Chemical Composition and Its Relationship to In vitro Gas Production of Several Tannin Containing Trees and Shrub Leaves

Abstract

Leaves from a shrub and five trees; Glycrrhiza glabra L, Arbutus andrachne, Carpinus betilus, Juniperus communis, Quercus libari L and Pistica lentiscus, were harvested in dry period (August, September and October) in 2003 from the city of Kahramanmaras, in southern Turkey. The area is located at an altitude of 630 m above sea level. The mean annual rainfall and temperature were 857.5 mm and 16.2C respectively. Leaves were hand harvested from at least 10 different trees, then pooled and oven dried at 60C for 48 h
