title: A cleistanthane diterpene lactone from Vellozia compacta.
abstract: 8,11,13-cleistanthatrien-7-one-19,20 beta-olide and six other previously described diterpenes were isolated by silica gel chromatography of the ethyl alcohol extract of Vellozia compacta. The structure of the cleistanthane lactone was deduced on the basis of spectral data analysis.
