Article Abstract
Plant polysaccharides, distinguished by diverse glycosidic bonds and various cyclic sugar units, constitute a subclass of primary metabolites ubiquitously found in nature. Contrary to common understanding, plant polysaccharides typically form hydrocolloids upon dissolution in water, even though both excessively high and low temperatures impede this process. Bletilla striata polysaccharides (BSP), chosen for this kinetic study due to their regular repeating units, help elucidate the relationship between polysaccharide gelation and temperature. It is suggested that elevated temperatures enhance the mobility of BSP molecular chains, resulting in a notable acceleration of hydrogen bond breakage between BSP and water molecules and consequently, compromising the conformational stability of BSPs to some extent. This study unveils the unique relationship between polysaccharide dissolution processes and temperature from a kinetics perspective. Consequently, the conclusion provides a dynamical basis for comprehending the extraction and preparation of natural plant polysaccharide hydrocolloids, pharmaceuticals and related fields.

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.
