Coriander Seed

Coriandrum sativum L. belongs to the Apiaceae family, which is cultivated in Dong Nai province, in this paper its seed oil of was studied. The essential oil was extracted by hydrodistillation. We used two methods for activating of hydrodistillation: conventional heating and microwave irradiating. Its physical and chemical indexes were measured. The chemical composition of this oil was identified by GC/MS and quantified by GC/FID. Linalool (75.51-77.21 %), and geranyl acetate (15.64-12.79 %) were the main constituents of the oil which were obtained in 0,32-0.39 % yield. The biological activity of this oil was reported.

Investigation of the chemical composition of Cananga odorata(Lam.) leaves and essential oil in Ben Tre Province was conducted with steamenticing distillation method, extraction nhexane and Soxhlet with the solvents of nhexane, dietyl ether respectively. The results have determined the distillation conditions and the content of Cananga odorata (Lam.) essential oil by fresh weight and water volume is: 1: 3 (gram / ml)with distillation time: 3 to 4 hours. The content essential oil of Cananga odorata (Lam.) flower obtained in dry weight is 1.10% -1.26% and in fresh weight is 0.56% - 0.65%. The results of the study identified some physical and chemical indexes: the essential oil of Cananga odorata (Lam.) flower in Ben Tre is yellow, clear, has a stronger aroma and is lighter than water; Physical and chemical indices of the essential oil of Cananga odorata(Lam.) flower measured in three different lands of Ben Tre and collected during the same period showed: The density changed from 0.92 - 0.95; Refractive index varies from 1.4952 - 1.4991; The acid index varies from 0.13 to 0.38; The ester index ranged from 37.55 to 38.11; The saponification index ranged from 37.67 to 38.49. Mass SpectrometryMS method has been identified that the main chemical composition the essential oil of Cananga odorata (Lam.) flower in three regions are consistent with the results of the authors who have studied theessential oil of Cananga odorata (Lam.) flower in the North and include the following components: L-linalol, geraniol, geranyl axetat, benzyl benzoat, anđehit benzoic, etyl benzoat, D-germacren,... In which, the main ingredents of Cananga odorata (Lam.) flower in n-hexane extract are: benzyl benzoate, D-germacren,L-linalol, b-caryophyllen; The main components when make in dietyl ether are: benzyl benzoate, geranyl acetate, anisyl acetone, D-germacren; The main ingredients of Cananga odorata (Lam.) leaf inn-hexane extract include: L-linalol, transgeraniol, geranyl acetate,...From n-hexane solvent extract, we isolated, purified and determined the structure of the crystalline solid is benzyl benzoate.

The chemical composition of the essential oil from the rhizome of ginger ( Zingiber officinale Roscoe), collected from Nahan, Himachal Pradesh, India, was determined by gas chromatography and GC-MS. Fifty-one compounds, representing 95.1% of the oil, were identified. The oil was characterized by relatively large amounts of the monoterpenoids 1,8-cineole (10.9%), linalool (4.8%), borneol (5.6%), α-terpineol (3.6%), neral (8.1%), geraniol (14.5%), geranial (9.5%), trans-dimethoxy citral (5.0%) and geranyl acetate (6.3%). Five compounds, namely trans-linalool oxide, trans-linalool oxide acetate, ( Z)-dimethoxycitral, ( E)-dimethoxy citral and epi-zingiberenol are reported for the first time in oil of ginger.
