These values are at odds with the current British and European Pharmacopoeia values of up to 0.1% (1000 ppm).

Notes on the composition of patchouli oil (Pogostemon cablin (Blanco) Benth.) / Charles P. Cornwell in The journal of essential oil research, Vol. 22 N° 4 (Juillet/Août 2010)  

Public ISBD [article]  inThe journal of essential oil research > Vol. 22 N° 4 (Juillet/Août 2010) . - pp. 360-364 Titre : Notes on the composition of patchouli oil (Pogostemon cablin (Blanco) Benth.) Type de document : texte imprimé Auteurs : Charles P. Cornwell, Auteur Année de publication : 2011 Article en page(s) : pp. 360-364 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Pogostemon cablin Lamiaceae Essential oil composition Allo-aromadendrene Index. décimale : 646 Résumé : A study of commercial oils of Patchouli [Pogostemon cablin (Blanco) Benth.] from three regions in Asia found no evidence for the presence of allo-aromadendrene in any of the oils, indicating that previous reports were either adulterated with Gurjun Balsam (Dipterocarpus sp.) or more likely misidentified. Traces of acetophenone, 9-epi-β-caryophyllene, (E)-4,8-dimethylnona-1,3,7-triene, (E,E)-farnesol, (E,E)-farnesyl acetate, hexahydrofarnesyl acetone, isovaleric acid, 2-methylbutyric acid, 5-methylfurfural, 1-octen-3-one, 2-pentylfuran, phenylacetaldehyde, phytol, toluene, and p-vinylguaiacol were identified, possibly for the first time, in Patchouli oil.
