Buyer FAQ · Product directory
Questions buyers ask about this catalogue.
How is the product catalogue organised?
Four core botanical families – Herbal Extracts, Fruit & Vegetable, Tea & Beverage and Mushroom Extracts – each an image-card directory. Standardised botanical actives, purified single compounds such as geniposide, matrine and crocetin, are catalogued separately, and nutritional and functional ingredients are grouped by chemistry rather than by plant part.
What is the difference between a 10:1 ratio extract and a standardised extract?
A ratio grade is declared as a plant-to-extract ratio such as 10:1. A standardised grade is released on a declared assay, for example 95% OPC or 98% polyphenols, with the analytical method stated on the specification. The catalogue keeps the two apart: 10:1 Ratio Extracts and Standardized Extracts are separate browsing routes.
Where do I compare specifications before requesting a COA?
The Compare Specifications route on this page selects grades by assay and analytical method. Individual specification guides cover ginseng, ashwagandha, boswellia, saw palmetto and green tea, plus a cross-category botanical extract comparison.
Does every product page carry a COA?
Product pages state COA evidence status rather than assuming one. Each page carries specification guidance, the evidence status, FAQs and a quotation path, so the documented position for a grade is visible before you ask for documents.
What should I send when asking for a specific grade?
Botanical source, assay, test method, quantity and destination market. With those five the catalogue can be checked and availability confirmed together with the relevant specification, COA status and quotation.
Which ranges go beyond botanical extracts?
The Nutritional & Functional Ingredients range groups by chemistry: amino acids, vitamins and derivatives, probiotics and postbiotics, peptides and proteins, specialty and liposomal actives, and marine ingredients. Seven further ranges are published as specification hubs with comparison tables and buyer FAQs.
Can I browse by plant part?
Yes. The herbal extract quick filters cover root, leaf, seed, bark, flower and whole-herb extracts, plus 10:1 ratio extracts and liquid extracts. A product can appear in more than one group when both descriptions apply.
What if the grade I need is not in the catalogue?
Use the “Need a specific grade?” route on this page. Availability is confirmed against the specification you provide rather than assumed from the catalogue.
