Description
COA-BACKED BOTANICAL INGREDIENT
Cistanche deserticola Alcohol-soluble Extract
Alcohol-soluble Cistanche extract is supplied as a dried 10:1 preparation of Cistanche deserticola stem, standardised to the alcohol-soluble fraction. Defining the fraction by solvent gives a material with a different colour, taste and solubility from a water-only preparation, so the specification should be read against the intended carrier. It is a botanical raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
For this grade, agree the extraction solvent, the ratio basis and the behaviour in the buyer’s carrier. Confirm the ratio and its analytical basis on the certificate of analysis before approving a shipment, and request a sample where the carrier system is sensitive to colour or taste.
- Ratio basis and analytical method stated on the certificate of analysis
- Solvent fraction confirmed: alcohol-soluble, not water-soluble
- Colour, taste and solubility agreed against the buyer’s carrier
- Particle size and packing agreed at quotation
- COA, specification sheet and safety data sheet accompany each shipment
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market
How This Grade Differs
Cistanche is offered as water extracts, alcohol-soluble preparations and standardised marker extracts. They carry different fractions and different solubility, and should not be substituted for one another without confirming the specification of the replacement.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
