Different starting materials
In the published profile, PINHONBIO® TECA combines asiaticoside with asiatic acid and madecassic acid. Madecassoside is a named constituent with its own selected assay grade. Those descriptions represent different material identities and should remain distinct in a comparison.
What a comparison can establish
A side-by-side record helps explain what each material is and what its assay controls. It cannot establish a relative efficacy ranking without an appropriate study.
| Question | TECA profile | Madecassoside grade |
|---|---|---|
| What is the material? | A specified multi-constituent profile | A named constituent |
| What must the assay identify? | Included constituents and fraction definitions | The named constituent and selected grade |
| What should be aligned? | Method, result basis and batch evidence | Method, result basis and batch evidence |
| What remains a formula question? | Incorporation, stability and performance | Incorporation, stability and performance |
Keep similar names separate
Madecassoside and madecassic acid refer to different substances. A composition declaration naming one should not be read as declaring the other. When a material is changed, review the full identity and analytical dossier rather than matching only the plant source.
Avoid a percentage-only substitution
Do not assume that a headline extract percentage gives an equivalent dose of a particular constituent. Establish the concentration of the constituent that matters to the study using a compatible analytical basis, then assess the complete formula.
Write a traceable selection note
A selection note should identify the proposed function, chosen material, accepted specification, incorporation approach and evidence for the finished formula. The result is a decision that another formulator can understand and reproduce, rather than a general statement that one Centella ingredient is better.
