%X Two new diterpenes have been isolated from the twigs of Ryparosa acuminata ( Flacourtiaceae ), and identified as 16&#945;,19-dihydroxykauran-20-oic acid &#948;- lactone and 16&#945;-hydroxykaurane-19,20-dial. Friedelin and eudesmin were also isolated. The structure of the lactone was confirmed by X-ray crystallography.
