Abstract: Five flavonodis were isolated from the stem of Desmos chinensis Lour., of wich three were identified as desmethoxymatteucinol(II),negletein(III) and lawinal(IV) respectively.The structure of new dihydroflavone named cochinine A,was elucidated as 5-hydroxy-6-fromyl-7-methoxy-8-methyl dihydrflavone (I) by means of spectroscopic analysis.The chemotaxonomy feature of these flavonoids was also approached.

Key words: Annonaceae, Desmos ckinensis
