pseudolimon essential oil whereby the main constituents were limonene
(47.07%), cuminal (11.41%), eugenol (10.17%), b-pinene (5.23%), styrene glycol (3.49%), -terpinene (3.67%), 3-isobutyl-1-cyclohexene (2.57%), caryophyllene (2.04%), menthene (1.53%), a-pinene (1.01%), p-cumic aldehyde (1.47%), a- isopropylbenzyl alcohol (1.56%), caryophyllene Oxide (1.94%) and Eugenyl acetate (1.29%).
Thereafter, the leaf and berry essential oil compositions from various mediterranean origins have also been investigated such as in Turkey (Ozek et al., 2000), France (Bradesi et al., 1997), Italy (Pirisino et al., 1996), Portugal (Boelens and Jimenez, 1991), Spain (Boelens and Jimenez, 1992), 1,8-cineole (18.3%), linalool (16.3%) and myrtenyl acetate (14.5%), limonene
(5.7-43.4% and 6.2-44.2%), 1,8-cineole (5.9-26.6% and 8.7-30.40%), respectively.
encapsulation in freeze-drying of gum Arabicsucrose-gelatine systems.
Chemotaxis of adult psyllids to volatile terpenes Obviously non significant percentage of female psyllids showed chemotaxis to individual tested terpenes of limonene
(P=0.80183) or AY- pinene (P=0.84361) (Table II).
Of the 30 listed compounds, the following had the highest percentages: [alpha]-pinene (20.58% to 10.91%), camphene (22.38% to 2.86%), [beta]-pinene (6.73% to 3.96%), [beta]-myrcene (1.09% to 2.51), [delta]-[beta]-carene (4.36% to 16.77%), [alpha]-terpinene (0.9% to 4.22%), [beta]-phellandrene (0.00% to 13.36%), limonene
(20.16% to 0.00%), terpineol (0.33% to 5.35%), and bomyl acetate (9.79% to 0.68%).
The effect of pH on limonene
biotransformation was studied by dissolving YM culture medium in a 0.1 M HCl at pH values of 2.5, 4 and 5.5 and also a 0.1 M NaOH at pH values of 7.5, 10 and 12.5.
However, when R-limonene is oxidized, it includes limonene
hydroperoxides, which Dr.
haworthi revealed the presence of the monoterpenes [alpha]-pinene, [beta]-pinene, myrcene, and limonene
, which were identified by comparison of those of authentic reference samples (Figure 1, Table 1).
Ashraf et al  analyzed the dill seed essential oil by GLC and found the oil to be rich in carvone (52.25%), dill apiole (28.28%) and limonene
The chromatographic analysis carried out for the essential oil allowed the identification of citral (neral + geranial isomers) in the AndrE da Rocha population, ledene and caryophyllene in Bom Jardim da Serra and limonene
, borneol, 1,3,8-menthatriene and 1,5,8 p-menthatriene in Santa Lucia as major compounds.
