Volatile constituents ofNepeta glomerulosa Boiss. subsp.carmanica

Abstract

The constituents of the essential oil obtained by the hydrodistillation of Nepeta glomerulosa Boiss. subsp. carmanica were investigated by GC and GC–MS analysis. The oil contains over 35 components. The major components were α‐pinene (18.3%), 1,8‐cineole (13.9%), limonene (9.7%), linalool (4.8%), trans‐β‐ocimene (4.7%), humulene epoxide (4.2%), trans‐α‐bergamotene (3.5%), α‐humulene (3.2%) and camphene (3.1%). Identification of the compounds was based on retention indices, MS data and comparison with authentic samples. Copyright © 1999 John Wiley & Sons, Ltd.

Essential oil composition of Nepeta satureioides from Iran

“…Kopetdaghensis [3], N. makuensis [4], N. fissa [5], N. glomerulosa [6], N. macrosiphon [7], N. heliotropifolia [8], N. denudata [9], N. glomerulosa subsp. carmanica [10], and N. ispahanica [11]. Iran.…”

Chemical Constituents of the Essential Oil of Nepeta oxyodonta

“…is a herbaceous wild plant endemic to Iran [2], and no phytochemical studies on this plant have yet been carried out. In continuation of our investigations on the chemical composition of the essential oils of various Nepeta species growing in Iran [15,16], the chemical composition of the essential oil from N. oxyodonta is reported for the first time.…”

“…However, there are Nepeta spp. poor in nepetalactones [13,14], and some may even contain no nepetalactones [15][16][17][18][19][20][21][22][23][24].…”

“…Generally, the genus Nepeta, according to the presence or absence of nepetalactones in their oils, could be classified into two groups. Nepetalactones are absent in the oils of some Nepeta species [15][16][17][18][19][20][21][22][23][24]. As can be seen in Table 1, nepetalactones were not also detected in the oil of N. oxyodonta.…”

Essential Oil Composition of Nepeta involucrata from Iran

“…No traces of nepetalactone isomers were found as the oil constituent in N. glomerulosa subsp. carmanica [19], N. ispahanica [18], N. denudate [12], N. heliotropifolia [20], N. glomerulosa [21], N. fissa [22], and N. macrosiphon [23]. 1,8-Cineol was found to be the principal component of some other Nepeta species such as N. ispahanica (65.2%), N. binaludensis (42.3%) [18], N. denudate (48%) [12], N. heliotropifolia (19%) [20], and N. crispa (47.9%) [24].…”
