Hydraulic architecture of leaf venation in Laurus nobilis L
Veins are the main irrigation system of the leaf lamina and an understanding of the hydraulic architecture of the vein networks is essential for understanding leaf function. However, determination of leaf hydraulic parameters is challenging, because for most leaves the vein system is reticulate, contains a hierarchy of different vein sizes, and consists of leaky conduits. We present a new appro...
متن کاملIn vitro and in vivo effects of Laurus nobilis L. leaf extracts.
The in vitro and in vivo antioxidant activities of different extracts of laurel leaves were studied. Free radical scavenging capacity (RSC) was evaluated measuring the scavenging activity on the DPPH, NO, O(2)(.-) and OH radicals. The effects on lipid peroxidation (LP) were also evaluated. Experimental results indicate that ethyl acetate extract of leaves has exhibited the largest RSC capacity ...
متن کاملDecline of leaf hydraulic conductance with dehydration: relationship to leaf size and venation architecture.
Across plant species, leaves vary enormously in their size and their venation architecture, of which one major function is to replace water lost to transpiration. The leaf hydraulic conductance (K(leaf)) represents the capacity of the transport system to deliver water, allowing stomata to remain open for photosynthesis. Previous studies showed that K(leaf) relates to vein density (vein length p...
متن کاملEvaluation of wound healing activity of Allamanda cathartica. L. and Laurus nobilis. L. extracts on rats
BACKGROUND Allamanda cathartica. L. is a perennial shrub used in traditional medicine for treating malaria and jaundice. Laurus nobilis. L. is a tree and has been used for its astringent, healing and diuretic properties. The objective of this study was to investigate the aqueous extracts of Allamanda and Laurus nobilis to evaluate their wound healing activity in rats. METHODS Excision and inc...
متن کاملIsolation and identification of cytotoxic compounds from Bay leaf (Laurus nobilis)
Bay leaf belongs to the family Lauraceae, and it is one of the most popular culinary spices in all Western countries. Bay leaf has been used as herbal medicine and has pharmacological activity which includes anti-bacterial, anti-fungal, anti-diabetes and antiinflammatory effects. The goal of this study was to identify compounds from Bay leaf (Laurus nobilis), which are responsible for inducing ...
