The essential oil from the leaves of Phyllanthus acidus (Phyllanthaceae) was obtained by hydrodistillation and its composition determined by GC and GC/MS. Twenty-one compounds were identified, representing 92.8 % of the oil. The most abundant components were t -muurolol (20.4 %), α-cadinol (14.6 %), β-cadinene (8.9 %) and α-muurolene (7.5 %).
