In a promising scientific step that may change our perception of the daily cup of coffee, a research team from the Kunming Institute of Botany of the chinese Academy of Sciences has discovered three wholly new chemical compounds in roasted Arabica coffee beans, which have a strong ability to inhibit the alpha-glucosidase enzyme, which is responsible for breaking down carbohydrates in the intestines and converting them into glucose that the body absorbs quickly.
Superior results to Common Diabetes drugs

Researchers have named these new compounds cavaldelhydes A, B, and C, which are diterpene esters containing an aldehyde group. Laboratory tests have shown that these compounds effectively inhibit the enzyme, surpassing the effectiveness of acarbose, a commonly used drug for treating type 2 diabetes.
Inhibiting the alpha-glucosidase enzyme is a essential mechanism in diabetes medications, as it slows the absorption of glucose into the bloodstream after consuming carbohydrate-rich meals, helping to prevent sharp spikes in blood sugar levels, known as “postprandial hyperglycemia.”
the Secret is in the Roasting
Researchers explained that the roasting process plays a crucial role in forming these active compounds, as they were not discovered in green coffee beans with the same effectiveness. The team also used an activity-guided research strategy to efficiently identify the active compounds.
Roasted Coffee Compounds Show Promise in Diabetes Treatment
Researchers at the University of Jinan, China, identified compounds in roasted coffee beans that demonstrate a greater ability to inhibit α-glucosidase and α-amylase – enzymes linked to type 2 diabetes - than current pharmaceutical treatments, according to a study published January 21, 2026, in the Beverage Plant Research journal.
Study Details
Professor Minghua Qiu led the research team. They used nuclear magnetic resonance spectroscopy and high-performance liquid chromatography to extract and analyze bioactive compounds from roasted coffee beans. The study focused on identifying compounds with potential anti-diabetic properties.
The research revealed that specific compounds present in roasted coffee exhibited a stronger inhibitory effect on α-glucosidase and α-amylase than acarbose, a commonly prescribed medication for type 2 diabetes. The study did not specify the exact compounds, but indicated they were previously unknown.
Implications
These findings suggest roasted coffee could offer a novel, natural approach to managing type 2 diabetes. Further research is needed to isolate and test these compounds in clinical trials to determine their efficacy and safety in humans.
