alkaloid-profiling
Alkaloid-profiling is an analytical approach that identifies and quantifies the diverse nitrogen-containing alkaloid compounds present within a plant's tissues, often using techniques like mass spectrometry and chromatography. This matters for plant science because alkaloids play key roles in defense against herbivores and pathogens, and mapping their variation helps researchers understand plant biosynthetic pathways, chemical ecology, and potential pharmacological applications.

Researchers mapped 74 distinct alkaloid compounds in a Tibetan medicinal plant called Corydalis impatiens, including 8 never described before. These compounds are likely responsible for the plant's traditional use in treating liver disease.
74 isoquinoline alkaloids were identified across 6 structural classes, including 20 tetrahydroprotoberberines and 19 protoberberines
8 compounds were tentatively identified as new-to-science alkaloids, all belonging to phthalide isoquinoline or benzylisoquinoline subtypes
Feature-based molecular networking (FBMN) proved effective for rapidly cataloging complex alkaloid mixtures and flagging novel compounds in crude plant extracts
