Elm fruits were once an important food source in the years of famine. Research on the functional compounds in elm fruits was almost unavailable. In this study, we established an efficient high-performance liquid chromatography method for the simultaneous separation of eight chlorogenic acids and 28

The present study was carried out to determine the effects of selenylation on structural and antioxidant activities of pectic polysaccharides extracted from Ulmus pumila L. (PPU). Selenylation of PPU (Se-PPU) was synthesized by different concentrations of sodium selenites (0.2, 0.4, 0.6, 0.8, and

BACKGROUND Herbal remedies used by patients for treatment of inflammatory bowel disease include slippery elm, fenugreek, devil's claw, Mexican yam, tormentil and wei tong ning, a traditional Chinese medicine. Reactive oxygen metabolites produced by inflamed colonic mucosa may be pathogenic.

In this study, a comparative liquid chromatography/mass spectroscopy (LC/ESI-MS/MS) profiling of different fractions of Ulmus parvifolia leaves and stems was performed. Identification of compounds was based on comparing the mass spectrometric information obtained including m/z values and individual

The roots of Ulmus macrocarpa Hance (Ulmaceae) have been used as an oriental traditional medicine for the treatment of inflammation, ulcers, cancers, and parasites. Activity guided isolation from the roots of U. macrocarpa yielded three flavonoids [catechin 7-O-β-D-apiofuranoside (1), (+)-catechin

The glycoprotein isolated from Ulmus davidiana Nakai (UDN) (UDN glycoprotein) has a molecular weight of 116 kDa and consists of 78.65% carbohydrate content and 21.35% protein content. In the present study, we investigated the hypolipidemic effect of UDN glycoprotein on Triton WR-1339-induced mice.

The present study was performed to evaluate the cardiovascular effects of ethanolic extract from the root bark of Ulmus macrocarpa (RBUM) in rats. The effects of RBUM on the vascular response of isolated rat aorta and the blood pressure of spontaneously hypertensive rats (SHRs) were evaluated. In

To protect from reactive oxygen species (ROS) damages, skin cells have evolved to have antioxidant enzymes, such as copper and zinc-dependent superoxide dismutase (SOD1), mitochondrial manganese-dependent superoxide dismutase (SOD2), catalase (CAT), glutathione peroxidase (GPX), and glutathione

Gall formation is induced by an insect, which changes normal plant development and results in the formation of a new organ, following distinct stages of metabolic and developmental alterations. Research on mechanisms of recognition and responses to biotic stress may help to understand the

Climate change and global migrations of people and goods have exposed trees to new diseases and abiotic challenges that threaten the survival of species. In vitro germplasm storage via cryopreservation is an effective tool to ensure conservation of tree species, but plant cells and tissues are

Three new sesquiterpene ortho-naphthoquinones, davidianones A, B and C, together with four known compounds, mansonones E, F, H and I, were isolated from the root bark of Ulmus davidiana. On the basis of spectral data including pulse field gradient two-dimensional NMR spectroscopy, the structures of

A methanolic (MeOH) extract of Ulmus davidiana was analyzed for antioxidant activity using model systems, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, hydroxyl radical (OH) scavenging, reducing power, and total phenolic content. The MeOH extract exhibited strong antioxidant

Glycoprotein of Ulmus davidiana Nakai (UDN glycoprotein) was isolated and identified using SDS-PAGE. UDN glycoprotein was shown to have strong scavenging activities against oxygen free radicals, as detected by different oxygen-radical formation assays. To investigate the anti-apoptotic effects of

Previous studies have shown that controlled deterioration treatment (CDT) induces programmed cell death in elm (Ulmus pumila L.) seeds, which undergo certain fundamental processes that are comparable to apoptosis in animals. In this study, the essential characteristics of mitochondrial physiology in

BACKGROUND The plant Ulmus wallichiana Planch. is found in hills of Uttarakhand, India. Bark of U. wallichiana is commonly used as traditional healer for bone fracture of animals as well as human beings and also used as wound healer remedy. OBJECTIVE The present study was designed to evaluate
