() tuber is a valuable herbal medicine used to treat many diseases. The procedure of establishing a reasonable and feasible quality assessment method for tuber is important to ensure its clinical safety and efficacy. In this research, an effective and comprehensive evaluation method for assessing the quality of has been developed, based on the analysis of high performance liquid chromatography (HPLC) fingerprint, combined with the quantitative analysis of multi-components by single marker (QAMS) method. The contents of the seven components, including gastrodin, -hydroxybenzyl alcohol, -hydroxy benzaldehyde, parishin A, parishin B, parishin C, and parishin E were determined, simultaneously, using gastrodin as the reference standard. The results demonstrated that there was no significant difference between the QAMS method and the traditional external standard method (ESM) ( > 0.05, RSD < 4.79%), suggesting that QAMS was a reliable and convenient method for the content determination of multiple components, especially when there is a shortage of reference substances. In conclusion, this strategy could be beneficial for simplifying the processes in the quality control of tuber and giving references to promote the quality standards of herbal medicines.

Background: Gastrodiae rhizoma (GR) refers to the dried tuber of Bl. and has been used for many centuries to treat brain diseases, such as Alzheimer's disease, major depressive disorder, and cerebral ischemia. However, the processing of GR is complex and varied, resulting in unstable clinical treatment effects.

Parishin, a natural compound, has demonstrated significant potential in mitigating age-related phenotypes and improving outcomes in age-associated diseases. Given that aging is a major risk factor for numerous chronic conditions, including pulmonary fibrosis, we investigated parishin's effects on cellular senescence and lung health. In our study, we treated mouse lung epithelial cells with parishin and observed a reduction in cellular senescence markers alongside an upregulation of sirtuin 1 (SIRT1).

Ethnopharmacological Relevance: Ischemic stroke (IS) a complex pathological event emerging as one of the most serious threats with huge economic impact in the 21st century. Following IS, multiple cascades and pathways are stimulated, culminating in long term consequences. One of Chinese Traditional Medicine, Tianma Siwu Decoction (TSD), is known to have sedative-hypnotic, anticonvulsant and anti-inflammatory effects, which is usually used to treat migraine and ischemic stroke, but its potential pharmacological mechanism remains unclear.

Ethnopharmacological Relevance: Quality control is a critical element for Traditional Chinese medicine (TCM). Due to the varied chemical components, mechanisms of action, and pharmacological functions in TCM, ensuring quality is more challenging compared to chemical drugs. Then, the concept of quality markers (Q-markers) was proposed and ideal Q-markers for TCM prescriptions need to compliant with "five principles", including pharmacological effectiveness, specificity, transfer and traceability, measurability, and prescription compatibility.
