LeafWorks® Botanical Microscopy & Morphological Identification
In today’s global herbal ingredient and dietary supplement market, accurate plant identification requires more than a single analytical method. Morphological and microscopic analysis remains a foundational and FDA-recognized approach for verifying botanical identity, assessing quality of the material, and confirming correct plant part.
Led by renowned microscopist, Kirsten Tripplett, LeafWorks offers expert macroscopic and high-magnification microscopic botanical identification services as a complement to our genomic platform or as a rigorous stand-alone method.
Using authenticated herbarium reference materials and pharmacopoeial monographs, our microscopy services evaluate qualitative plant characteristics — including tissue architecture, vascular elements, crystal structures, surface hairs, and organ-specific morphology — to determine identity, detect plant part, and assess overall material quality. Features such as plant part or non-biological contaminants are not detectable by DNA alone and can be especially valuable for confirming identity requirements for 21 CFR 111 as well as FDA guidelines.
Our botanical microscopy services are led by Kirsten Tripplett, Ph.D., whose decades of anatomical expertise and extensive dietary supplement industry experience bring rare taxonomic depth to modern ingredient verification. Her use of authenticated comparative collections and validated morphological techniques has been commended during FDA audit as a well-substantiated and recommended approach for botanical identification.
LeafWorks offers:
- High-magnification microscopic analysis of powdered botanical ingredients
- Low-magnification macroscopic evaluation of whole or chopped plant materials
- Identification of plant part(s) and taxon where possible
- Detection of adulterants, contaminants, and filth
- Digital image documentation of key diagnostic features
- Certificate of Analysis suitable for production records and cGMP substantiation
Microscopy can be applied to raw plant materials, powders, some fungal fruiting body powders, composite lot samples, and evaluation materials for supplier qualification.
We advocate for an orthogonal testing strategy — combining genomic analysis with morphological and microscopic verification — to deliver well-substantiated, defensible identity results that meet 21 CFR 111 and FDA expectations for appropriate botanical identification methods.
Know. Certify. Verify.
From genome to morphology — complete botanical clarity.
