Ethanol extract of Bletilla striata has remarkable anti-inflammatory and anti-pulmonary fibrosis activities in the rat silicosis model. However, its active substances and molecular mechanism are still unclear. To uncover the active ingredients and potential molecular mechanism of the
Nine new phenanthrenes (1-9) and a new benzyl glycoside (10) together with 45 known compounds were isolated from the rhizomes of Bletilla formosana. The structures of 1-10 were elucidated primarily on the basis of their 1D and 2D NMR spectroscopic data. Most of the isolated compounds were evaluated
BACKGROUND
Bletilla striata is a traditional Chinese medicine used to treat hemorrhage, scald, gastric ulcer, pulmonary diseases and
inflammations. In this study, we investigated bioactivity of the effective fraction of B. striata (EFB) in reducing the inflammatory cytokine
Four new spirostane steroidal saponins, (1α,3α)-1-O-[(β-d-xylopyranosyl-(1→2)-α-l-rhamnopyranosyl)]-3-O-d-glucopyranosyl-5α-spirostan (1), (1α,3α)-1-O-[(β-d-xylopyranosyl-(1→2)-α-l-rhamnopyranosyl)oxy]-3-O-d-glucopyranosyl-25(27)-ene-5α-spirostan (2),
In the current study, we analyzed the functions and mechanisms of Bletilla striata polysaccharide b (BSPb) against Angiotensin II (Ang II)-induced oxidative stress and inflammation in human mesangial cells (HMCs). It was found that BSPb could inhibit generation of Ang II-induced reactive oxygen
Dry eye syndrome (DES) is a multifactorial disorder of the ocular surface affecting many people all over the world. However, there have been many therapeutic advancements for the treatment of DES, substantial long-term treatment remains a challenge. Natural plant-based polysaccharides have gained
Four new dihydrophenanthrenofuran, bleochranols A-D (1-4), along with 21 known compounds including phenanthrenes (5-14) and bibenzyls (15-25) were isolated and elucidated from the rhizomes of Bletilla ochracea. Combination of 1D/2D NMR techniques and the Electronic Circular Dichroism (ECD)
Ten previously undescribed stilbenoids, including six bibenzyls (bleochrins A-F, 1-6), three phenanthrenes derivatives (bleochrins G-J, 7-10) along with eleven known compounds were isolated from the rhizomes of Bletilla ochracea Schltr. The structural characterizations of 1-21 were accomplished by
As traditional Chinese medicine, Bletilla striata has been widely applied to clinical treatment for its unique pharmacological profiles. This study aimed to investigate the beneficial role of Bletilla striata oligosaccharides (BO) in improving the metabolic syndrome by regulation of gut microbiota
The aim of this study was to evaluate the efficacy of Bletilla striata polysaccharide on diabetes mellitus ulcers. Diabetes mellitus animal model was established by single ip injection of streptozotocin (STZ, 50 mg x kg(-1)) with the criteria of blood glucose > or = 16.7 mmol x L(-1) after 72 h. 4
When the skin is injured, the subcutaneous tissues and organs are threatened by pathogens and excessive water loss. Wound dressings are, therefore, needed to protect the wound site from infection and improve the wound closure. Natural polysaccharides have been applied for various biomaterials
Postoperative peritoneal adhesions (PPAs) constitute a common complication of abdominal surgery with a high incidence. Bletilla striata (BS) is an important hemostatic drug used in China for nearly 2000 years. The purpose of this study was to investigate the effect of Bletilla striata
OBJECTIVE
To evaluate the safety of intracameral and subconjunctival injection of a novel mucoadhesive polysaccharide isolated from Bletilla striata in rabbit eye.
METHODS
One hundred microliters (100 μL) of Bletilla striata polysaccharide (BsP) at concentrations of 10, 40, and 80 mg/mL was
We have prepared Chinese traditional herb Bletilla striata into microspheres as a novel embolic agent for decades. The aim of this study was to evaluate the biocompatibility of Bletilla striata microspheres (BSMs). After a thermal test of BSMs in vitro, the cell biocompatibility of BSMs was
This study was carried out to investigate the effect of Bletilla striata polysaccharide (BSP) treating on lipopolysaccharide (LPS)-induced intestinal epithelial barrier disruption in rat intestinal epithelial cell (IEC) line.LPS was used to stimulate the
