One new bibenzyl (1) and one new phenanthrene (2), together with two known bibenzyls (3-4) and four known diarylheptanoids (5-8) were isolated from the rhizomes of Dioscorea zingiberensis. The structures of 1-2 were elucidated by spectroscopic methods including 1D and 2D NMR. Phenols 1-8 were
Acute pancreatitis (AP) is a painful inflammatory disorder of the exocrine pancreas, ranking as the most common gastrointestinal reasons for hospitalization with no specific therapy currently. Diosgenyl saponins extracted from natural products and diosgenin or its derivatives have been shown to
Following a short treatment for irritable bowel with the following herbs: Astragalus propinquus, Codonopsis pilosula, Paeonia sp., Atractylodes macrocephala, Pueraria sp., Poria cocos, Dioscorea opposita, Patriniae, Psoralea corylifolia, Alpinia katsumadai, Glycyrrhiza uralensis and Dolomiaea
The bioactive polysaccharides (named ZPF1) from yam ( Dioscorea batatas) were chemically determined, suggesting repeating beta-1,4-mannan as mainly having a feature of acetylation on C2-OH and C3-OH, around 28%. The ZPF1 participated in the stimulation of murine wild-type macrophages predominantly
The complete genome sequence of a novel member of the genus Macluravirus was determined from yam plants with chlorotic and necrotic symptoms in China. The genomic RNA consists of 8,261 nucleotides (nt) excluding the 3'-terminal poly(A) tail, containing one long open reading frame (ORF) encoding a
Rhizoma Dioscorea bulbifera, the tuber of Dioscorea bulbifera L., has been used to treat various diseases. However, the clinical application has been limited for its hepatotoxicity. In this study, we explored the cascade working mechanisms of time-dependent hepatotoxicity induced by total saponins
OBJECTIVE
To study the pathological change and the toxic mechanism of Dioscorea bulbifera L in mice.
METHODS
Sixty ICR mice were randomly assigned to four groups poisoned respectively with 200% Dioscorea bulbifera L of 1/4 LD50, 1/10LD50, 1/30LD50 and a control group treated with distilled water by
Dioscorea opposita is an edible and medicinal plant available in many areas of China. This study aimed to assess in vitro immune potentials of a water-soluble polysaccharide extract from D. opposita planted in Henan Province, China. In vitro effects of the extract on three immune cells (macrophages,
Atherosclerosis is a chronic inflammatory disease, which is associated with increased expression of adhesion molecules and monocyte recruitment into the arterial wall. This study evaluated whether hexane extracts from the edible part (DB-H1) or bark region (DB-H2) of Dioscorea. batatas Decne have
Dioscoreae Rhizoma (MDR), the root of Dioscorea tokoro MAKINO, has been used for the treatment of arthritis, muscular pain and urinary diseases in oriental medicine. The present work evaluates a methanol extract of Dioscoreae Rhizoma (MDR). MDR did not show any cytotoxic effect on mouse lung
Airpotato yam is a traditional Chinese medicine used for treating thyroid disease and cancer in China. Diosbulbin B (DB) is reported to be the main hepatotoxic compound isolated from Airpotato yam. A variety of reports have shown the acute liver injury induced by DB in vivo. However, whether
It has been reported that DA-9801, an extract mixture of Dioscorea japonica Thunb and Dioscorea nipponica Makino, produces a neurotrophic activity. Therefore, this study was conducted to examine the neuroprotective effects of DA-9801 in streptozotocin-induced diabetic rats. The experimental rats
Diosbulbin B (DIOB), a furanoid, is a major constituent of herbal medicine Dioscorea bulbifera L. Exposure to DIOB caused liver injury in humans and experimental animals. The mechanisms of DIOB-induced hepatotoxicities remain unknown. The present study demonstrated that DIOB induced hepatotoxicities
Dioscorealide B (DB), a naphthofuranoxepin has been purified from an ethanolic extract of the rhizome of Dioscorea membranacea Pierre ex Prain & Burkill which has been used to treat inflammation and cancer in Thai Traditional Medicine. Previously, DB has been reported to have anti-inflammatory
