Labiatae pinaceae

ABSTRACT Monoterpenoids are the components of essential oils, which are produced and accumulated, in large amounts by plants from certain families, including Labiatae, Pinaceae, Cupressaceae, Umbelliferae and Rutaceae. They are of special interest because of their industrial applications and on account of their chemical properties and biological activity. Monoterpenic composition can be useful in genetic and chemotaxonomic studies of coniferous species. 

Cinnamomum eamphora (Linne) Nees et Ebermaier, family Lauraceae. The plant grows well in Japan, China, Formosa, India, Burma and Malaysia. Camphor also occurs in certain species of Artemisia, (Compositae) chrysanthemum (compositae), Salvia (Labiatae), Ocimum (Labiatae), Lavander (Labiatae), Pinus (Pinaceae). It is also present in Rosemarinus officinalis (Labiatae), Aristolochia indica (Aristolochi-aceae), Blumea balsamifera (Camphreaceae), Prunella vulgaris Labiatae), Cinnamomum ganduliferum (Lauraceae) etc (38-55) ... 

Juniperus, whereas the corresponding ketone (+)-3-thujanone (F6) is found in the oils of several plants of the families Aster-aceae, Labiatae, and Pinaceae. 

The diterpenoids, which contain 20 carbon atoms, are represented by acyclic, monocyclic, bicyclic, tricyclic, and tetracyclic structures. Over 5,000 naturally occurring diterpenoids, many of which frequently occur in plant families Araliaceae, Aster-aceae, Cistaceae, Cupressaceae, Euphorbiaceae, Leguminosae, Labiatae, and Pinaceae, are known (32). The acyclic diterpenoid... 

Other abietane derivatives with benzenoid ring C are among the active substances in some well-known medicinal herbs. The parent hydrocarbon (-)-8,l 1,13-abieta-triene occurs in the pine tree Pinus pallasiana (Pinaceae). (+)-Camosolic acid and the 20,7p-lactone (-olide) of its hydroxy-derivative referred to as camosol belong to the bitter substances of the oil of sage from Salvia camosa (Labiatae) and related species. (-)-Rosmanol, a 20,6p-lactone, is an antioxidant isolated from the leaves of rosemary Rosmarinus officinalis (Labiatae), which also contain camosol.
