Among the compounds of primary metabolism that are formed in all living 
organisms on our planet, proteins are essential for growth and development. 
It was interesting to study the proteins of alkaloid-bearing plants, such as 
Dictamnus 
angustifolius, Haplophyllum perforatum, Ruta graveolins,
collected during the 
flowering period in the Republic of Uzbekistan. 
The total protein content in plant samples was determined by the total nitrogen 
content. The colorimetric method using Nessler reagent on a V-5000 Metach 
spectrophotometer [1-2] determined the quantitative protein content in these plant 
organs. The analysis was carried out under laboratory conditions using the accelerated 
method with Nessler reagent. 
The results of the analysis are presented in the table.
