Don’t toss cannabis leaves: Scientists found rare compounds with medical potential | ScienceDaily Science News from research organizations Don’t toss cannabis leaves: Scientists found rare compounds with medical potential Cannabis just revealed a hidden chemical treasure—rare compounds scientists never knew were there. Date: May 1, 2026 Source: Stellenbosch University Summary: Scientists have uncovered a surprising new layer of complexity in Cannabis, identifying dozens of previously unknown compounds—including the first-ever evidence of rare molecules called flavoalkaloids in its leaves. These compounds, prized for their potential health benefits, were hidden among a rich mix of plant chemicals that vary dramatically even between just a few strains.

The breakthrough reveals hidden medicinal potential in parts of the plant often ignored.

Phenolic compounds, particularly flavonoids, are already highly valued in medicine for their antioxidant, anti-inflammatory, and anti-carcinogenic effects. This new finding suggests Cannabis may contain even more biologically important compounds than previously recognized. Dozens of Previously Unknown Cannabis Compounds Identified In their study, researchers analyzed three commercially grown Cannabis strains from South Africa and identified 79 phenolic compounds. Of these, 25 had never before been reported in Cannabis . Among them were 16 compounds tentatively classified as flavoalkaloids, a group that is rarely found in nature. Interestingly, these flavoalkaloids were concentrated mainly in the leaves of just
