The oils were produced in light- yellow colors at the yields of 060%, 0.14% and 0.50%, respectively (based on fresh weights). The oils were analyzed by CGC-FID and GC/MS. Thirty-four compounds were identified in each one among which 1.8-cineole (48.8%, 1.0% abd 2.5%) p- cymene (16.3%, 35.5% and 23.9%) and spathulenol (3.7%, 2.7% and 15.4%) were the major constituents, respectively.

F.) Jalas and T. serpyllum L. were collected from different regions at before flowering and full flowering stage. The air-dried aerial parts of these species were steam distilled for obtaning their essential oils. The oil yields are as follow respectively: at before flowering (0.66%, 0.28%, 0.26%, 0.55% and 0.57%) and at full flowering stage (0.86%, 2.1%, 0.43%, 1.45% and 0.90%). Totally the oil yields were lower for theses Thymus species before flowering. The highest oil yields were obtained from T. kotschyanus and T. pubescens. Analysis and identification of chemical composition of the oils were performed by GC and GC/MS. Thirty-seven components (representing 93.1%-98.3% of the oils) at before flowering stage and thirty-nine components (representing 88.2%-99.3% of the oils) at full flowering stage were identified. The main components of the oils were as follow, before and full flowering stage, respectively: T. carnosus, thymol (27.2% and 36.1%), g-terpinene (19.6% and 19.1%), p-cymene (26.2% and 21.3%), b-caryophyllene (2.5% and 2.8%), carvacrol (2.2% and 2.5%) and borneol (1.6% and 1.6%).

The aerial parts of Thymus pubescens were collected from three various localities of Lar valley (in East of Tehran province). Essential oils isolated by steam distillation from the plant material at two stages, before flowering (BF) and full flowering (FF). Yields of essential oils were 0.53% to 0.93% (at BF stage) and 1.23% to 2.03% (at FF stage). Therefore the oil content at BF stage was less than FF stage. At BF stage 26 compounds (representing 98% to 99.3% of the oils) and at FF stae 32 compounds (representing 97.7% to 98.5% of the oils) were characterized. Major constituents at BF stage were: carvacrol (52.6% - 77.9%), thymol (2.7%-21.8%), g-terpinene (3.3%-7.4%), p-cymene (2.2%-4.4%), and b-caryophyllene (1.7%-2.5%). Major constituents at FF stage were: carvacrol (54.7% - 69.2%), p-cymene (6.7%-9.7%), borneol (1.7%-5.1%), methyl carvacrol (0.6%-6.6%) and 1,8-cineol +limonene (1.7%-3.2%). Twenty-three constituents were common at two stages. d-cadinene, thymyl acetate and g-muurolene (E)-b-ocimene were found just at BF stage and a-phellandrene, a-terpineole, terpinen-4-ol, spathunelol, camphor, linalool, methyl linalo, methyl thymol, thymoquinone and thymodihydroquinone were found just at FF stage.

Five irrigation treatments determined that consisted of (i) a control which was irrigated to full field capacity during the growing season (FC), (ii) two moderate water stress treatments during vegetative (LS1) and flowering stages (LS2) and (iii) severe water stress treatments during flowering stages (HS). The volatile constituents of the aerial parts of cultivated S. hortensis were isolated by steam distillation and analysed by GC/MS. Result showed that the oil acclimation under greater soil water stress increased significantly especially in severe treatment. This treatment at the flowering stage affected on the quantity of the essential oils more than the moderate stress in vegetative and flowering stages. The main oil constituents were carvacrol [44.5% (LS2), 42.6% (LS1)] and g-terpinene [40.9% (FC), 37.8% (HS)]. The amount of carvacrol increased under two moderate stresses but g- terpinene content decreased after moderate and severe stress.

The percentage of oil from flower 0.07% and root 0.06% are calculated, and analysed by GC and GC/MS. The main components for flower by steam distillation Oplopenone (19.1%), a-Cadinol(5.5%), T-Cadinol(4.9%), S Cadinene (4.5%), and Curdione (4.2%) and by Hydrodistillation Globulol (7.2%), Cadalene (7.0%), S-Cadinene (6.7%), Torreyol (6.1%) and Oplepenone (5.1%). The main components for root by hrdrodistillation are Alantolactone (24.9%), Spathulenol (10.8%), (E-E)-Farnesol (8.1%) and Ledol (7.4%).

Comparative study of the essential oil composition of Satureja hortensis L. by hydro and steam distillation methods

M. Mirza; L. Ahmadi

Volume 7, Issue 1 , April 2001, , Pages 55-70

Abstract

  Essential oil of Satureja hortensis was isolated from shoots at flowering stage by two steam and hydrodistillation methods. Both of essential oil were analysed by GC-MS. Twenty-six components were identified representing 99.6% of the oils. The major components being y-terpinene (38%, 47%), Carvacrol ...  Read More Essential oil of Satureja hortensis was isolated from shoots at flowering stage by two steam and hydrodistillation methods. Both of essential oil were analysed by GC-MS. Twenty-six components were identified representing 99.6% of the oils. The major components being y-terpinene (38%, 47%), Carvacrol (45%, 30%), P-cymene (3.2%, 0.2%) and a-terpinene (2.6%, 5.7%) by twohydro and steam distillation methods, respectively. carvacrol and y-terpinene showed no marked difference by the mentioned methods.

About two million hectars of Iran, mostly on west and northwest, are suitable for Baneh cultivation and rehabitation. In this research samples are collected on july 1998 from Khojeer park which are in east of Tehran and the essential oils from fresh leaves obtained by steam distillation method and fruit sample by hydrodistillation method. The percentage of oils from female leave was 0.04% and for male was 0.07% and for fruit was 0.58% calculated on the fresh weight. The essential oils were analysed by capillary CC and GC/MS on DB-1 column. The major constituents for female leave were a-pinene (21.7%), 7-cadinene (19.3%), and myrcene (4.7 %), and for male leave were a-pinene (36.2%), y-cadinene (17.9 %) and B-pinene (6.3%) and for fruit were a-pinene (73.6 %), B-pinene (5.3 %), myrcene (3.3%) and camphene (2.3%)

K. Jaimand; M.B. Rezaee; G.R. Nabi

Volume 6, Issue 1 , September 2000, , Pages 13-27

Abstract

  The genus of Mentha is one of the most important of medicinal plant which is used in pharmaceutical and food industries. Cultivated Mentha piperita L. were collected from two different locations, one from Karaj city, Kalak (sample 1) at the beginning of June 1998 and other sample from Kamoo village 70 ...  Read More The genus of Mentha is one of the most important of medicinal plant which is used in pharmaceutical and food industries. Cultivated Mentha piperita L. were collected from two different locations, one from Karaj city, Kalak (sample 1) at the beginning of June 1998 and other sample from Kamoo village 70 Km away from Kashan city (sample 2) at the beginning of June 1999, and essential oils were obtained from leaves by steam distillation method. The oil yields of two samples were 1% v/w calculated on the weight of fresh plant. The oils were analyzed by capillary GC and GC/MS. Main components from sample 1 representing 93.55% of total oil were, Neo-menthol (42.62%), 1,8-Cineole (16.81%) and piperitone (12.25%), and for seconed sample, main components are L-menthol (37.55%), L-menthone (19.13%), 1,8-Cineole (11.48%) and Menthofuran (4.45%).
