“Yellow moena” (Nectandra longifolia: Lauraceae) is a fragrant leaves-possessing plant commonly used for timber purposes. Nevertheless, so far, there is not available information about its chemical composition. Thus, in the present work is described the components of the essential oil from N. longifolia leaves. The oil was extracted by steam distillation and analyzed by GC/FID  and GC/MS. Twenty eight compounds were therefore identified. The main components were found to be terpinen-4-ol (53.1%), α-terpinene (6.8%), α-phellandrene (4.5%), and β-pinene (3.8%). The chemical composition of essential oil from N. longifolia leaves was consequently in agreement to that of several neotropical Lauraceae plants. In addition, the oil exhibited good antifungal activity against F. oxysporum through dose-dependent mycelial growth inhibition (using amended media and fumigant assays).

The essential oil from Tithonia rotundifolia leaf growing wild in Osun State, Nigeria obtained by hydro-distillation has been characterised for the first time by combined GC and GC-MS analyses. Forty-six components representing 93.8% of the total oil have been fully identified. The oil is characterised largely by sesquiterpene hydrocarbons (78.1%), represented chiefly by germacrene D (33%) and β-caryophyllene (25.8%). The less important classes of components are monoterpene hydrocarbons (5.1%), oxygenated monoterpenes (0.3%), oxygenated sesquiterpenes (3.1%) and non-terpenes (7.2%).

Piper betle L. (Piperaceae) is used in traditional medicinal diseases. Our study was planned to isolate chemical constituents from the leaves of P. betle variety desi and to characterized their structures. Phytochemical investigation of the methanolic extract of the leaves of P. betle variety desi led to isolate n-nonyl benzene (1-phenylnonane, 1), 4′-phenyl butanoxy n-hexanoate (4′-phenyl butanoxy caproate, 2), caffeic acid (3),1′-phenoloxy 5′α-hydroxyltetradecane (4) and 5-prop-2a-enyl-4,4′-(2′′α-arachidyloxy-3′′α-hydroxypropyl)-bispyrocatechol (1′′, 2′′-dihydro-2′′α-arachidyloxy-3′′α-hydroxybischavicol, 5). The structures of these phytoconstituents, isolated from this variety of P. betle for the first time, were established by spectroscopic methods and chemical constituents. The leaf essential oil was characterized by high percentage of farnesol (41.13%), acetyl eugenol (26.40%), valencene (6.34%), α - amorphene (3.43%), γ - cadinene (3.56%), isovanillin (2.27%), eugenol (1.21%), cadina-1,4-dione (1.77%) and α - bisabolene (1.15%).
