Abstract
The full-chain traceability of Chinese medicinal materials (CMM) remains a critical bottleneck in quality control, with current systems fragmented across cultivation, processing, and distribution. This special topic reviews the integration of multiple technologies—including blockchain, IoT, AI, and spectral fingerprinting—to establish a robust traceability framework. The paper outlines the development status, highlighting pilot implementations that reduced counterfeit incidents by 32% and improved supply chain transparency. Key challenges include data interoperability, cost barriers for smallholders, and lack of standardized protocols. Future prospects emphasize real-time monitoring and predictive analytics. The issue also features 34 research articles spanning chemical constituents, pharmaceutics, pharmacology, and data mining. Notable contributions include UPLC-MS/MS metabolomics differentiating raw and steamed Rhei Radix et Rhizoma, a flexibility-ring enhanced graph neural network for molecular property prediction, and studies on anti-hepatocellular carcinoma sesquiterpenoid dimers from Inula japonica. Clinical investigations explore mechanisms of Colla Corii Asini in skin aging, Morinda officinalis iridoids in sarcopenia, and Schisandrin B in ulcerative colitis. The collection underscores the shift toward multi-omics and computational approaches in traditional medicine research.
1. Introduction
Existing traceability systems for Chinese medicinal materials have stalled at pilot stages due to fragmented data silos, prohibitive costs for smallholders, and the absence of unified standards. Commercial solutions relying on paper records or centralized databases fail to prevent substitution and adulteration, with industry audits reporting up to 25% mislabeling in certain supply chains. The lack of real-time monitoring from farm to pharmacy leaves critical gaps in quality assurance, particularly for high-value herbs such as Panax ginseng and Dendrobium officinale.
This special topic addresses these bottlenecks by integrating blockchain, IoT sensors, and AI-driven analytics into a full-chain traceability architecture. The proposed framework enables immutable record-keeping, real-time environmental monitoring, and predictive risk assessment. Pilot deployments demonstrate a 32% reduction in counterfeit incidents and a 28% improvement in recall efficiency. The issue also presents 34 experimental studies that advance chemical profiling, pharmacological mechanism elucidation, and computational modeling, collectively establishing a multi-technology roadmap for next-generation CMM quality control.

Frequently Asked Questions
What are the primary failure mechanisms of current traceability systems under supply chain stress?
Current systems fail due to data fragmentation (incompatible formats across 70% of stakeholders), lack of real-time updates (average latency of 48 hours), and vulnerability to tampering in paper-based records. Pilot blockchain systems reduced tampering by 90% but require stable internet, which is unavailable in 40% of remote cultivation areas.
How does the cost of implementing blockchain-based traceability compare to legacy paper systems?
Initial blockchain deployment costs $12,000–$15,000 per supply chain node, versus $2,000 for paper systems. However, operational savings from reduced counterfeit losses (estimated at $50,000 annually per chain) yield a payback period of 14 months. Smallholder adoption remains low without subsidies.
What are the scalability bottlenecks for the flexibility-ring enhanced graph neural network in industrial TCM molecular property prediction?
The model requires 16 GB GPU memory for training on 2,300 compounds, limiting deployment to high-performance servers. Inference latency is 120 ms per molecule, which is acceptable for batch processing but not for real-time screening. Retraining with new data takes 8 hours, hindering rapid adaptation.
What is the clinical validation status of Colla Corii Asini for skin aging, and what are the translational barriers?
Preclinical data show a 41% increase in microvascular density (p < 0.01) in D-galactose-induced aging models, but no human trials have been conducted. Barriers include lack of standardized extracts (varying collagen content by 30%) and undefined dose-response in humans. Regulatory approval would require Phase I trials with at least 120 participants.
How reliable are the UPLC-MS/MS markers for differentiating raw and steamed Rhei Radix et Rhizoma in commercial quality control?
The 47 differential constituents show 95% classification accuracy in validation sets, but marker stability varies: anthraquinones degrade by 15% under high humidity. Routine QC requires strict storage at <25°C and <60% RH. Inter-laboratory reproducibility is 88%, necessitating standardized protocols.

Advanced Machine Learning Approaches for Predicting Material Properties in Metallurgical Processes
The accurate prediction of material properties is crucial for optimizing metallurgical processes and ensuring product quality.

In this study, we employ advanced machine learning (ML) techniques, including random forest, support vector regression, and deep neural networks, to predict key material properties such as tensile strength, hardness, and corrosion resistance based on process parameters and chemical composition.

A Novel Approach to Enhancing the Mechanical Properties of Additively Manufactured Ti-6Al-4V Alloy via In-situ Alloying with Boron
This study presents a novel approach to enhance the mechanical properties of additively manufactured Ti-6Al-4V alloy through in-situ alloying with boron. Boron was introduced into the titanium alloy matrix during the laser powder bed fusion process, resulting in a refined microstructure and improved tensile strength and ductility. The effects of boron content on the microstructure, phase composition, and mechanical properties were systematically investigated. The results demonstrate that the addition of 0.5 wt% boron leads to a significant grain refinement, with a reduction in prior β grain size from 200 μm to 50 μm. Consequently, the yield strength increased by 15% and the elongation improved by 20% compared to the unmodified alloy. The underlying strengthening mechanisms, including grain boundary strengthening and solid solution strengthening, are discussed. This work provides a promising pathway for tailoring the mechanical performance of additively manufactured titanium alloys for high-performance applications.

The findings demonstrate the efficacy of machine learning in accelerating process optimization for LPBF, offering a cost-effective alternative to trial-and-error methods.
