The current study was done on 54 samples of
mcdicinal plants mostly used in public medicine as a
treatment of kidney affections , common cold , cough and
constipation these plants are Cymbopogon proximus
,Imbrosia maritime, Artmesia, Telio Ginger,
Cinnamomum Nigella saliva and Cassia Senna and were
collected randomly from 3 different localities in Egypt
(Moshtohor ,Tukh & C airo),. The incidence and
concentrations of` of mycotoxins (Ochratoxin A and
Aflatoxin B I ) were determined in these plants Also , some
mycotoxins producing fungi were isolated from these plants
Basidiobatrys Sp. A. flavous , A. niger , A.parasiticus ,
A.Ochracious and Fusurium sp. ) . All samples were
subjected to gamma radiation at 5 kGy to investigate the
possibility of controllling mycotoxins and fungi in medicinal
plants. Our results indicated that gamma radiation
destroyed the majority of mycotoxins and fungi in gamma
irradiated medicinal plants however , some mycotoxins
and fungi still present in medicinal plants even after
exposure to gamma radiation at the recommended dose
We concluded that gamma radiation is a useful control
method for mycotoxins and fungi in medicinal plants but
other control measures either in preharvest, harvest or
storage period of these plants should go hand in hand.
