dendrobium catenatum/inflammation

The stems of Dendrobium moniliforme have been used in traditional herbal medicine for the treatment of fever and lack of body fluid in Korea. In this study, we investigated anti-inflammatory effects of the aqueous extract of D. moniliforme stems (DM) in response to lipoteichoic acid (LTA), a major

Dendrobium officinale stem is rich in polysaccharides, which play a great role in the medicinal effects of this plant. However, little was known about the polysaccharides from Dendrobium officinale leaves. Two kinds of polysaccharides in the leaves, DLP-1 and DLP-2, were obtained by hot water

Cultivated Dendrobium denneanum has been substituted for other endangered Dendrobium species in recent years, but there have been few studies regarding either its chemical constituents or pharmacological effects. In this study, three phenanthrene glycosides, three 9,10-dihydrophenanthrenes, two

BACKGROUND D. macrostachyum is an epiphytic orchid abundant in Southern India and is reported for pain relief in folklore. OBJECTIVE The objective of the present study was to determine in vitro free radical scavenging and anti-inflammatory activity of D. macrostachyum and to perform LCMS based

A pair of racemic indolizidine enantiomers, (±)-homocrepidine A (1), and a piperidine derivative, homocrepidine B (2), were isolated from Dendrobium crepidatum along with the known alkaloid crepidine (3). The racemic mixture of 1 was separated into a pair of enantiomers, (+)-1 and (-)-1, by HPLC

Dendrobium nobile belongs to the Orchidaceae family and is one of the medicinal herbs used in traditional Chinese medicine as a therapeutic agent for gastrointestinal and cardiovascular diseases. In this study, we separated three phenanthrenes (ephemeranthol A (EA), 1,5,7-trimethoxyphenanthren-2-ol

Previous studies of Dendrobium candidum (D. candidum), which is mainly distributed in tropical areas, have mainly focused on its functional polysaccharide; the effects of D. candidum polyphenols, the chemical composition of which may be improved by fermentation, have received

Dendrobium is a traditional Chinese herb with anti-diabetic effects and has diverse bibenzyls as well as phenanthrenes. Little is known about Dendrobium polyphenols anti-diabetic activities, so, a rich-polyphenols extract of D. loddigesii (DJP) was used for treatment of diabetic

The aim of this study was to explore the therapeutic effect and underling mechanism of Dendrobium officinale polysaccharides (DOPS) on two well-established animal models of learning and memory disabilities. Model of estrogen deficiency caused learning and memory disability can be induced by

Sjögren's syndrome (SS) is a chronic autoimmune disease with exocrine glands disorder. Our previous work demonstrated the protective effect of Dendrobium officinale polysaccharides (DP) both on the phenotypes of patients and animal model with SS. In this study, we expand these observations to

Diabetic retinopathy (DR) is a serious complication of diabetes mellitus. This study aimed to observe the alleviation of the ethanol extract of Dendrobium chrysotoxum Lindl. (DC), a traditional Chinese herbal medicine, on DR and its engaged mechanism. After DC (30 or 300 mg/kg) was orally

Dendrobium officinale Kimura et Migo (Dendrobium catenatum Lindley), a prized traditional Chinese Medicine, has been used in China and Southeast Asian countries for centuries. The present study was aimed to investigate the effects and the possible mechanisms of the Dendrobium officinale extracts

Blood-retinal barrier (BRB) breakdown is a typical event in the early stage of diabetic retinopathy (DR). This study aims to elucidate the protection of erianin, a natural compound isolated from Dendrobium chrysotoxum Lindl, against DR development. Erianin alleviated BRB breakdown and rescued

The present work investigated the inhibitory activity of the polysaccharide from cultivated Dendrobium huoshanense (cDHP) on lung inflammation in cigarette smoke (CS)-induced mouse model. cDHP was mainly composed of mannose and glucose in a molar ratio of 1.89: 1.00, and had a backbone with linkages

Six pairs of octahydroindolizine-type alkaloid enantiomers (1-6) including three new compounds [(-)-1/(+)-1, 2] were isolated from the stems of Dendrobium crepidatum. Their structures including the absolute configurations were elucidated by extensive spectroscopic analyses and comparison between the
