title: Three new diterpenoids from Mallotus apelta Muell.Arg.
abstract: Three new diterpenoids, 10-hydroxy-cembrene-5-one, 6-hydroxy-cembrene-5,10-dione and 2alpha,4beta,15,16-tetrahydroxyl-dolabradane were isolated from the petroleum ether fraction of the alcoholic extract of Mallotus apelta Muell.Arg. Their structures were determined by spectral methods.
