| Abstract: | This paper reports the content analysis of microtoxin 3-NPA and 3-NPOH inA. Adsurgens pall with the method of thin layer chromatography-spectrophotometry. The mi-crotoxin in the plant is less than 10 ppm. There are no toxin in milk and beef. The herbageis a sort of lesstoxin plant and it is a good forage grass. The average rate of recovery is morethan 85%. |
