Reference Drug of Huai Xiaomai

Updated: 2026-07-21

Overview

Huai Wheat Reference Drug is a pharmacopoeial-grade material derived from Triticum aestivum L., primarily cultivated in China's Huai River region. It is standardized to ensure consistent biochemical profiles for use in traditional Chinese medicine (TCM) research and manufacturing. Recognized by Chinese regulatory bodies, it serves as a critical benchmark for authentication and quality control of herbal products. Unlike commercial wheat, this reference material undergoes rigorous testing for active compounds like flavonoids, amino acids, and polysaccharides. Its production follows Good Agricultural and Collection Practices (GACP) to minimize contaminants. Laboratories and TCM manufacturers rely on it to validate analytical methods and calibrate equipment.

Physical and Chemical Properties

The material typically presents as intact or milled pale-yellow grains with a mild, characteristic cereal aroma. Key markers include starch content (≥60%) and protein levels (8-12%). Chromatographic profiles highlight bioactive compounds such as tricin and luteolin glycosides, which are quantified for standardization. Solubility varies by component: polysaccharides extract best in hot water, while flavonoids require ethanol-water mixtures. Stability studies indicate a 2-year shelf life when stored below 25°C at ≤65% humidity. Accelerated degradation occurs under UV exposure or high moisture, necessitating opaque, airtight packaging.

Main Applications

In TCM, Huai Wheat Reference Drug underpins quality assurance for anxiolytic and nourishing formulations, particularly those targeting 'heart-spleen deficiency' patterns. Pharmacological studies use it to isolate active fractions for neuroprotective or anti-inflammatory effects. Industrially, it's employed in HPLC and LC-MS method development to quantify markers in commercial products. Some nutraceutical manufacturers incorporate it into standardized extracts for sleep-aid supplements, leveraging its GABA-enhancing properties observed in preclinical models.

Safety and Storage

As a non-toxic botanical reference, it requires no special hazardous material handling. Standard laboratory PPE (gloves, masks) suffices to prevent particulate inhalation during milling. Allergen warnings apply for wheat-sensitive individuals. Optimal storage involves amber glass containers or foil-sealed bags with desiccants. Batch-specific certificates of analysis should document pesticide residues (≤0.1 ppm) and heavy metals (e.g., lead <5 ppm) per ChP 2020 standards. Discard if mold growth or off-odors develop.

B2B Procurement Guide

Reputable suppliers include GMP-certified TCM extract companies like Shanghai Ronghe and veteran herbal distributors. Minimum order quantities often start at 1 kg for reference materials. Request third-party testing reports verifying compliance with Chinese Pharmacopoeia (ChP) monograph requirements. Pricing tiers depend on testing depth: basic batches (identity/purity only) cost ~$50/kg, while fully characterized lots with stability data may exceed $150/kg. For international buyers, confirm export documentation includes CITES exemption certificates, though wheat is rarely restricted.
