Description
STANDARDISED BOTANICAL EXTRACT
Bletilla striata (Thunb.) Rchb.f. — 10:1 extract ratio
白芨 is a ratio extract, which means the quotation has to state the input grade and the extraction solvent before the 10:1 extract ratio figure carries any meaning.

- Identity: Bletilla striata (Thunb.) Rchb.f., Rhizome.
- Appearance: off-white to light brown powder.

How This Grade Differs
No grade of this product was listed on the site before this page, so it introduces the product directly. Confirm the grade in the written quotation before the first order.
Quality and Documentation
Released on a batch certificate covering assay or grade, identity, moisture, heavy metals and microbiology.
Frequently Asked Questions
Can you supply a specimen for identity verification?
A retained sample is kept for each lot and the identity is stated as Bletilla striata.
How recent is the representative batch shown?
The batch referenced is issued per lot; your shipment is released on its own certificate rather than the representative one.
Which safety parameters are tested every lot?
Moisture per specification, ash per specification, heavy metals and microbiology against the approved specification.
How should the material be stored after arrival?
Two years when stored properly. Keep the pack sealed; moisture uptake is the main risk for this grade.
Does the percentage refer to one compound or to a group?
It refers to 10:1 extract ratio, calculated by TLC on the basis stated on the COA.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
