Shikimic Acid Powder – Premium Natural Star Anise Extract
Shikimic Acid Powder is a high-purity phytochemical derived from ripe star anise fruit (Illicium lanceolatum, Magnoliaceae family), supplied only from China's Guangxi and Yunnan provinces, the world's leading natural shikimic acid producing locations. This biochemical intermediate is fundamental to the production of chiral drugs, aromatic amino acids, and antiviral treatments; it is also an important component of metabolic pathways. From inexpensive feed additives (20%) to ultra-pure pharmaceutical intermediates (98%), our product can fulfill a wide range of formulation needs with its multi-specification flexibility and pharmaceutical-grade purity requirements. It can also be traced from organic cultivation to final crystallization.

Origin & Traceability
Raw Material Source:
Dried, mature star anise fruit from Guangxi and Yunnan—core global natural shikimic acid zones.
Raw Material Grading:
· Pharmaceutical Grade: Harvested in the current year, devoid of mold, insects, pesticides, and heavy metals, resulting in 98% purity.
· Regular Grade: Use second-grade star anise and scraps for cost-effective extracts of 20% and 50%.
· Organic grade: USDA/ECOCERT certified, chemical-free farming, and separate production line to prevent contamination.
Specification Differentiation:
· Direct spray drying post-extraction at 20% yields rich polysaccharides and organic acids, making it appropriate for feed and low-cost herbal powders.
· 50%: D101 macroporous resin purification is suited for ordinary dietary supplements.
· 98%: Multi-stage resin + ethanol recrystallization for pharmaceutical intermediates and high-end nutraceuticals.
Manufacturing Process
Raw Material Pretreatment ：Manual screening (remove mold/insects), hot air drying at 45–55°C (moisture ≤10%), grinding to 10–20 mesh
Hot Water Extraction ：Purified water (1:10–1:12 ratio), countercurrent extraction at 90–95°C (3×: 2h + 1.5h + 1.5h)
Multi-stage Filtration：Bag filter → Plate-frame filter → Precision membrane filtration
Vacuum Concentration：55–65°C under vacuum, solids 15–20% (avoid degradation above 70°C)
- Purification (20%) Direct drying—no resin; high impurities
- Purification (50%) Single-stage D101 resin → 30% ethanol elution → Alcohol removal
- Purification (98%) Multi-stage resin → Hot ethanol dissolution → Low-temp crystallization (2–3 recrystallizations)
Drying ：Spray drying (20%/50%: 150–160°C inlet); Vacuum drying (98%: 40–48°C
Quality Assurance
Testing capabilities include HPLC assays, ICP-MS heavy metal analysis, GC-MS pesticide/solvent residue screening, and microbiological testing.
Certifications include ISO9001, HALAL, NOP, EOS, KOSHER, cGMP, FSSC22000, HACCP, Non-GMO, and Vegan.
Third-Party Support: SGS/BV re-inspection is offered, along with a COA and MSDS for each batch.
Packaging & Delivery
Standard packaging includes 1kg aluminum foil bags and 25kg drums (inside aluminum foil vacuum bag and cardboard barrel).
Custom options include 200-mesh ultrafine Shikimic Acid Powder for oral liquids and drinks, and 60-80 mesh for tablets and capsules.
Shipping: Worldwide logistics with moisture- and light-proof double-layer sealing that avoids clumping during maritime shipping.
FAQ
Q: Is this natural or synthetic shikimic acid?
A: 100% genuine star anise essence. Guangxi/Yunnan sourcing, with organic batches handled in designated workshops.
Q: Which grade for pharmaceuticals?
A: 98% pharmaceutical-grade undergoes multi-stage resin + recrystallization, resulting in the lowest contaminants in drug intermediates.
Q: Hygroscopicity concerns?
A: The 98% grade exhibits little hygroscopicity. Moisture clumping during transportation is prevented by double-layered sealed packing.
Q: Can you provide samples?
A: Yes, free samples available. MOQ: 1kg.
Q: Lead time and customization?
A: Standard orders typically ship within 7-10 days. Supports OEM/ODM for tablets, capsules, and custom mesh sizes.
