HPTLC Fingerprinting: Ensuring Botanical Identity and Preventing Adulteration

Technical overview of High-Performance Thin-Layer Chromatography (HPTLC) fingerprinting methods used to authenticate plant species and botanical supply chains.

By Sarah Jenkins, QC/QA Laboratory Director
As the global demand for botanical raw materials grows, the supply chain faces challenges with species adulteration, dilution, and substitution. Vague raw material tags or macroscopic inspection are no longer sufficient to guarantee purity. To secure our supply chain, All Authentic Herbs mandates HighPerformance ThinLayer Chromatography (HPTLC) fingerprinting as our primary gatekeeper for raw material intake. What is HPTLC Fingerprinting?...

ICP-MS Analysis: Heavy Metal Contaminant Controls in Botanical Supply Chains

Understanding parts-per-billion heavy metal screening via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for clean label compliance.

By David Vance, Lead Toxicology Analyst
Botanical crops absorb minerals and nutrients directly from the soil. Unfortunately, they can also accumulate toxic heavy metals present in the environment from industrial runoff, legacy pesticide usage, or naturally occurring geologic deposits. Consuming elevated levels of lead, cadmium, arsenic, or mercury poses severe health risks. To protect consumer safety and maintain compliance with strict international regulations (including California Proposition 65 and USP standards), we analyze all bulk ingredients using Inductively Coupled Plasma Mass Spectrometry (ICPMS). The Science of ICPMS...
