摘要:

Essential oil from steam distilled whole plants of basil,Ocimum basilicumL., cv. Large Green, harvested with different flower sizes was compared with oil produced from basil flowers only. Higher yields were obtained when distilling basil with long flower spikes (12 to 20 cm) rather than with shorter flower spikes. Distilling the whole plant gave an oil with a higher percentage of methyl chavicol whereas the flower spikes produced an oil richer in linalool.

摘要:

Mild and moderate plant water stress increased sweet basil leaf essential oil content and altered oil composition. After 21 d of plant water deficit, the oil content of leaves increased from 3.1 to 6.2 μl.g1 leaf dry wt. as xylem water potential (ψ) decreased from −0.30 to −1.12 MPa. Significant decreases in leaf dry weight and stem dry weight were observed as plant water deficit increased. Only leaf area from plants subjected to a mild water deficit (-0.68 MPa) was not significantly reduced compared to the control, non-stressed plants.

摘要:

An essential oil ofConyza pinnataKuntz which was produced from plant material collected in Zimbabwe, was examined by a combination of peak enrichment and GC/MS. Eleven components were fully characterized from which (E)-β-ocimene (~40%) and cuminyl alcohol (~25%) were the major components.

摘要:

The essential oil ofLepidophyllum quadrangularewas analyzed by a combination of GC/MS. The oil was found to contain 67 constituents of which 37 were identified. The major compounds were α-pinene (17–19%) and β-pinene (11–13%), and a variety of sesquiterpenes such as δ-cadinene (8–10%), γ2-cadinene (1.4–1.7%), γ-cadinene (0.6–0.7%) and α-muurolene (2.0–2.3%).

摘要:

The chemical composition of the fruit essential oil ofLaser trilobumgrowing wild in Turkey was determined by capillary GC and GC/MS. Among the twenty two components identified, limonene (60.70%) and perillaldehyde (32.30%) were found to be the major constituents.

摘要:

The essential oil of the seeds ofAmomum tsao-koCrevost et Lemarie of Vietnamese origin has been analyzed by a combination of GC and GC/MS. Twenty-one components have been identified, of which the major ones were found to be 1,8-cineole (30.6%), 2-decenal (17.3%), geranial (10.6%) and neral (7.0%).

摘要:

The foliar oils ofPimenta jamaicensis(Britton & Harris) Proctor of Jamaica, which were analyzed by GC/MS, were found to possess oils which were dominated by either eugenol (61.79%) and limonene (10.33%) with a lesser amount of β-caryophyllene (5.77%), or 1,8-cineole (43.94–49.43%), α-terpineol (0.34–18.02%) and p-cymene (2.25–10.25%) with a lesser amount of 4-terpineol (6.37–7.17%).
