Objectives: The incidence of cancer, a second leading cause of death globally, continues to rise steadily, and could reach 28.4 million cases by 2040, if no action is taken. Prostate cancer, the second most common cancer in men globally following lung cancer, accounted for 1,414,259 new cases and led to 375,304 deaths in 2022.

Propolis is a resinous material collected by different bee species from various plant exudates and used to seal holes in honeycombs, smoothen the internal walls, embalm intruders, improve health and prevent diseases. From its -hexane extract, eight compounds were isolated and characterised as: mangiferonic acid (); 1-hydroxymangiferonic acid (), new natural product; mangiferolic acid(); 27-hydroxymangiferolic acid (), reported here for the first time as propolis constituent; 27-hydroxymangiferonic acid (); -amyrin (); -amyrin () and lupeol (). The chemical structures of the isolated compounds were elucidated using spectroscopic methods, such as 1D and 2D-NMR, mass spectrometry and comparison with previous published reports.

Article Synopsis
  • A new diterpenoid called rubesanolidic acid was discovered alongside six known compounds from the roots of a particular plant using column chromatography.
  • Their structures were confirmed through various spectroscopic analyses and comparisons with prior research data.
  • The extract showed significant -amylase inhibition activity, outperforming individual compounds, with rubesanolidic acid displaying the highest inhibition among the isolated compounds, suggesting the plant has potential as a source for antidiabetic agents.
