To optimize the extraction process of crude polysaccharides from Atractylodes and elaborate the mechanism of Atractylodes polysaccharides in treating diarrhea owing to spleen deficiency, so as to lay a foundation for further development and utilization of Atractylodes lancea, we used an orthogonal test to optimize the extraction process and established a model of spleen deficiency. It was further combined with histopathology and intestinal flora to elaborate the mechanism of Atractylodes polysaccharides in the treatment of spleen-deficiency diarrhea. The optimized extraction conditions were as follows: the ratio of material to liquid was 1:25; the rotational speed was 150 rpm; the extraction temperature was 60°C; the extraction time was 2 h; and the extraction rate was about 23%.

Scar-free wound healing is a challenging process due to the excessive deposition of extracellular matrix and collagen. To overcome this issue, hydrogels with superior biochemical and mechanical properties have been used in combination with medicinal compounds as wound dressings. In this study, a novel composite hydrogel consisting of double-crosslinked photocurable hyaluronic acid methacrylate (HAMA) and Laponite (Lap) loaded with bioactive bone morphogenetic protein 4 (BMP4) was developed and thoroughly characterized for its properties such as degradation, morphology, porosity, compression, skin adhesion and load release.

This study compared the transcriptome of Atractylodes lancea rhizome at different development stages and explored genes encoding the key enzymes of the sesquiterpenoid biosynthesis pathway. Specifically, Illumina NovaSeq 6000 was employed for sequencing the cDNA libraries of A. lancea rhizome samples at the growth stage(SZ), flowering stage(KH), and harvesting stage(CS), respectively.

The effective material basis of Chinese medicine is the key and difficult point in the quality control and modernization research of Chinese medicine. With the increasing application of pharmacophore-based virtual screening in computer-aided drug design, it is possible to employ this technology in the modernization of Chinese medicine. Based on the systematic research method of the pharmacophore model, the present study systematically reviewed the pharmacophore-based technologies and strategies in the identification of active components in Chinese medicine.

Article Synopsis
  • Atractylodis Rhizoma (AR) is a traditional Chinese medicinal resource known for its health benefits, including eliminating dampness, strengthening the spleen, and aiding digestion.
  • ARP, a key non-volatile component of AR, demonstrates various biological activities like immunomodulation, anti-tumor, anti-viral, and antioxidant effects, making it a subject of research interest.
  • Current studies on ARP focus on extraction, purification, structural analysis, and biological activity, but there are still many gaps in knowledge that need to be addressed for more comprehensive understanding and application.
