[Progress in study of flavonoids from Annonaceae and biological activities of these compounds].

More than 50 new flavonoids derived from Annonaceae are reported in the last two decades. Many genuses in Annonaceae contain flavonoids having structural novelty and broad pharmacological activities. Due to the pharmacological interest of some of these compounds, chemical investigations on this topic have grown considerably in the decades. Here the biological activities of some of these flavonoids are also briefly discussed.
