Cultivar to chemotype: characterizing complex botanicals with mass spectrometry metabolomics.

Medicinal Plants
That echinacea or ashwagandha supplement on your shelf may not contain what the label claims — this research is building the chemical toolkit that lets regulators and consumers verify exactly what's in a botanical product before it's swallowed.
When you buy an herbal supplement, you're trusting that the plant inside is what the label says — but mislabeling and substitution are surprisingly common. Researchers are using a technique that reads the thousands of chemical compounds in a plant like a unique fingerprint, making it possible to tell species apart, catch fakes, and understand why the same herb grown in different places might have different effects. This is slowly turning botanical identification from guesswork into something closer to a precise science.
Key Findings
Untargeted mass spectrometry metabolomics can profile thousands of compounds simultaneously in complex plant mixtures, enabling taxonomic classification at the cultivar and chemotype level.
The method can detect adulteration and misidentification in botanical dietary supplements and herbal medicines — a persistent problem in a largely self-regulated industry.
Metabolomics datasets reveal how chemical variation between plant materials relates to differences in nutritional, medicinal, or toxicological effects, linking chemistry to real-world safety and efficacy.
chevron_right Technical Summary
Scientists are using a powerful chemical fingerprinting technique called mass spectrometry metabolomics to identify, verify, and characterize herbal supplements and medicinal plants more accurately than ever before. This approach can detect when products are mislabeled or adulterated and reveal how plant chemistry varies by cultivar, growing conditions, and processing.

Ethnobotany is the interdisciplinary study of how humans use, manage, and perceive plants across different cultures, drawing on knowledge from botany, anthropology, ecology, and chemistry. It matters for plant science because it documents traditional ecological knowledge that can reveal previously
