopollenin from the pollen of Typha angustifolia L. were prepared. The derivatized products were readily soluble in piperidine-d11 and could be investigated employing one- and two-dimensional proton and carbon NMR (nuclear magnetic resonance) spectroscopy (1H,1H-COSY and 13C,1H-HETCOR ...

Thermogravimetric study on typha (Typha angustifolia L.)

Journal of Thermal Analysis, 1989
Thermogravimetric analysis, was employed to study the thermal behaviour of typha, a naturally growing plant in the marshes of the south of Iraq, and its main components, holocellulose, hemicellulose and cellulose. The overall TG signal of typha appeared as the sum of those of hemicellulose and cellulose.

Streptomyces typhae sp. nov., a novel endophytic actinomycete with antifungal activity isolated the root of cattail (Typha angustifolia L.)

Antonie van Leeuwenhoek, 2021
A novel endophytic actinomycete with antagonistic activity against various phytopathogenic fungi, designated strain p1417T, was isolated from the root of cattail (Typha angustifolia L.) collected from Yunnan Province, Southwest China. A polyphasic taxonomic study was carried out to establish the taxonomic status of this strain.

Mechanisms of cadmium detoxification in cattail (Typha angustifolia L.)

Aquatic Botany, 2011
Abstract Cadmium (Cd) is a widespread heavy metal pollutant and environmental and human health hazard, which may be partially resolved using green and cost-effective phytoremediation techniques. However, the efficiency of phytoremediation is often limited by the small biomass of Cd-hyperaccumulator plants.

Benthic macroinvertebrate response to sedimentation in a Typha angustifolia L. wetland

Wetlands Ecology and Management, 2001
Fiberglass mesh enclosures (1 × 1 m2) in a Typha angustifoliaL. marsh were employed to examine the effects of clay additions on theresident macroinvertebrate communities. Total invertebrate density, insectdensity, and number of insect families decreased significantly by 33%,37%, and 17%, respectively, in enclosures receiving sediment. Morespecifically,

Internal gas transport in Typha latifolia L. and Typha angustifolia L. 2. Convective throughflow pathways and ecological significance

Aquatic Botany, 1994
Abstract The gas flow pathways within Typha latifolia L. and Typha angustifolia L. were evaluated by studying the internal pressurization and convective flow through individual leaves and the internal resistances to gas flow within the plants. Air enters the middle-aged leaves against a small pressure gradient by humidity-induced pressurization ...

Structural determination and pro-angiogenic effect of polysaccharide from the pollen of Typha angustifolia L.

International Journal of Biological Macromolecules, 2022
Four fractions of polysaccharides (TPP-1, TPP-2, TPP-3, and TPP-4) were isolated and purified from the pollen of Typha angustifolia L., and the structure of TPP-3 was furtherly determined by HPGPC (High Performance Gel Permeation Chromatography), monosaccharide composition analysis, methylation analysis and NMR (Nuclear Magnetic Resonance).
