Zerumbone is a sesquiterpene phytochemical with potential anticancer, anti‐inflammatory, anti‐HIV and other biological activities, most abundantly found in Zingiber zerumbet (L.) Smith. Previous studies reported 12.6–73.1% of zerumbone in Z. zerumbet rhizome oils from various geographical locations. In a careful review of the literature, we found that most of the previous gas chromatographic profiling studies on volatile oils of Z. zerumbet were inadequate, since they were based on poor identification and quantification procedures and also on single‐sample data. In this study, we report the chemical profiles of volatile oils of Z. zerumbet rhizomes from six locations in the southern Indian state of Kerala and also from Penang in Malaysia. Chemical profiling of volatiles was carried out by extensive GC–FID, GC–MS and associated techniques, supported by 1 H‐NMR, 13 C‐NMR, FABMS and HPTLC. The full chemical profiles of rhizome oils of these seven accessions of Z. zerumbet were elucidated. The south Indian accessions of Z. zerumbet reported 76.3–84.8% zerumbone content in their rhizome oils. The Malaysian accession recorded the lowest content of zerumbone (68.9%). This study reveals the high content of the bioactive compound zerumbone in Z. zerumbet from Kerala. Copyright © 2009 John Wiley & Sons, Ltd.
