The chemical constituents of Huanglian Decoction were determined via the advanced ultra-performance liquid chromatography-quadrupole-time-of-flight-tandem mass spectrometry (UPLC-Q-TOF-MS/MS) technique. Gradient elution was executed on an Agilent ZORBAX Extend-C18 column (21 mm × 100 mm, 18 µm) using a binary mobile phase comprised of 0.1% formic acid aqueous solution (A) and acetonitrile (B). The flow rate was 0.3 mL/min and the column temperature was maintained at 35°C. Electrospray ionization (ESI), both positive and negative modes, was employed by the MS instrument, and mass spectra were acquired across a m/z range of 100 to 1500. Through the combination of high-resolution mass spectrometry data analysis, comparative literature examination, and reference confirmation, this study determined the presence of 134 chemical components in Huanglian Decoction. This encompassed 12 alkaloids, 23 flavonoids, 22 terpenes and saponins, 12 phenols, 7 coumarins, 12 amino acids, 23 organic acids, and 23 other compounds, with their respective medicinal origins detailed. Based on the findings of previous studies, seven components were designated as index components. Utilizing network pharmacology research approaches and STRING 110 database resources, intersectional target protein-protein interaction (PPI) network information was extracted, leading to the identification of 20 core efficacy targets. UPLC-Q-TOF-MS/MS analysis successfully revealed the chemical components of Huanglian Decoction, and network pharmacology highlighted its core efficacy targets. This comprehensive approach laid the groundwork for elucidating the material basis and quality control of the decoction.

The classical prescription Huoluo Xiaoling Dan is commonly administered in clinical settings to effectively address pain and enhance blood circulation. This research focused on improving lesion treatment and outcome through the optimization of the Huoluo Xiaoling gel paste preparation method. The in vitro transdermal absorption of the gel was then assessed, providing a scientific foundation for its development and practical application. caecal microbiota Using primary viscosity, holding viscosity, and sensory score as evaluation criteria, the gel paste's matrix amount was determined through a single-factor experiment and a Box-Behnken response surface design. A UPLC method was developed for quantifying eight active constituents: Danshensu, ferulic acid, salvianolic acid B, salvianolic acid A, ligustilide, tanshinone A, 11-keto-boswellic acid (KBA), and 3-acetyl-11-keto-boswellic acid (AKBA). By utilizing a modified Franz diffusion cell method, a comprehensive evaluation and comparison of the absorption properties of gel paste, incorporating or excluding volatile oil microemulsion, were undertaken. The study's findings establish that the optimal formulation for Huoluo Xiaoling gel paste matrix incorporates NP700 (135 g), glycerol (700 g), micropowder silica gel (125 g), sodium carboxymethyl cellulose (20 g), tartaric acid (6 g), and glyceryl aluminum (4 g). A study of the paste's composition revealed the eight active ingredients had mass fractions of 0.048, 0.0014, 0.095, 0.039, 0.057, 0.0055, 0.035, and 0.097 milligrams per gram. The in vitro transdermal absorption study results showed that the addition of volatile oil or its microemulsion formulation improved the absorption of active components, exhibiting compliance with the zero-order or Higuchi equation. Following the optimal prescription, the prepared gel paste possesses an attractive appearance and firm adhesion, with no residual material, and exhibits the characteristics of a skeletal slow-release preparation. This facilitates reduced administration frequency, forming the foundation for new external dosage forms of Huoluo Xiaoling Dan.

Northeastern China is home to one of its Dao-di herbs, Eleutherococcus senticosus. Three samples of E. senticosus from different authentic producing areas were used in this study for sequencing their chloroplast genomes, which were then analyzed for specific DNA barcodes. A scrutiny of the germplasm resources and genetic diversity of E. senticosus was conducted, employing specific DNA barcodes. In specimens of *E. senticosus*, from different legitimate producing regions, the total length of their chloroplast genomes measured from 156,779 to 156,781 base pairs, and displayed a canonical tetrad organization. Within every chloroplast genome, the total gene count reached 132, including 87 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. Chloroplast genomes displayed remarkable stability in their structure. Comparative sequencing of the three chloroplast genomes showed that the genetic markers atpI, ndhA, ycf1, atpB-rbcL, ndhF-rpl32, petA-psbJ, psbM-psbD, and rps16-psbK effectively distinguish E. senticosus. This investigation, aiming to identify 184 E. senticosus samples from 13 true producing regions, strategically selected atpI and atpB-rbcL genes due to their ease of amplification and length between 700 and 800 base pairs. Genotypes 9 and 10 were determined by analyzing atpI and atpB-rbcL sequences, respectively, according to the results. In addition, the examination of the two barcodes revealed 23 distinct genotypes, which were labeled H1 to H23. The haplotype H10 had a greater proportion and wider reach than any other, positioning H2 in the runner-up position. The haplotype diversity of 0.94 and the nucleotide diversity of approximately 18210 x 10^-3 underscore the significant genetic diversity found in E. senticosus. Analysis of the median-joining network revealed four groups among the 23 genotypes. Biosphere genes pool The star-shaped network, with H2 as its oldest and central haplotype, indicated population expansion of E. senticosus from authentic production regions. This study founds the exploration of genetic quality and chloroplast genetic engineering in E. senticosus, instigating further research into the genetic mechanisms governing its populations and providing fresh viewpoints on the genetic evolutionary trajectory of E. senticosus.

UPLC-Q-TOF-MS and GC-MS, in combination with non-targeted metabonomic analysis and multivariate statistical analysis, were used in this study to determine and compare the five indicative nardosinone components using UPLC. A comprehensive analysis was performed to identify the fundamental chemical components present in Nardostachyos Radix et Rhizoma, examining both imitated wild cultivation and authentic wild specimens. A consistent outcome was observed from the multivariate statistical analysis employing both liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). Groups G8-G19 of the wild group and G1 and G2 of the imitative wild cultivation group fell under category 1; conversely, category 2 consisted of G7 from the wild group and G3-G6 from the imitative wild cultivation group. Twenty-six chemical components were found through LC-MS analysis utilizing both positive and negative ion detection modes. Using UPLC, the concentrations of five indicative components (VIP>15) were determined in both the imitative wild cultivation group and the wild group. The imitative group displayed levels of chlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, linarin, nardosinone, and total content 185, 152, 126, 90, 293, and 256 times higher than the wild group, respectively. Ten differential peaks emerged from the GC-MS data, analyzed using the OPLS-DA technique. The imitative wild cultivation group demonstrated significantly elevated levels (P<0.001 and P<0.05) of -humulene and aristolene, in comparison with the wild group. Conversely, the imitative wild cultivation group presented significantly diminished levels (P<0.001 and P<0.05) of seven components, including 56-epoxy-3-hydroxy-7-megastigmen-9-one, -eudesmol, and juniper camphor, and 12-isopropyl-15,9-trimethyl-48,13-cyclotetrade-catriene-13-diol, when compared to the wild group. Subsequently, the key chemical compounds within the imitated wild group and the natural wild group shared a substantial degree of correspondence. While the non-volatile components in the imitative wild cultivation group were more prevalent than in the wild group, the concentration of some volatile components showed an opposite pattern. RBN-2397 The evaluation of Nardostachyos Radix et Rhizoma's quality, employing scientific data from this study, encompasses both cultivated and wild-harvested varieties.

The cultivation of Polygonatum cyrtonema is plagued by rhizome rot, a prevalent global disease also impacting perennial medicinal crops like Panax notoginseng and P. ginseng. At present, no effective method for control has been developed. Employing three biocontrol microbes—Penicillium oxalicum QZ8, Trichoderma asperellum QZ2, and Brevibacillus amyloliquefaciens WK1—this study validated the pathogenicity of six suspected pathogens to P. cyrtonema, focusing on their impact on rhizome rot. Observations confirmed the presence of Fusarium species. HJ4, a Colletotrichum species. The presence of Phomopsis sp. and HJ4-1 was confirmed. Rhizome rot of P. cyrtonema was identified to be caused by pathogens HJ15, while a novel finding highlighted Phomopsis sp. as a possible culprit in P. cyrtonema rhizome rot. Additionally, the inhibiting influence of biocontrol microbes and their secondary compounds on the growth of three pathogens was ascertained via a confrontation culture technique. The results explicitly show that the three biocontrol microbes were successful in considerably curbing the growth of the three tested pathogens. The secondary metabolites from *T. asperellum* QZ2 and *B. amyloliquefaciens* WK1 showed considerable inhibition of the three pathogens (P<0.005). The effect observed with the sterile filtrate of *B. amyloliquefaciens* WK1 was significantly greater than that achieved with the high-temperature-sterilized filtrate (P<0.005).
