What “GMP-Grade” Really Means at AIHerba®
If you have been sourcing herbal extracts long enough, this situation may feel familiar. The first batch looks excellent. The COA meets specifications. Your product launches smoothly. Then a later batch arrives with subtle differences—color, odor, flowability, or assay behavior. Nothing technically “fails,” yet your formulation no longer behaves exactly the same.
At that point, many buyers reach the same conclusion:
GMP-grade quality is not just about passing a test. It is about repeatability.
This page explains how AIHerba® defines and delivers GMP herbal extract quality and batch-to-batch consistency—not in theory, but through real manufacturing systems, quality controls, and documentation practices used in our production facility.
Who We Are
AIHerba® | China Natural Plant Extracts Supplier & OEM Factory
Legal entity: Shaanxi Zhonghong Investment Technology Co., Ltd.
AIHerba® is the international brand of Shaanxi Zhonghong Investment Technology Co., Ltd., a China-based manufacturer specializing in natural plant extracts, standardized botanical ingredients, and OEM/ODM solutions for dietary supplements and functional products.
Our customers include supplement brands, formulation teams, distributors, and procurement professionals who require reliable quality, regulatory-aligned documentation, and long-term supply stability—not just competitive pricing.
Why Quality Consistency Is a Manufacturing Issue, Not a Marketing Claim
Botanical extracts are fundamentally different from synthetic chemicals. Their composition is influenced by:
- plant species and subspecies
- harvest season and maturity
- geographic origin and growing conditions
- drying and storage methods
- extraction temperature, solvent type, and duration
- natural variation in active compounds
For this reason, consistency cannot be achieved by testing alone. It must be designed into the manufacturing system.
At AIHerba®, GMP is not treated as a certificate or label. It is the framework that allows us to manage natural variability and deliver extracts that are repeatable, traceable, and suitable for commercial-scale formulations.
What “Quality Consistency” Means at AIHerba®
We define quality consistency across four integrated dimensions:
1) Identity
- Correct botanical species and Latin binomial
- Correct plant part
- Verified authenticity of raw materials
2) Chemistry
- Defined marker compound ranges
- Stable chromatographic fingerprint profiles
- Controlled carrier composition
3) Safety
- Controlled contaminants (microbial limits, heavy metals, residues)
- Documented testing and traceability
4) Performance
- Predictable behavior in real formulations
- Stable flowability, solubility, and processing characteristics
GMP systems connect all four layers into a repeatable process.
Raw Material Control: Where Consistency Begins
Consistency cannot be corrected downstream if it is lost at the raw material stage.
At AIHerba®, raw material control includes:
- verified botanical identity (species and plant part)
- qualified and documented raw material suppliers
- defined harvest and acceptance criteria
- incoming inspection and batch documentation
- lot-level traceability from raw herb to finished extract
We do not rely on open-market sourcing driven purely by price. Stable supply starts with controlled sourcing and qualification.
Standardization: Beyond Single Marker Numbers
Many herbal extracts are sold as “standardized to X%.” While marker standardization is necessary, it does not fully define consistency.
At AIHerba®, we combine:
Quantitative Control
- Marker assays using validated analytical methods (e.g., HPLC/UPLC)
- Defined specification ranges rather than fixed numbers
Qualitative Control
- Chromatographic fingerprint comparison
- Batch-to-batch profile matching to detect compositional drift
A marker assay confirms a number.
A fingerprint confirms chemical identity and balance.
Both are required for reliable commercial supply.
GMP Process Controls Inside Our Manufacturing Facility
As a manufacturer, AIHerba® controls key processing variables through documented GMP procedures, including:
- solvent selection and concentration
- extraction temperature and time
- solid-to-liquid ratios
- filtration and concentration steps
- drying methods (e.g., spray drying or vacuum drying)
- carrier selection and percentage
- milling, blending, and particle size control
All critical steps are recorded in batch manufacturing records, ensuring traceability, reproducibility, and accountability.
Testing, Validation, and Quality Documentation
Every production batch undergoes quality testing aligned with dietary supplement and functional ingredient standards.
Typical controls include:
Identity & Chemistry
- marker compound assay
- fingerprint profile analysis
- moisture or loss on drying
- ash content where applicable
Safety
- microbial limits
- heavy metals
- residual solvents (when relevant)
- additional tests based on raw material risk
Beyond the Certificate of Analysis, we support customers with a complete documentation package, including:
- specification sheets
- SDS and TDS
- allergen and carrier disclosures
- non-GMO statements (when applicable)
- traceability and batch records
This documentation supports regulatory review, audits, and internal quality assessments.
How Buyers Can Evaluate Real Consistency
We encourage customers to assess suppliers based on systems, not promises.
Practical evaluation steps include:
- reviewing multiple recent COAs for stability and method consistency
- confirming retained sample policies
- understanding change control procedures
- conducting pilot trials in real formulations
True consistency is proven over time, across batches, and in real-world use.
