"The volatile oil of the leaves of Pogostemon heyneanus Benth. (Lamiaceae) was analyzed by GC and GC-MS. Twenty-six components representing 96.0% of the oil were identified. The major components of the oil were acetophenone (51.0%), beta-pinene (5.3%), (E)-nerolidol (5.4%), and patchouli alcohol (14.0%). Comparison of the compositions of the oils of P. heyneanus and P. cablin (Blanco) Benth. (Patchouli oil) showed wide variation between them. Though 13 sesquiterpenes and oxygenated sesquiterpenes were detected in both oils, their concentrations in the oils differed widely. Acetophenone, benzoyl acetone and (E)-nerolidol present in the oil of P. heyneanus were not detected in patchouli oil." \\

Main constituents of P.heyneanus essential oil were α-pinene (3.1%), β-pinene (11.9%), acetophenone (14.5%), β-caryophyllene (9.2%), seychellene (1.8%), α-guaiene (2.9%), α-humulene (1.1%), α-patchoulene (1.3%), δ-guaiene (1.8%), (E)-nerolidol (18.8%), and patchoulol (13.2%). Minor components were e.g. limonene, geranial, bornyl acetate, β-ionone, farnesol, serratol and incensol. \\
