ABSTRACT
By studying various ancient texts such as herbal classics and medical literature from different eras, it was found that there were discrepancies in the records about Bambusae Concretio Silicea(Tian Zhu Huang). In order to establish an accurate foundation, this research was based on ancient herbal literature and combined with plant morphology and investigative studies to examine its earliest mentions in ancient texts, nomenclature, medicinal properties, indications, and quality assessment standards. In the early records, Bambusae Concretio Silicea was referred to by several different names, such as "Zhu Huang" "Tian Zhu Huang" "Zhu Gao" "Zhu Tang", and "Zhu Huang". The earliest known formal usage of the name "Tian Zhu Huang" was found in the book Ri Hua-zi's Materia Medica(Ri Hua Zi Ben Cao). Throughout various ancient texts, the earliest recorded information about Bambusae Concretio Silicea also appeared in Ri Hua-zi's Materia Medica, not in Materia Medica of Sichuan(Shu Ben Cao) or other ancient texts. Ri Hua-zi's Materia Medica provided relevant descriptions of its origin, medicinal properties, and indications, albeit with some errors due to limited knowledge. However, this has been a valuable starting point for future research on Bambusae Concretio Silicea and holds pioneering significance in forming a mature system. As the research delved deeper, the medicinal properties of Bambusae Concretio Silicea have been consistent since Ri Hua-zi's Materia Medica, and the understanding has gradually improved through years of clinical verification. During the investigation process, the authors found limited records on the quality evaluation of Bambusae Concretio Silicea in ancient texts. Although the information is scarce, it serves as a foundational basis for establishing corresponding quality grading standards for Bambusae Concretio Silicea in the future.

Objective: To study the chemical differences between natural and synthetic of Bambusae Concretio Silicea by ultra-high performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Methods: The qualitative analysis of chemical composition was made combined online database and secondary fragmentation cleavage rules, and difference analysis was carried out by the Enhance Peak Find function of PeakView software. Then the converted data was imported into SIMCA-P software to establish an OPLS-DA statistical model and differential secondary metabolites were analyzed. Results: The constituents of Bambusae Concretio Silicea mainly included amino acids, organic acids, alkaloids, glycosides, etc. Among them, 11 components were known, while other 43 compounds were identified for the first time. A total of 14 distinct components, including 2,5-dimethyl-1,3-oxazole-4-carboxylic acid and sucrose, and 12 biomarkers, including 4-(heptyloxy)phenyl-4-(hexyloxy)benzoate, and N-lauryldiethanolamine were identified. Conclusion: This study reveals that the chemical differences between the two herbs are obvious, while betaine and sucrose can be used as the distinguishing indicators. And it provides new ideas and data references for the quality control and clarification of medicinal substances.
