A new compound, 11-O-(3'-O-methylgalloyl)-bergenin (1), along with 11 known compounds (2-12), has been isolated from the rhizome of Astilbe chinensis. The chemical structure of compound 1 was determined by IR, MS, and NMR spectral data. All compounds were evaluated for the cytotoxic activity in vitro, and compound 4 showed a moderate cytotoxic activity against HepG2 cells.

Astilbin exerts anti-hypersensitivity by regulating metabolic demand and neuronal activity in rodent model of neuropathic pain.
Ann Med
December 2024
Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Article Synopsis
- Traditional Chinese medicine, specifically astilbin, is studied for its effectiveness in managing pain, focusing on its active components and methods of action.
- Experiments using neuropathic rat models demonstrated that both systemic and spinal delivery of astilbin significantly reduced both chronic and acute pain behaviors, with specific effective dosing identified.
- The study highlighted that astilbin works by influencing neuronal metabolic processes and modulating excitatory synaptic activity, leading to its pain-relieving effects.

In the current study, we have investigated the secondary metabolites present in ethnomedical plants used for medicinal purposes-Astilbe chinensis (EK1), Scutellaria barbata D. Don (EK2), Uncaria rhynchophylla (EK3), Fallugia paradoxa (EK4), and Curcuma zedoaria (Christm.) Thread (EK5)-and we have compared them with five compounds of synthetic origin for the inhibition of PARP-1, which is linked to abnormal DNA replication, generating carcinogenic cells.

Glycosylation plays a very important role in plant secondary metabolic modifications. Neodiosmin, identified as diosmetin-7--neohesperidoside, not only acts to mitigate bitterness and enhance the flavor of food but also serves as a pivotal metabolite that reinforces plant immunity. Investigating its biosynthetic pathway in plants is crucial for optimizing fruit quality and fortifying plant immune responses.
