| Experiment Detail |
Populations of A. annua cultivar 'Jeevanraksha' and accession Suraksha were grown in the experimental field plot of the Institute at New Delhi. The seeds were sown in January 2004, seedlings transplanted in late February 2004 and aerial parts (flowers, leaves and stems from the upper 0.5 m of crop canopy) sampled in late October 2004.

| Factor Function |
Ninety-seven compounds comprising 91.3% of the total oil of 'Jeevanraksha' were identified. Forty-three monoterpenes (56.6%), 32 sesquiterpenes (31.1%), and 2 diterpenes (0.2%) comprised bulk of the oil (87.9%). The oil was devoid of artemisia ketone and contained camphor (13.5%), 1,8-cineole (9.4%), trans-sabinol (7.1%), p-mentha-1(7), 5-dien-2-ol (6.3%), myrcene (4.7%), germacrene D (4.4%), (E)-beta-farnesene (3.9%), beta-caryophyllene (3.7%), dihydroartemisinic lactone (3.0%) and p-cymene (2.0%) as the major constituents. Eighty-six compounds representing 93.3% of the composition were identified in the Suraksha oil. This oil contained artemisia ketone (47%), 1,8-cineole (8.4%), camphor (5.9%) and alpha-pinene (5.2%) as the major components.

| Species Name: Coriandrum sativum | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Factor Name: Locality Variation | [2] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Experiment Detail |
Two samples (20 kg each) of mature coriander (Coriandrum sativum L.) fruits were used for this study. The first was purchased from a spice market of Korba in Tunisia (Tn), the second, from Canada (Can), was supplied by General Herboristerie Laboratory (Marseille, France).

| Factor Function |
The first from Tunisia (Tn) and the second from Canada (Can). The highest essential oil yield was observed for Can with 0.44% (w/w) and 0.37% (w/w) for Tn. Forty-five compounds were identified in the essential oils and the main compound of both samples was linalool. The total phenol contents varied between two coriander fruit samples; Can sample presented high polyphenol contents (15.16 mg GAE/g) compared with Tn one (12.10 mg GAE/g). Significant differences were also found in total tannin contents among representing 0.7 mg GAE/g in Can and 0.34 mg GAE/g in Tn. The highest contents of total flavonoids were observed in Can sample with 13.2 mg CE/g.

| Factor Name: Month Variation; Nitrogen Treatment; Phosphorus Treatment; Potassium Treatment | [3] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Experiment Detail |
The plants were cultivated in the Botanical Garden of the University of Agriculture, Plovdiv/Bulgaria on meadow-carbonate soil with neutral reaction (pH 7.1-7.2) and were harvested during the flowering period (July and September). The reserves of nitrogen, phosphorus and potassium in the soil (NPK) were: NH4+ 31.42 mg/kg; NO3- 16.66 mg/kg; P2O5 12.3 mg/100 g and K2O 11.4 mg/100 g. Ammonium nitrogen and nitrate nitrogen were extracted from the soil with a 1% solution of KCI and were determined by consecutive distillation on a Parnas-Vagner apparatus. Phosphorus was determined by the Egner-Ream method and potassium was extracted with 2 n HCI and was determined by flame photometry. The plants were grown as seedlings and were planted in a two-row bed 50 × (20 + 20) cm in patches of 5 m2. A scheme on the increase was used for the introduction of N, P and K fertilizers. The experiment was carried out as a randomized block modus - 15 variants in 4 replications (6 levels for N and 4 levels for P and K). Phosphorus (triple superphosphate - 50 % active substance) and potassium (potassium sulphate - 50 % active substance) were introduced only once before planting. Nitrogen (the ammonium nitrate - 33 % active substance) was introduced in three portions - during preparing of the soil, during the plants drafting (active vegetation) and at the full bloom.

| Factor Function |
The highest oil yield was obtained from leaves in July for N4P2K4 (0.63%) and the basic components were piperitenone (29.4%) and piperitone (13.5%). The mineral fertilization had no effect on the oil yield from the flowers. Regardless of the variant, it was found that the flower oils in July were rich in caryophyllene oxide (12.0-48.4%) and piperitenone (3.0-7.0%), while the oil composition in September was different.

| Factor Name: Locality Variation | [4] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Experiment Detail |
Aerial parts of T. larvatum were collected in July and August during a five-year period, starting in 2001, in Montenegro on several locations: Planinica (Sample a), Visitor (Sample b) and Sinjajevina (Sample c).

| Factor Function |
Sixty-four components were identified, representing 83.1%, 96.6% and 89.4% of the total oils content in the Planinica [Sample a], Visitor [Sample b] and Sinjajevina [Sample c], respectively. The major constituent in Samples a and b , was oxygenated monoterpene, trans-sabinyl acetate (38.1% and 55.8% respectively). Monoterpene hydrocarbons, beta-pinene (13.5%) and santolinatriene (30.6%), were found to be the dominant components in Sample c. The toxic trans-sabinyl acetate was present only in traces in this sample. trans-Chrysanthenyl acetate, as one of major components in feverfew essential oil, has not been previously identified in the investigated essential oils.
