Chemical Composition of the Essential Oil from the Leaves ofCurcuma zedoariaRosc. of Indian Origin

Analysis of volatile components of Curcuma sichuanensis X. X. Chen by gas chromatography–mass spectrometry

“…The total percentage of the sesquiterpene group (85.4%) was more than 55 times higher than that of the monoterpene group (1.5%), indicating that the sesquiterpene was the dominant group in the essential oil of C. sichuanensis X. X. Chen. The result was comparable to those reported previously [7][8][9][10][11][12][13][14].…”

“…have been reported [11,12]. ␣-Terpinyi acetate (8.4%), isoborneol (7%), dehydrocurdione (9%) and selina-4(15),7(11)-dien-S-one (9.4%) were determined as the major constituents of the essential oil in Curcuma zedoaria (Zingiberaceae) leaves [11]. The leaf oils of Curcuma caesia Roxb.…”

Isolation and Characterization of Antioxidation Enzymes from Cells of Zedoary (Curcuma zedoaria Roscoe) Cultured in a 5-l Bioreactor

“…Zedoary essential oil evidences antimicrobial and antimutagenic activities. The constituents of zedoary rhizome oil have been investigated extensively, and zedoary has been recognized as a rich source of terpenoids [1,2]. Curcumin is renowned for its antitumor, antioxidant, antiamyloid, and antiinflammatory properties.…”

<I>Curcuma zedoaria</I> Rosc. (white turmeric): a review of its chemical, pharmacological and ethnomedicinal properties

“…[16] Mau et al [17] isolated essential oils from the rhizomes. They isolated a total of 36 compounds but were only able to structurally characterize epicurzerenone (19) and curzerene (20).…”

“…The major constituents of the leaf oil were a-terpinyl acetate (8.4%), isoborneol (7%) and dehydrocurdione (9%). [20] Chemical analysis of the volatile oil from C. zedoaria using GC-MS technique revealed the presence of b-tumerone (19.88%), 1,8-cineole (8.93%) and zingiberene (23) (7.84%) as major constituents. [21] The essential oil of the dried rhizome was isolated using simultaneous steam distillation and solvent extraction and its fractions were prepared by silica gel column chromatography.…”
