摘 要:The ~3H-labelled belladonna alkaloids obtained by catalysed exchange method with microwave excitation was investigated. The specific activities of the labelled products Were 16—32 TBq/mol. More than 90% labelled positions of these ~3H-tracers were on phenyl rings. The radiochemical purity and chemical purity of crude products were both in 75—80%.The ~3H-labelled belladonna alkaloids obtained by catalysed exchange method with microwave excitation was investigated.
