Product Description
Baicalin powder, a flavonoid compound, is extracted and isolated from the dried roots of Scutellaria baicalensis Georgi, a plant in the Lamiaceae family. It is one of the main active components of Scutellaria baicalensis. At room temperature, it appears as a pale yellow powder with a bitter taste.
Scutellaria baicalensis Georgi, commonly known as Huang Qin, is a traditional Chinese medicinal herb with a long history of therapeutic use. Its primary bioactive component, baicalin, is a flavonoid compound exhibiting a wide range of biological activities. In traditional Chinese medicine, Modern research has demonstrated that baicalin possesses anti-inflammatory, antioxidant, antibacterial, antiviral, anti-allergic, photoprotective, and skin-whitening effects, leading to its broad applications in the pharmaceutical and cosmetic fields. Baicalin present in Scutellaria baicalensis extract can effectively scavenge free radicals, inhibit melanin production, and enhance skin's antioxidant capacity. Furthermore, it exhibits significant ultraviolet (UV) absorption capabilities, positioning it as a potential natural sunscreen agent. Additionally, baicalin can modulate immune function and alleviate inflammatory responses, suggesting its beneficial effects on skin conditions such as atopic dermatitis.
At Jiuyuan Biotech, our Baicalin Powder is extracted from cultivated Scutellaria baicalensis roots grown in the Qinling Mountain region of Shaanxi Province - an area whose soil mineral profile and altitude produce roots with naturally elevated baicalin content. Every batch is standardized by HPLC and shipped with a full COA covering assay, heavy metals, pesticide residues, solvents, and microbiology.

Active Compounds

On Baicalin vs. Baicalein: A common point of confusion for new buyers. Baicalin is the glycoside form - more stable, higher yield from extraction, and the standard commercial form. Baicalein is its aglycone (de-glycosylated) metabolite, produced in the gut by microbial action or in vitro by enzymatic hydrolysis. Some formulators prefer baicalein for applications targeting enhanced bioavailability, though baicalin remains the dominant commercial specification.
Manufacturing Process
Our extraction process is neither outsourced nor abbreviated. Here's how baicalin moves from root to drum at our Shaanxi facility:
1. Raw Material Selection & Incoming QC Roots are sourced from contracted farms within a 200 km radius of our plant. Each incoming lot is tested for identity (TLC/HPLC), moisture, and pesticide residues before entering production.
2. Pre-Treatment & Comminution Dried roots are cleaned, sorted, and milled to a defined particle size to maximize extraction surface area and minimize solvent consumption.
3. Solvent Extraction We use food-grade ethanol as the primary extractant. Extraction parameters - temperature, solvent-to-material ratio, and contact time - are validated and locked per product specification. No chlorinated solvents are used.
4. Filtration & Concentration The crude extract is filtered through multi-stage systems and concentrated under reduced pressure (vacuum evaporation) to preserve thermolabile constituents.
5. Purification & Crystallization For high-purity grades (≥95%), the concentrated extract undergoes column chromatography or recrystallization to remove co-extracted impurities and achieve target assay values.
6. Spray Drying / Vacuum Drying The purified extract is dried using controlled spray-drying or vacuum-drying depending on the target grade, yielding a consistent, free-flowing powder.
7. Milling, Sieving & Blending Final powder is milled to specification, sieved to 80 mesh (or custom), and blended for batch homogeneity.
8. In-Process & Final QC Every batch undergoes in-house HPLC assay, microbiological testing, and heavy metal screening before release. Third-party verification is available on request.

Comparison: Baicalin Grades & What They Mean for Your Formula
One of the most persistent pain points among supplement buyers is grade confusion - paying for 85% and receiving something that performs like 60%, or overpaying for 98% when 85% fully meets the application requirement. Here's a transparent breakdown:
|
Grade |
Purity (HPLC) |
Typical Application |

Supplements, functional food |
✦ |
Most cost-effective; meets most label claims |

The honest answer on 98%: Unless your application genuinely requires pharmaceutical reference-grade material, 85%–90% HPLC baicalin delivers equivalent functional performance in supplement and cosmetic applications at a significantly lower cost per kilogram. We will tell you this upfront - because the right specification for your product is the one that serves your formulation, not our margin.

FAQ
Q1: What is the difference between baicalin and baicalein? Baicalin (CAS 21967-41-9) is a flavonoid glycoside - it has a glucuronide sugar group attached to the baicalein aglycone. In the body, intestinal microbiota hydrolyze baicalin into baicalein, which is then absorbed. Commercially, baicalin is the standard extract form due to higher yield and stability. Baicalein (CAS 491-67-8) is available as a separate product for applications requiring the aglycone form directly.
Q2: Is your baicalin powder water-soluble? Standard baicalin has limited aqueous solubility (approximately 0.2 mg/mL in neutral water). For water-dispersible applications - beverages, effervescent tablets, or liquid formulations - we offer a cyclodextrin-complexed or spray-dried dispersion form with significantly improved dispersibility. Inquire for technical details and pricing.
Q3: Does your product comply with EU regulations for botanical extracts? Yes. Our baicalin powder is produced in compliance with EU Regulation 396/2005 on pesticide maximum residue levels and is accompanied by documentation supporting EU market entry. Buyers targeting the EU market should note that Scutellaria baicalensis extract is on the EU Botanical Compendium; we recommend consulting your regulatory counsel for the specific product category.
Q4: How do you ensure batch-to-batch consistency? Consistency starts at the raw material stage - we source from contracted farms with defined cultivation protocols. In-process HPLC monitoring at extraction and post-drying stages ensures the assay stays within specification. Each batch is assigned a unique lot number with full traceability back to the source field.
Q5: Can I get a sample before placing a bulk order? Absolutely. We offer analytical samples (100 g) and formulation samples (up to 1 kg) for qualified buyers. Samples ship with a full COA. Contact our sales team with your company details and intended application to initiate the sample request.
Q6: What certifications are relevant for selling baicalin-containing products in the U.S. market? For dietary supplement applications, the key compliance framework is 21 CFR Part 111 (cGMP for dietary supplements). Our facility is FDA-registered and cGMP-compliant. We provide the documentation - COA, MSDS, allergen declaration, country of origin - that your QA team needs for supplier qualification under 21 CFR 111.75.
Q7: Is baicalin considered safe for long-term use in supplements? Baicalin has a long history of use in Traditional Chinese Medicine as part of Huang Qin (Scutellaria root). Contemporary safety data, including published toxicological studies, support its use in supplement applications at established dosage ranges. That said, formulation-level safety assessments remain the responsibility of the finished product manufacturer, and we recommend reviewing the relevant literature and consulting a qualified toxicologist for your specific application.
Q8: Do you offer private label or white-label services? Our core business is bulk ingredient supply. We do not offer finished product manufacturing or private label capsules/tablets. We focus on being the best possible upstream partner - so that your downstream product is built on a reliable, verified foundation.
