Buyer Decision Guide
With baicalin, the assay is only half the specification. The companion flavonoids and the method decide whether two lots behave the same way in a formula.
- Baicalin: 85% by HPLC, released against the batch COA.
- Baicalein and wogonin reported per batch, since both affect colour and taste.
- Identity confirmed as Scutellaria baicalensis root, not a mixed Scutellaria species.
- Method and reference standard recorded so results are reproducible at your laboratory.
- Loss on drying, ash, heavy metals and microbiology reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
The 85% and 90% baicalin products state different assay grades; the 10:1 root extract is specified by extraction ratio. Check the named marker, method, batch result and intended specification before treating them as substitutes.
Compare listed grades: 90% baicalin grade; 10:1 root extract. Confirm the current batch specification before substitution.
Quality and Documentation
Baicalin is assayed by HPLC with baicalein and wogonin integrated on the same run. Moisture, ash, heavy metals and microbiology are reported per lot, with retention samples kept for each batch.
