Analysing three commercially grown South African strains, researchers identified 79 phenolic compounds, including 25 never previously reported in Cannabis and 16 tentatively classified as flavoalkaloids.
The rare compounds were concentrated mainly in the leaves of one strain, revealing sharp chemical variation and suggesting discarded plant material may hold biomedical value beyond cannabinoids.
Using two-dimensional liquid chromatography and high-resolution mass spectrometry, the team said the findings, published in Journal of Chromatography A, show cannabis chemistry remains poorly characterised.
Could the discovery of rare flavoalkaloids in cannabis leaves revolutionize future medical treatments and reshape the value of plant waste?
How might these newly found compounds in cannabis leaves challenge current pharmaceutical approaches and influence the future of precision medicine?
Discovery of 16 Novel Flavoalkaloids in Cannabis Leaves Reveals Untapped Therapeutic Potential
Overview
In 2025, researchers at Stellenbosch University used an advanced two-dimensional liquid chromatography method with high separation power to analyze cannabis. This breakthrough technique allowed them to identify 16 new flavoalkaloid compounds and 25 other phenolic substances, mainly in the leaves of one strain. This discovery challenges the traditional focus on cannabinoids and highlights the medicinal potential of cannabis leaves, previously considered waste. It opens new opportunities for therapeutic development and encourages the cannabis industry to repurpose leaves for valuable compound extraction. Future research will focus on fully understanding these compounds and enhancing their production, showing that even well-studied plants can reveal surprising secrets with advanced technology.
