Ecological and biochemical features of genus Trifolium L. plants, growing in South Yakutia (on the example of Neryungri city)

The chemical composition of T. pratense in the conditions of Neryungri is quite poor. Substances have no rather expressed optical activity. Generally there are the compositions of initial stage of flavonoids synthesis - oxycinnamon acids and benzopyrones. As a part of T. hybridium there extracts oxycinnamon acids, flavonoids (5 spots), saponina (5 spots), glycosides, iridoida, derivatives of catechin, poly-and monophenols are defined. From 4 types of a clover, growing in Neryungri and in Neryungrinskiy district the clover creeping which is in the condition of active expansion is most adapted to conditions of South Yakutia. The approximate sequence of types from steadier to less steady in the conditions of Neryungri: T. repens - T. lupinaster - T. hybridium - T. pratense.
