Abstract Three labdane-typediterpenes; 3-oxo-marrubiin and a mixture of two related C-15 epimeric diterpenes based on 9α,13α,15,16-bisepoxy-15-hydroxy-3-oxo-labdan-6β, 19-olide, in addition to the acylated flavone apigenin 7- O -[6″- O -( p -hydroxy- trans -cinnamoyl)glucoside] were isolated and identified from the aerial parts of Leucas neufliseana . Their structures were established through physical
