Total Active Content — UV-Vis Method (Third-Party Lab, On-Demand)

An affordable way to verify the active strength of your botanical. This on-demand service measures the total content of a compound class — such as total phenolics, total flavonoids, or total alkaloids — in your selected botanical product, whether whole herb, powder, extract, or other botanical material, using UV-Vis spectrophotometry.

Testing is carried out by an independent, NABL-accredited (ISO/IEC 17025) third-party laboratory. UV-Vis is a well-established, cost-effective method for quantifying the overall level of an active compound group, making it a practical choice for routine screening, batch-to-batch comparison, and sourcing decisions where a total-class figure is sufficient.

How this compares to HPLC: This test reports the total content of a compound class (e.g. total flavonoids), not the concentration of a single named marker compound. If you need a specific individual compound quantified — for example curcumin, or a named withanolide — choose our Active Compound % (HPLC Method) service instead. UV-Vis is the lower-cost option for a group total; HPLC is the definitive option for a specific marker.

What you receive:

• The measured total active content for the specified compound class, reported as % w/w (or equivalent, e.g. mg GAE/g for total phenolics)
• The analytical method and the compound class measured
• A report tied to the specific batch/lot your product is drawn from

How it works:

1. Add this service to your order alongside your chosen botanical product.
2. We arrange sampling and submit the batch to our partner accredited laboratory.
3. You receive the analytical report by email once testing is complete.

Turnaround: 12-14 days from order confirmation. This is a made-to-order analytical service, so a short lead time applies.

Please note: Results pertain to the specific batch/lot tested and report the total content of the specified compound class by the stated method — not the concentration of an individual marker compound. Figures are analytical measurements; this service reports quantitative results and does not constitute a health, therapeutic, or efficacy claim. For which compound class is measured for a given botanical, see the product page or contact us before ordering.
