In the evolving landscape of botanical research and specialty nutraceuticals, plant-derived alkaloids are gaining unprecedented attention for their targeted biological activity. Among them, Tetrandrine stands out as a highly researched bisbenzylisoquinoline alkaloid with potent anti-inflammatory, immunomodulatory, and calcium-channel modulating properties.
At Nanjing Spring & Autumn Biological Engineering Co., Ltd. (CQ Herb), we specialize in the precision extraction and supply of high-purity plant alkaloids. Whether you are developing pharmaceutical intermediates, advanced research reagents, or specialized functional formulations, understanding the science, sourcing, and supply chain of Tetrandrine is essential for product success. This guide explores its profile, applications, and why CQ Herb is your trusted global partner.
Tetrandrine (CAS: 518-34-3, Molecular Formula: C₃₈H₄₂N₂O₆) is a naturally occurring bisbenzylisoquinoline alkaloid primarily isolated from the dried roots of Stephania tetrandra (Han Fang Ji). Recognized for its complex pharmacological profile, it interacts with multiple cellular pathways, including calcium channel modulation, NF-κB signaling inhibition, and autophagy regulation.
CQ Herb supplies Tetrandrine in multiple specifications tailored to your R&D or production needs, with 98%+ HPLC purity as our standard for pharmaceutical and laboratory use. Lower potency extracts (e.g., 50%-80%) are also available for early-stage formulation screening.
Consistency begins at the source. Our Tetrandrine is sustainably harvested from certified Stephania tetrandra rootstocks cultivated in controlled agricultural zones. The extraction process leverages:
This ensures every shipment meets pharmacopeial standards for heavy metals, pesticides, microbiological limits, and alkaloid consistency.
Tetrandrine’s multi-target activity makes it highly valuable across several B2B sectors:
Widely utilized as a reference compound or active intermediate in research targeting fibrosis, autoimmune modulation, and oncology pathways. Its calcium antagonistic properties also support cardiovascular and metabolic research.
Incorporated into joint health, inflammatory response, and cellular wellness formulations. Often paired with synergistic botanicals for targeted metabolic or immune-support products (subject to regional regulatory compliance).
Studied for its potential to modulate skin inflammation, support barrier integrity, and protect against oxidative stress in advanced topical serums and clinical-grade skincare.
High-purity isolates (≥98% HPLC) serve as certified reference materials for pharmacopeias, academic labs, and quality control testing in herbal and pharmaceutical manufacturing.
Sourcing a consistent, compliant alkaloid requires more than just a catalog listing. Here’s why international clients choose CQ Herb:

Q: What is the standard lead time for Tetrandrine orders?
A: Sample orders (10g–100g) ship within 3–5 business days after payment confirmation. Bulk production (1kg+) typically requires 7–12 working days, depending on specification and current inventory.
Q: Do you offer free samples for testing?
A: Yes. We provide complimentary samples (10g–20g) for R&D evaluation. Customers only cover courier shipping fees.
Q: What are your payment terms?
A: For samples and small orders: PayPal, Western Union, or T/T. For bulk shipments: 30% deposit via T/T, with 70% balance before dispatch. Secure payment gateways available for eligible regions.
Q: Can you provide regulatory or pharmacopeial documentation?
A: Absolutely. We supply full COAs, HPLC/GC-MS reports, residual solvent data, and can assist with REACH, DMF, or regional registration dossiers upon NDA signing.
Q: How should Tetrandrine powder be stored?
A: Store in a cool, dry, light-protected environment at 2–8°C in airtight packaging. Under proper conditions, shelf life is typically 24 months from manufacture date.
