Fraxinus omus

What exactly was manna Its sweetness, and the fact that it was available in an arid land, suggests it was rich in trehalose. This being so, then there are several possible sources. It may have been the cocoon of a parasitic beetle, called trehala mana, which contains around 25% trehalose. A possible contender is the solidified juice of the flowering ash, also known as the manna ash (Fraxinus omus) which oozes from its bark and solidifies. This too is collected and sold commercially. Another suggestion is that manna is the lichen Lecano-ra which curls up into balls when there is a drought. These can be blown by the wind and are sometimes collected and used to make...

Since the complement system is highly involved in an inflammatory response [54,55] many substances exhibiting anticomplementary activity have proved to be effective antiinflammatory agents [56]. In this connection we studied and compared the effects of the ethanolic extract of Fraxinus omus bark and its main component esculin (1) on some in vitro and in vivo reactions related to acute inflammatory processes [57]. Quantitative RP-HPLC analysis of the total extract used in this study showed the following hydroxycoumarin composition esculin 40.0%, esculetin 2.4%, fraxin 7.8% and ffaxetin 0.4% [14]. 

The Selva di Callignano is a protected floristic area of about 8 ha located a few kilometres from Ancona (Central Italy). The dominant plants are Quercus cerris L. and Quercus pubescens Willd, which are almost coeval and around 70 years old. In the wood studied, there is an area of about 3 ha covered by vegetation made up of Quercus cerris L., Fraxinus omus L., Sorbus torminalis (L.) Crantz, Ostrya carpinifolia Scop., and Acer campestre L., with shrub and...
