Abstract

Leaflets of 111 specimens including 82 bifurcate haired Astragalus species in 13 sections were taken from the herbarium specimens of Research Institute of Forests and Rangelands (TARI). They were analyzed quantitatively for toxic aliphatic nitro compounds. The catabolites of nitro compounds, 3-nitro-1-propanol and 3-nitropropionic acid, are especially toxic to cattle and sheep. Nitro compounds are also important from chemotaxonomic point of view. These nitro-toxins were detected in 4 of 82 species.

Abstract [Persian]

برگچه‌های 111 نمونه هرباریومی از گون‌های کرک دوشاخه ایران، شامل82 گونه از 13 بخش، به منظور تشخیص ترکیبات ازت‌دار آلیفاتیک سمی مورد بررسی قرار گرفتند. کاتابولیت‌های ترکیبات ازت‌دار، 3-نیترو 1-پروپانول و اسید3- نیتروپروپیونیک، برای احشام سمی هستند. بعلاوه این ترکیبات در طبقه‌بندی گیاهان نیز حائز اهمیت می‌باشند. وجود این نیتروتوکسین‌ها در 4 گونه از 82 گونه مذکور گزارش می‌شود.
