Objective To develop a highly effective HPLC method for standardization of silymarin and for characterization of minor components, which has not been reported previously. Methods An HPLC fingerprinting method and 1 H-NMR spectroscopy were employed to provide assurance for a standardized silymarin product (MK-001). Results A total of 18 marker compounds were identified and characterized including ten flavonolignans and eight small molecules including adenine, adenosine, uridine, and 3,5,7-trihydroxychromone which were first isolated and characterized from silymarin. The HPLC fingerprinting method and 1 H-NMR had been established for complete assignments of HPLC peaks with intensity over 1.0%. Conclusion The successfully established HPLC fingerprinting method and 1 H-NMR could be applied for the standardization of commercial silymarin products. MK-001 represents the first standardized silymarin with the highest content of flavonolignans ( > 90%).

＜正＞A systematic ab initio investigation of the reactions of chloromethanol, dichloromethanol and formyl chloride with water was presented in which water molecules （up to 6） were explicitly included in the reaction system. The decomposition reactions of the chlorinated methanols and formyl chloride were found to be significantly catalyzed by water molecules with the decomposition becoming faster as the number of water molecules increases. Predicted rate constants for the

Sepsis, which refers to a systemic inflammatory response syndrome resulting from a microbial infection, represents the leading cause of death in intensive care units. The pathogenesis of sepsis remains poorly understood although it is attributable to dysregulated immune responses orchestrated by innate immune cells that sequentially release early(e.g., tumor necrosis factor(TNF), interleukin-1(IL-1), and interferon-γ(IFN-γ) and late(e.g., high mobility group box 1(HMGB1)) pro-inflammatory mediators. As a ubiquitous nuclear protein, HMGB1 can be passively released from pathologically damaged cells, thereby converging infection and injury on commonly dysregulated inflammatory responses. We review evidence that supports extracellular HMGB1 as a late mediator of inflammatory diseases and discuss the potential of several Chinese herbal components as HMGB1-targeting therapies. We propose that it is important to develop strategies for specifically attenuating injury-elicited inflammatory responses without compromising the infection-mediated innate immunity for the clinical management of sepsis and other inflammatory diseases.
