The new ingenane diterpene, 5-deoxy-13-hydroxyingenol, was isolated from the alcohol preserved fresh latex of the stems of Mabea excelsa and characterized from its semi-synthetic triacetate. This is the first instance of an ingenane diterpene obtained from species other than those of Euphorbia and Elaeophorbia. This diterpene occurred in the latex in the form of an inseparable mixture of six aliphatic mono-esters of the tertiary C-13 hydroxy group.
