- Product Description
Pterostilbene Powder | Verified Trans‑Isomer Synthetic Nutraceutical Raw Material | Hongda Phytochemistry
Buyers sourcing bulk pterostilbene powder frequently face hard‑to‑detect manufacturing‑related risks. Simple total‑purity HPLC results cannot reflect cis‑isomer content generated by light exposure during synthesis or logistics. Residual‑solvent traces, particle‑size‑related powder segregation, and gradual colour‑shift under improper transit‑storage conditions regularly cause formulation headaches. Missing supporting documentation for novel‑food notification further creates hold‑ups for EU‑market projects.
Our pterostilbene bulk powder is among our regularly‑shipped high‑volume raw‑materials, exported to Europe, North‑America and Southeast‑Asia. Produced via controlled synthetic synthesis and multi‑stage recrystallization inside our own workshop. Every finished lot undergoes separate trans / cis‑isomer profiling, residual‑solvent testing and particle‑characterization before batch release. We hold spot‑stock for standard‑grade and deliver audit‑ready document packages tailored for different regional‑manufacturing requirements.
Disclaimer:This product is sold exclusively as bulk industrial‑manufacturing raw‑material. Not for direct retail‑consumer or personal‑end‑use.

Why do many buyers not choose the standard specifications?
1. A revolutionary 80% vs. 20% bioavailability: Most of the resveratrol in the standard form is metabolized and excreted after entering the intestines. Our trans-Pterostilbene has extremely high lipid solubility, and its oral bioavailability is 4 times that of resveratrol.
2. Extreme purity and single-impurity monitoring: We implement internal controls that are more stringent than those in the pharmacopoeia. We focus on monitoring isomer residues during the synthesis process to ensure that the trans-Pterostilbene content is greater than 99.5%.
3. Customized particle size service: To solve static electricity and clumping during tableting or filling, we offer a micronized specification with a D90 < 15μm. This not only improves dissolution speed but also ensures that the active ingredient is evenly distributed in each capsule when mixing hundreds of kilograms of excipients.

Production Process
- Closed‑system synthesis under low‑light environment Whole synthetic reaction runs within light‑shielded closed‑equipment to minimise photo‑isomerisation. Every batch of incoming chemical reagents goes through identity‑&‑impurity screening; reject non‑conforming feed‑stock before reactor feeding.
- Multi‑stage low‑light recrystallization Multiple‑round controlled‑temperature recrystallization operated under dim‑light condition. This step lowers cis‑isomer and synthetic‑by‑product content and locks target melting‑point range.
- Vacuum low‑temperature desolventisation Strict vacuum drying procedure removes process‑solvent residues without introducing extra thermal‑degradation risk to stilbene molecular‑structure.
- Pulverization & sieve classification (optional micronization) Adjust particle‑size distribution according to project‑needs. Micronized‑grade reduces powder‑segregation risk for high‑speed capsule‑filling and multi‑component dry‑premix work. All pulverization steps keep light‑exposure to absolute minimum.
- Multi‑dimension batch‑release testing Beyond total‑content HPLC‑assay, each lot executes trans‑/cis‑isomer profiling, melting‑point verification, residual‑solvent detection, heavy‑metal and full‑microbial‑panel inspection. No batch gets shipping‑approval without full QC‑team sign‑off.
- Immediate light‑proof inert‑sealed packing Pterostilbene crystal is light‑sensitive. Finished powder is packed right‑after QC‑approval using double‑layer light‑blocking aluminium inner bags. Reinforced moisture‑light‑barrier packing can be arranged for tropical‑zone long‑haul sea‑shipment routes.

FAQ
Q: Is your pterostilbene synthetic or plant-derived?
A: For a 99% purity grade, almost all of it globally is synthetic. Because its content in plants (such as sandalwood) is extremely low and involves endangered species, synthetic methods not only protect the environment but also achieve a purity far exceeding that of extraction methods. We can provide Carbon-14 data to prove its complete consistency with the natural molecular structure.
Q: Will pterostilbene react with minerals in my formulation?
A: Pterostilbene itself is extremely chemically stable. However, because it is fat-soluble, if you are making a liquid formulation, we recommend adding an appropriate amount of emulsifier. For dry powder mixtures, we recommend controlling the moisture content below 0.5%. We can provide you with relevant formulation compatibility test data.
Q: Why is your price 10% higher than some quotes on the market?
A: Impure pterostilbene often has a pungent chemical odor and is prone to discoloration in compound experiments. We sell peace of mind with "one-time audit pass," saving you the huge costs of later recalls or redevelopment.
Q: How can you guarantee batch-to-batch consistency?
A: The Certificate of Analysis includes HPLC chromatograms for each batch.
Q: Can I use your Pterostilbene Powder in vegan products?
A: We provide Non-GMO and Organic certifications upon request.
Q: Can you provide formulation guidance?
A: Our PhD-led team shares solubility data and stability studies to optimize your product.
Q: What’s the lead time for bulk orders?
A: 10–15 days with real-time tracking. Expedited shipping available.
