Abstract: | Fifteen different plants representing different species, genera and families were used to test the effect of their aqueous extracts on tumor inhibition with a rapid, inexpensive, safe, animal sparing technique, and statistically reliable prescreen for in vivo murine leukemia antitumor activity, which is known as potato disc technique. The inoculum used contains the extract with the bacterium (Agrobacterium tumefaciens) that was known to cause crown gall tumor to different plant species especially dicotyledons and some gymnosperms. After 12 to 21 days of incubation the tumors appeared and were counted, and the maximum inhibition was then calculated. Thirteen species out of fifteen showed a good antitumor effect, and three of them showed a maximum inhibition of 80%. More experiments are necessary to determine the exact mechanism of action. |
