Pomegranate Peel Extract Powder HPLC Test Data

Pomegranate peel extract is derived from the pericarp of the pomegranate (Punica granatum L.)-a processing by-product constituting approximately 50% of the fruit's total weight. Through scientific research and industrial validation, it has emerged as a high-value botanical raw material rich in diverse bioactive metabolites. Pomegranate peel contains abundant polyphenols, tannins, and flavonoids, with ellagitannin compounds such as punicalagin, ellagic acid, and gallic acid representing its key active constituents.

Many pomegranate peel extract products on the market merely declare total polyphenol content, lacking precise qualitative and quantitative control over key individual components. This results in significant batch-to-batch quality variation and ambiguous efficacy claims, posing substantial challenges for B2B clients regarding formulation consistency, efficacy validation, and international compliance.

To address this, we introduce this pomegranate peel extract powder rigorously tested via HPLC. It is not merely a raw material, but a comprehensive standardised solution for polyphenolic active ingredients, designed for procurement managers, product development engineers, and quality decision-makers within the plant extract industry.

Physical and Chemical Properties

Safety and Compliance Criteria

This product's safety standards comprehensively reference regulatory requirements from major markets, including China, the European Union, and the United States. Both internal and third-party laboratories have validated all data.

HPLC Fingerprint Characteristics: Based on the established HPLC fingerprinting method, pomegranate peel extract exhibits 15 characteristic fingerprint peaks, used to evaluate the overall chemical profile of the sample. Fingerprint similarity between different batches consistently exceeds 0.968, indicating excellent batch-to-batch consistency in chemical composition. Simultaneous Quantitative Analysis of 8 Monomers: The HPLC method enables simultaneous quantitative determination of the following 8 monomeric phenolic compounds:

• Gallic acid
• Punicalagin (including α/β isomers)
• Catechin
• Chlorogenic acid
• Caffeic acid
• Epicatechin
• Rutin
• Ellagic acid

Recent research data: A recent study conducted HPLC analysis on 10 batches of pomegranate peel extract, identifying 28 common peaks. Punicalagin content ranged from 28.80 to 288.90 mg/g, while ellagic acid content ranged from 6.12 to 17.73 mg/g. These findings indicate that extracts from different sources or processing methods may exhibit significant variations in monomer content. Consequently, HPLC-based monomer quantification serves as a critical method for ensuring consistent raw material quality.

Standard Specifications: This product offers multiple specification options, including total polyphenols UV at 40%, 50%, and 70%, with customisable HPLC monomer content specifications available upon request.

We undertake that an internationally compliant COA accompanies every batch of product. The development and validation of testing methods for this product integrate authoritative standards such as the United States Pharmacopoeia, European Pharmacopoeia, and Chinese Pharmacopoeia to ensure global data compliance. Furthermore, every test result on the COA is traceable to original records and supports audit verification by customers or third parties.

Important Note: The COA information and fingerprint spectra provided on this page are for illustrative purposes only, demonstrating our quality control dimensions and capabilities. The specific COA documentation for actual products (including precise batch numbers, HPLC fingerprint spectra, and monomer quantification data) shall be subject to the final release by our business specialists.

We employ our proprietary green preparation process to efficiently extract and purify highly active polyphenolic compounds from pomegranate peel, a by-product of pomegranate processing. The diagram below illustrates the key process flow from raw material to finished product.

Further Information: The flowchart above outlines the primary stages of our process. For detailed production information regarding specific process parameters, production capacity, customised manufacturing, and other technical aspects, please get in touch with our business specialists(cwj@appchem.cn). We will provide further technical consultation tailored to your specific requirements.

Our quality management system constitutes a closed-loop ecosystem spanning the entire lifecycle from cultivation and production through testing to release. Its core principles are "prevention-oriented, end-to-end controllability, and data traceability".

Source Control (Upstream)

• Geographical Advantage: Pomegranates are extensively cultivated across China, with regions such as Lintong in Shaanxi serving as primary production areas for premium fruit, yielding substantial annual harvests.
• By-product Utilisation: The process primarily employs pomace by-products from pomegranate juice processing as initial raw materials, aligning with circular economy and sustainable development principles.
• Dual Verification for Raw Material Entry: Each batch of raw materials must be accompanied by a certificate of origin. Upon arrival, materials undergo rapid QC screening (moisture content, TLC screening). Only compliant batches enter the holding area for comprehensive testing, including pesticide residue, heavy metals, and HPLC fingerprint profiling, ensuring only premium raw materials enter production.

Production Process Control (Midstream)

• HACCP-Based Critical Point Management: Multiple Critical Control Points are established throughout the production line. For instance, online monitoring is conducted during extraction (CCP1), resin purification (CCP2), and drying (CCP3) to ensure processes operate within pre-validated "design space".
• Batch Clarity Management: Rigorous implementation of area clearance, material identification, and electronic batch record systems eliminates any potential for confusion or cross-contamination.

Laboratory Quality Assurance (Downstream)

• Release Testing and Stability Studies: Each batch of finished product must undergo comprehensive testing covering all physicochemical and safety parameters. Utilising advanced analytical instruments, including HPLC, UV, and GC, we assess multiple quality indicators such as fingerprint profile similarity, polyphenolic monomer content, loss on drying, heavy metals, and microbial counts.
• Stability Testing: Conduct long-term and accelerated stability studies in accordance with internal quality control guidelines to scientifically determine shelf life.

Digital Traceability and Continuous Improvement

• End-to-End Electronic Traceability System: Through the MES system, we achieve bidirectional electronic traceability from customer orders to sales dispatch.
• Third-Party Authoritative Validation: Finished products are periodically submitted to international third-party institutions such as SGS and Eurofins for parallel testing, serving as independent validation of our internal quality control system.

Our transparent commitment to quality and R&D capabilities is underpinned by the following authoritative certifications, patented technologies and supporting documentation.

Obtaining Originals and In-Depth Audits: We fully recognise the importance of reviewing original documentation during the supplier selection process. Should you require the originals or certified copies of the aforementioned certificates, patent documentation, or batch-specific supporting files for formal supplier evaluation or reference purposes, please contact us. We shall make every effort to provide the requested materials, thereby supporting your decision-making process.
