Goal: The aim is to have study of phytochemical Cacalia hastata leaf. Materials and Methods: We performed the research taking material assistance of pharmacognozy laboratories in Monos university from 2012-2013. The quantitative and qualitative analyses of plant bioactive compounds were evaluated by Russian XI Pharmacopeia and the method according to Mongolian National Standard. Result of the study was developed by SPSS 16 and End notе programme. Result: The quantitative and qualitative analyses of plant bioactive compounds of Dianthus superbus upper part of the land were evaluated by Russian XI Pharmacopeia and the method according to Mongolian National Standard and alkaloid, tannin, coumarone, flavonoid and natural active substances were found. Conclution: It was carried out phytochemical investigation of the Cacalia hastata using spectrophotometer as a result we determined that it contains 8.53 % of sum flavonoid, 12.3 % coumarone. Amount of biological active compound-tannins was 15 %, alkaloid 0.0074 %.
