A novel glucoside bletilloside A (1) was isolated from the tubers of Bletilla striata, together with seven known compounds (2-8). Their structures were determined on the basis of extensive spectroscopic analyses. All compounds were evaluated for the inhibition on NO production effects in RAW 264.7 macrophage cells, while militarine (4) and dactylorhin A (5) exhibited moderate inhibitory effects.

The emergence of antimicrobial resistance poses significant challenges in conventional antibiotic treatments for chronic wound infections, highlighting an urgent need for alternative therapeutic strategies. To address this issue, we developed a multifunctional electrospun nanofiber dressing co-loaded with anthocyanin (ATH) and asiaticoside (AS) that possesses antimicrobial activity. The tri-layer dressing contains three functional components: a hydrophilic polyacrylonitrile-anthocyanin (PAN-ATH) layer for pH monitoring, a hydrophobic polycaprolactone (PCL) layer for exudate management, and a water-soluble pullulan-Bletilla striata polysaccharide-asiaticoside (PUL-BSP-AS) layer.

Wound healing is often hindered by bacterial infection, oxidative stress, and bleeding. Traditional dressings cannot simultaneously regulate multiple microenvironments. To address the shortcomings of traditional dressings, this study constructed a dual-network photothermal responsive multifunctional hydrogel OBCTCu based on four natural ingredients, including Bletilla striata polysaccharide (BSP), chitosan (CS), tannic acid (TA), and Cu.

Bioactive substance-integrated hydrogels have demonstrated efficacy in diabetic wound treatment. However, challenges remain in identifying naturally derived, multifunctional active substances capable of addressing the complex pathophysiology of wounds, as well as in tailoring hydrogels to enhance their suitability for wound applications. Here, we present a novel biological hydrogel microcarrier system by integrating Bletilla striata-derived nanoparticles (PdNPs) and polydopamine nanozymes (PDAs) into a hyaluronic acid-methacrylate (HAMA) hydrogel.

We assessed the genetic diversity and population structure of the protected orchid across 18 wild populations in southwestern China. Eight pairs of simple sequence repeat (SSR) molecular markers were employed for its genetic diversity and population structure analyses, while the optimized Maxent model was utilized to predict changes in the habitat distribution under historical conditions and three future climate scenarios (SSP126, SSP245, and SSP585) with 141 natural distribution data and 19 climatic factors. The results revealed an average number of alleles () of 3.
