In this work we investigated the antitussive activity of the medicinal tree Terminalia arjuna. We used the stem bark for extraction and preparation of water extracted isolate and its two fractions: acetone-soluble (TA-S) and acetone precipitated (TA-P) fraction. The presence of a pectic
Piper nigrum L. fruits are not only a prized spice, but also highly valued therapeutic agent that heals many ailments including asthma, cold and respiratory problems. Herein, we have investigated structural features and in vivo antitussive activity of three fractions isolated from Piper nigrum
Root extracts of the medicinal plant Pelargonium sidoides, native to South Africa, are used globally for the treatment of common cold and cough. Due to an increasing economic commercialization of P. sidoides remedies, wild collections of root material should be accompanied by effective methods for
Traditional Indian medicines have been used in humans for thousands of years. While the link to a particular indication has been established in man, the active principle of the formulations often remains unknown. In this study, we aim to investigate the structural features and antitussive activity
A low molecular mass arabinogalactan-protein (AGP) composed of galactose and arabinose with a low protein content, isolated from the instant coffee powder of Coffea arabica beans, has been tested on antitussive (in vivo) and immunomodulating (ex vivo) activities. The results of antitussive tests
BACKGROUND
Solanum virginianum L. is used for the management of fever, bronchial asthma and cough for thousands of years. While the link to a particular indication has been established in human, the active principle of the formulation remains unknown. Herein, we have investigated a polysaccharide
Terminalia chebula, a medicinal plant, is widely used in the management of various diseases. As the water extract of its dried ripe fruit is a frequently used preparation, we decided to look for bioactive polysaccharide in this extract. We demonstrate that the obtained polysaccharide fraction, CP,
The extraction of Fallopia sachalinensis leaves resulted in two fractions (FS-1 and FS-2). Chemical and spectral analyses of samples revealed the prevalence of pectic polysaccharides with high galacturonic acid, arabinose, galactose, and rhamnose content. Arabinogalactan with a higher content of
Polyphenolic-polysaccharide-protein complex has been isolated from flowers of Solidago canadensis L. by hot alkaline extraction procedure. Compositional analyses of S canadensis complex revealed the presence of carbohydrates (43 wt%), protein (27 wt%), phenolics (12 wt%), uronic acids (10 wt%) and
A high molecular mass polysaccharide-polyphenolic conjugate has been isolated from flowering parts of Lythrum salicaria by hot alkaline extraction. Its chemical analysis revealed 74% of carbohydrates and 17% of phenolics. Compositional analysis of carbohydrate part showed a high GalA content (49%),
Arabinogalactan is a polysaccharide isolated from the roots of the medicinal plant Withania somnifera L. It contains 65% arabinose and 18% galactose. The aim of the present study was to evaluate the antitussive activity of arabinogalactan in conscious, healthy adult guinea pigs and the role of the
OBJECTIVE
Anti-tussive drugs are amongst the most widely used medications worldwide; however no new class of drugs has been introduced into the market for many years. The present study aims at evaluating the structural features and in vivo anti-tussive activity of a polysaccharide fraction from
BACKGROUND
Water decoctions of the root bark, stem bark and leaves of Terminalia macroptera are used by traditional healers in Mali to cure a wide range of illnesses, such as wounds, hepatitis, malaria, fever, cough and diarrhea as well as tuberculosis. Plant polysaccharides isolated from crude
A dark brown polymeric complex was isolated from flowering parts of medicinal plant Arnica montana L. by hot alkaline extraction followed by neutralization and multi-step extractions with organic solvents. It was recovered in 5.7% yield, on GPC showed two peaks of molecular mass of 9 and 3.5kDa. The
From the leaves of popular Malian medicinal plants Trichilia emetica (TE) and Opilia celtidifolia (OC), and fruits of Crossopteryx febrifuga (CF) water and water-ethanol soluble polysaccharide materials were isolated. The results of chemical analysis of the crude polysaccharides showed the dominance
