Three new iridoids, 10-deacetyl suspensolide A aglycone (1), 7-deacetyl suspensolide A aglycone (2), and 7,10-dideacetyl suspensolide A aglycone (3), were isolated from two species of Viburnum. Their structures were elucidated on the basis of spectroscopic methods, including 1D and 2D NMR
Recent studies demonstrated that the proanthocyanidins (PA), the polymers of flavan-3-ols, naturally occurring plant metabolites widely available in fruits, vegetables, nuts, seeds, flowers and bark, have anti-inflammatory, anticarcinogenic, anti-allergic, antioxidant and vasodilatory actions. We
Three new neolignans, fordianoles A-C (1-3), characterized as (7S,8R)-4-hydroxy-3,3',5'-trimethoxy-8',9'-dinor-8,4'-oxyneolignan-7,7',9-triol, (7R,8R)-4-hydroxy-3,3',5'-trimethoxy-8',9'-dinor-8,4'-oxyneolignan-7,7',9-triol, and
Viburnum opulus (VO) is a valuable decorative, medicinal, and food plant. This deciduous shrub is found in natural habitats in Europe, Russia, and some regions in North Africa and North Asia. The VO is traditionally used to treat aliments such as cough, colds, tuberculosis, rheumatic aches,
OBJECTIVE
The purpose of the study was to assess the anti-inflammatory effects of the mushroom Inonotus obliquus (Chaga), Polygala senega (Senega) and Viburnum trilobum (Cranberry) bark extract fractions from locally produced materials in lipopolysaccharide (LPS) induced murine macrophage RAW 164.7
Nine new neolignan glycosides (1-9), viburfordosides A-I, two new neolignans, fordianes A and B (10, 11), and seven known analogues (12-18) have been isolated and identified from the fruits of Viburnum fordiae Hance. The structures and absolute configurations of undescribed neolignan constituents
A green, rapid and cost effective method for the bio-synthesis of silver nanoparticles (AgNPs), using polyphenols present in European cranberry bush fruit extracts was developed. The obtained AgNPs were characterized by ultra-violet visible spectroscopy (UV-VIS), Fourier transform - infrared
Viburnum pichinchense Benth. Mainly found in Ecuador and Colombia has been ethnopharmacologically utilized as a remedy for various female disorders with kidney inflammation and uterine relaxant.The pharmacological activity of Viburnum pichinchense has never A new lignan, (7'S,8S,8'S)-3,5'-dimethoxy-3',4,9'-trihydroxy-7',9-epoxy-8,8'-lignan, named vibruresinol (1), was isolated from the stems of Viburnum erosum by silica gel, ODS, and Sephadex LH-20 column chromatography. In addition, four other known lignans,
The main purpose of the present paper is to emphasize the non-invasive effect of some new prepared nanomaterials on skin diseases (psoriasis) together with the procedures to obtain them. These new materials are based on gold nanoparticles and natural compounds extracted from native plants of the
Since nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) has been found to be involved in various pathophysiological processes, including inflammation and carcinogenesis, the modulators of NO synthesis or expression have been considered as potential anti-inflammatory and cancer
