Composition of the Leaf Oil of Eryngium foetidum L. from Cuba

Abstract Water-distilled volatiles from the leaves of Eryngium foetidum L. of Cuban origin were analyzed by a combination of GC and GC/MS. Forty-six components were identified, of which the major ones were found to be 2,4,5-trimethylbenzaldehyde (20.53%), hexadecanoic acid (12.05%) and carotol (9.94%).

Chemical Composition of the Seed Oil of Eryngium foetidum L. from Cuba

Abstract The seed of Eryngium foetidum L. of Cuban origin has been analyzed by GC and GC/MS. Thirty-seven compounds were identified, of which carotol (19–31%), (E)-β-farnesene (9.98%), (E)-anethole (7.43%) and α-pinene (7.69%) were the major constituents.

Volatile Constituents of Guava (Psidium guajava L.) Fruits from Cuba

Abstract Volatile constituents obtained from four cultivars of guava (Psidium guajava L.) fruits by simultaneous steam distillation-solvent extraction, and analyzed by GC/MS. More than 40 compounds were identified in each cultivar, 17 of which have been identified for the first time as volatile constituents of guava. Each cultivar has a typical composition, characterized by a specific ratio between die main components and classes of substances. The major volatiles were either β-caryophyllene, limonene, 3-phenylpropyl acetate, (Z)-3-hexenyl acetate or (E)-cinnamyl acetate.

Chemical composition of the seed oil of Coriandrum sativum L. from Cuba

ABSTRACT The essential oil obtained by hydrodistillation from the dried seeds of Coriandrum sativum L. growing in Cuba was investigated by GC and GC/MS. Thirty-five compounds (96.9%) were identified, of which linalool alone accounted for 54.57% of the oil.

Chemical Composition of the Essential Oil of Artemisia absinthium L. from Cuba

Abstract The essential oil of Artemisia absinthium L. of Cuban origin has been analyzed by GC and GC/MS. More than 40 compounds were identified, of which bornyl acetate (23.02%) was the major constituent.

Chemical Composition of the Essential Oil of Lippia alba (Mill.) N.E. Brown from Cuba

ABSTRACT The essential oil of Lippia alba (Mil.) N. E. Brown of Cuban origin has been analyzed by a combination of column chromatography, GC and GC/MS. Forty-two compounds were identified, of which limonene (6.50%), carvone (28.95%), piperitenone (6.35%) and β-guaiene (11.53%) were the major constituents.

Composition of the Essential Oil from the Leaves and Flowers of Ocimum gratissimum L. Grown in Cuba

ABSTRACT The composition of the essential oil from the leaves and flowers of Ocimum gratissimum L. was analyzed by GC and GC/MS. Although the composition of both oils was similar, the quantity of individual components differed between them. Thymol and p-cymene were the major compounds in both oils.

Composition of the Essential Oil of Artemisia vulgaris L. Herb from Cuba

Abstract The essential oil of dried herb of Artemisia vulgaris L., grown in Cuba, was subjected to GC/MS investigation. Eighteen constituents were identified. The oil consisted mainly of caryophyllene oxide (31.1%).

Composition of the essential oil of Ocimum tenuiflorum L. grown in Cuba

Abstract The volatile oil of the air-dried aerial parts of Ocimum tenuiflorum L. was analyzed by GC and GC/MS. Forty compounds representing 90% of the oil were identified. Eugenol (34.3%), β-elemene (18.0%) and β-caryophyllene (23.1%) were the major constituents.

Chemical Composition of the Essential Oil of Mentha pulegium L. from Cuba

ABSTRACT The essential oil of Mentha pulegium L. of Cuban origin has been analyzed by a combination of GC and GC/MS. Thirty-three compounds were identified, of which neoisomenthol (20.68%) and pulegone (25.14%) were the major constituents.
