Collection and Partial Characterization of Volatile Selenium Compounds from Medicago Sativa L.

Abstract

Tops and roots of Medicago 8ativa plants raised in culture solution to which 75Se·labelled selenite or selenate had been added were shown to release 0·5-3·0% of their total selenium in volatile form when dried at 70°C for 48 hr. The volatile selenium compounds were collected on activated charcoal.
