Coffee and willow are known as valuable sources of biologically active phytochemicals such as chlorogenic acid, caffeine, and salicin. The aim of the study was to determine the interactions between the active compounds contained in water extracts from coffee and bark of willow (Salix purpurea and Salix myrsinifolia). Raw materials and their mixtures were characterized by multidirectional antiox...

feeding by herbivorous insects. Some of these noxious compounds are both unpalatable and toxic, while others are merely unpalatable or toxic (Bernays and Chapman, 1987; Chapman and Sword, 1994; Glendinning, 1996; Harley and Thorsteinson, 1967). Because many plants concentrate noxious compounds in their most nutritious tissues (McKey, 1979), herbivores would benefit from an ability to adapt to f...

Extremes of climate and hypobaric hypoxia cause poor growth performance in broiler chickens at high altitude the present study investigates effect aqueous extract Salix alba leaves on performance, antioxidant level immune status reared cold desert (3500 m). High liquid chromatography (HPLC) analysis revealed presence salicin caffeic acid. In vitro efficacy evaluation that had a significant cyto...

         Cell cultures of Varthemia persica DC. have been studied to evaluate their abilities in biotransformation of aromatic and aliphatic precursors. V. Persica (Asteraceae) is an aromatic plant growing in Iran. V. persica contain different terpens but its cell culture does not posses these compounds. Callus cultures of V. persica was established ...
