Widely Targeted Metabolomics Analyses Provide Insights into the Transformation of Active Ingredients During Drying and the Mechanisms of Color Change for Forest Ginseng ( C. A. Mey. cv. Sativi-nemoralis).

In this study, we investigated the mechanism of conversion of active components as well as the color change of forest ginseng (FG) during the drying process with the self-developed negative-pressure circulating airflow-assisted desiccator (PCAD) drying method, using a widely targeted metabolomics analytical method based on ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). During the drying process, a total of 1862 metabolites were identified in FG, along with 748 differential abundant metabolites (DAMs). Further analysis of the types and metabolic pathways of the DAMs revealed that both primary and secondary metabolites changed by 50-70% moisture content (MC); secondary metabolites dominated with a 30-50% MC, and primary metabolites dominated with a 10-30% MC, which revealed the differences in the transformation of the active ingredients in the drying process.

Effect and Mechanism of Specnuezhenide on Chemotherapy-induced Myelosuppression.

Objective: This study aimed to investigate the therapeutic effect of Specnuezhenide on myelosuppression induced by chemotherapy and clarify its mechanism.

Methods: In this study, we measured peripheral blood cells, thymus index, spleen index, bone marrow nucleated cells (BMNCs), and the number of cell colonies counted in vitro by hematopoietic progenitor cells (HPCs) to determine the effect of SPN on cyclophosphamide (CTX)-induced myelosuppression. The alterations in the expression of relevant proteins, the cell cycle, and cytokines associated with hematopoietic cells were examined to better understand how it works.

Effect of Ligustri Lucidi Fructus on myelosuppression in mice induced by cytoxan.

In this study, we aimed to demonstrate the therapeutic effect of Ligustri Lucidi Fructus on chemotherapy-induced myelosuppression and elucidate its mechanism. A pharmacological study was conducted to investigate the mechanism of the inhibiting effects of Ligustri Lucidi Fructus on cyclophosphamide-induced bone marrow suppression in mice. HPLC was used to measure the chemical components.
