摘要：

Leaflets of 78 type herbarium specimens including 78: species of Astragalus species from Iran were analyzed for toxic aliphatic nitro compounds. The catabolites of nitro compounds, 3-nitropropanol and 3-nitropropionic acid are especially toxic to cattle and sheep. Nitro compounds were detected in six species of Astragalus and all the nitro-bearing species were herbaceous. The occurrence of nitro toxins in four species of Astragalus is reported for the first time. Nitro-toxins are more common among the simple haired Astragalus species. (C) 2002 Elsevier Science Ltd.
