Chemical investigation of the leaf and rhizome essential oils of Zingiber zerumbet (L.) Smith from Bangladesh

“…But it is very interesting to note that comparison of our results reported on the leaf oil composition from the different places showed different results in the percentage content of some of the major and minor constituents. Zerumbone and -caryophyllene, which have been reported as major constituents in our oils as well as in almost all the leaves and rhizomes oils of the world (Vahirua et al, 1993;Dung et al, 1993;Chane et al, 2003;Srivastava et al, 2000;Chhabra et al, 1975;Duve, 1980;Nigam and Levi, 1963) were either absent or present in trace amounts in the oil reported. This confirms that the variations in the cultivar reported are not due to geographic divergence and ecological conditions but that is due to different chemotype than ours.…”

“…The characteristics of the oils from the leaves and rhizomes of Z. zerumbet allow them to be identified unequivocally. Lechat-Vahirua et al (1993) reported also the presence of zerumbone (65.3%) as major compounds in the oil from French polynesia. There are no previous references in literature about these Bangladeshi oils.…”

Chemical Constituents of the Root Essential Oils of <i>Zingiber rubens</i> Roxb., and <i>Zingiber zerumbet</i> (L.) Smith

“…For example, its contents from sample of India origin varied from 76.3% -84.8% while the oil from Malaysia had a content of 68.9% [5]. Another sample from India has zerumbone content of 12.6% [11] while the rhizomes oils from Reunion Island [13] and French Polynesia [12] contained 37.0% and 63.0% of zerumbone respectively. However, there are reports in which other terpenoid compounds have predominated in the oils ( Table 2).…”

“…Essential oils from various parts of Z. zerumbet have been analysed. The investigations revealed that the content of its predominant compound, zerumbone, varied from one geographical location to another [5,[9][10][11][12][13][14]. For example, its contents from sample of India origin varied from 76.3% -84.8% while the oil from Malaysia had a content of 68.9% [5].…”

Zerumbone, a Natural Plant Dietary Compound Induces Expression of Interleukin-12p70 Cytokine in Human Peripheral Blood Mononuclear Cells

“…Zerumbone, a naturally occurring nutritional compound is a monocyclic sesquiterpene found in large quantities in rhizome of Zingiber zerumbet Smith [1,2] and is present in many natural foods we consume. Its structure possesses three double bonds, two conjugated and one isolated, as well as double conjugated carbonyl group in the 11-membrane ring structure [3] and has been found to possess many biomedical properties such as antiproliferative, antioxidant, antiinflammatory [4][5][6], anticancer [7][8][9][10], and antimicrobial [11][12][13] activities.…”
