Pyranochromanone acids isolated from Calophyllum species have shown a variety of biological potentialities including antioxidant, antiulcer, anticancer and anti-Helicobacter pylori activities. These compounds seem to be the main constituents of Cuban Calophyllum species together xanthones and biflavonoids. Recently, the pyranochromanone acids calophyllic(More)
The genus Garcinia is a source of a large variety of organic compounds including biflavonoids, acylphloroglucinols and xanthones mainly, but few data are available about the chemical composition of Cuban species. The aim of this investigation was to identify the main constituents of G. bakeriana Urb., a rare Cuban endemic plant. A new biflavonoid,(More)
