Description Accepted date: 29 August 2013
A set of 84 accessions of turmeric Curcuma longa L. collected from various geographical locations in northern India were
assessed for variation in morphological features, leaf and rhizome essential oil content, yield and quality, curcumin content
in rhizome and curcumin yield and potential for curcumin extraction from rhizomes, following their distillation for essential
oil extraction. Large variability was recorded in all the features studied.
The accessions demonstrated wide variation in the contents of -terpenene, 1, 8-cineole and -cymene in the leaf essential
oils and of pinene, myrcene, Ar-curcumene and turmerones in the rhizome essential oils. There were some accessions
which were highly deficient in one or more terpenoids in their leaf and/or rhizome essential oil. The leaf oils of the
accessions CH-2 and CH-3, CH-15, CH-38, CH-40 and CH-53 were deficient in -cymene and Ar-turmerones, Ar-curcumene
and Ar-turmerone, Ar-turmerone and -turmerone, Ar-curcumene and Ar-turmerone and -turmerone and Ar-curcumene
and all turmerones, respectively. The rhizome essential oil of the accession CH-14 was highly rich in turmerones and that
of CH-99 was deficient in turmerones, respectively. The accessions CH-6, CH-11 and CH-19 were identified as high
yielding elite resource for both curcumin and leaf oil. The possibility of profitable extraction of curcumin from the essential
oil extracted rhizomes was demonstrated.
