Leaf Oil of Psidium guajava L. from Cuba

Abstract The chemical composition of the leaf oil of Psidium guajava L. was studied by GC/MS. Fifty-seven components were identified, of which β-caryophyllene (21.6%), (E)-nerolidol (19.2%) and selin-11-en-4α-ol (13.4%) were the major ones.

Essential Oils of Piper peltata (L.) Miq. and Piper aduncum L. from Cuba

Abstract The chemical composition of the essential oils obtained from the leaves of Piper peltata (L.) Miq. and P. aduncum L. from Cuba were examined by combined GC/MS. The oil obtained from P. peltatum was characterized by the presence of caryophyllene oxide (22.9%), spathulenol (9.0%), trans-calamenene (5.4%) and α-copaene (5.2%) as major constituents, while that of P. aduncum contained dillapiole (82.2%) as the major component.

Essential Oil of Chamomile Chamomilla recutita (L.) Rausch. from Iran

Abstract The chemical composition of the essential oil of chamomile Chamomilla recutita (L.) Rausch. was studied by GC/MS. Eighty compounds were identified, of which α-bisabolol oxide A (43.8%), α-bisabolone oxide A (13.6%) and β-bisabolene (19.6%) were the major ones.

Essential Oil from Buds and Leaves of Clove (Syzygium aromaticum (L.) Merr. et Perry) Grown in Cuba

Abstract The chemical composition of bud and leaf oils of Syzygium aromaticum (L.) Merr. et Perry was studied by GC/MS. Thirty-six and 31 volatile compounds have been identified in the bud and leaf oils, respectively. The major components of the bud oil were eugenol (69.8%), β-caryophyllene (13.0%) and eugenyl acetate (16.1%), whereas the leaf oil contained only eugenol (78.1%) and β-caryophyllene (20.5%) as main constituents.

Essential Oil of Chenopodium ambrosioides L. from Cuba

Abstract The chemical composition of the essential oil obtained from aerial parts of Chenopodium amhrosioides from Cuba was examined by combined GC/M S. The oil was characterized by the presence of α-terpinyl acetate (73.9 %) and p-cymene (4.3 %).

Volatile Components of Soursop (Annona muricata L.)

Abstract Volatile components of soursop were isolated by simultaneous steam distillation/solvent extraction and GC/MS analysis. Forty-one compounds were identified. The major volatiles were methyl 3-phenyl-2-propenoate, hexade-canoic acid, methyl (E)-2-hexenoate and methyl 2-hydroxy-4-methyl valerate.

Volatile Components of Tamarind (Tamarindus indica L.) Grown in Cuba

Abstract Volatile components of tamarind fruits grown in Cuba were isolated by simultaneous steam distillation/solvent extraction. The fruit pulp had approximately 3 mg/kg of total volatile compounds. Eighty-one constituents were identified, from which 2-phenylacetaldehyde, 2-furfural and hexadecanoic acid were the major compounds.

Chemical Composition of the Essential Oil of Lantana camara L. from Cuba

Abstract The essential oil obtained from leaves of Lantana camara L. from Cuba was analyzed by GC-FID and GC/MS. The oil was characterized by the high percentage of sesquiterpenes. The major components were (E)-nerolidol (43.4%), δ-cadinene (7.6%), α-humulene (4.9%) and β-caryophyllene (4.8%).

Volatile Components of Avocado (Persea americana Mill.) cv. Moro Grown in Cuba

Abstract Volatile components of avocado fruits cv. Moro were isolated by simultaneous steam distillation/solvent extraction. This cultivar had approximately 9.6 mg/kg of total volatile compounds. Major constituents were (Z)-nerolidol, (E,E)-2,4-decadienal, (E,E)-α-farnesene, β-caryophyllene, caryophyllene oxide and α-copaene.

Leaf Oils of Psidium parvifolium Griseb. and Psidium cattleianum Sabine from Cuba

Abstract The chemical composition of the leaf oils of Psidium parvifolium Griseb. and Psidium cattleianum Sabine were studied by GC and GC/MS. Twenty volatile compounds were identified in P. parvifolium, of which viridiflorol (31.9%) was the major one. Eighteen compounds were identified in P. cattleianum, of which epi-α-muurolol (21.9%), α-cadinol (20.0%), epi-α-cadinol (16.7%) and caryophyllene oxide (13.6%) were major.
