chemical composition, in situ degradability and in vitro gas production of ephedra plant (ephedra intermedia)

nutritive value of ephedra (ephedra intermedia) was evaluated through determination of chemical compositions, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the samples were harvested during the late spring from rangeland in north of khorasan razavi province. the rate of gas production and degradability characteristics of dry...

Chemical composition of various Ephedra species.

The medicinal significance of Ephedra is based on the sympathomimetic properties of ephedrine (E) alkaloids. Pharmacological effects depend on the phytocomposition of individual Ephedra species. The aim of this study was to measure the total alkaloids content (TAC), total phenolics content (TPC), and total flavonoids content (TFC) and determine their relationship in dry herb of Ephedra major, E...
