| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Active pharmaceutical ingredient in antiviral drugs for the treatment of certain viral infections | Extracted from Hypericum perforatum or synthesized chemically |
| Cosmetics Industry | Antioxidant used in skincare products to mitigate free radical damage | Extracted from natural plant sources and purified |
| Food Industry | Natural antioxidant used for food preservation | Extracted from Hypericum perforatum and suitably processed |
| Agricultural Industry | Plant growth regulator to promote crop growth | Prepared via plant extraction or microbial fermentation |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies hypericin content by separation on a reversed-phase column and UV detection at 590 nm. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally similar impurities using diode-array detection across multiple wavelengths. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) by gas chromatographic separation and flame ionization detection. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (Pb, Cd, Hg, As) via inductively coupled plasma mass spectrometry with isotopic resolution. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying under controlled temperature and vacuum conditions. |
| Residue on Ignition | Sulfated Ash Test | Quantifies inorganic residue after high-temperature ignition of the sample with sulfuric acid pretreatment. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generated electrochemically in pyridine-methanol medium. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by detecting rotation of plane-polarized light at 20 degrees C using sodium D-line. |
| pH of Solution | Potentiometric pH Measurement | Evaluates acidity/basicity of aqueous suspension using calibrated glass electrode and reference electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation in laser light scattering. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic bacteria, yeasts, molds, and specified pathogens using selective culture media and filtration. |
| Identity Confirmation | FTIR Spectroscopy | Verifies molecular structure by matching characteristic absorption bands in the mid-infrared region to reference spectrum. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
We are familiar with international trade and export regulations, ensuring all products comply with relevant requirements. We also provide complete documentation to support smooth customs clearance and global delivery.
