Development of ways and possibilities of adaptation of plants when introducing them in the forest-steppe zone of West Siberia is currently important and connected with biochemical processes, in particular, accumulation of storage substances in geophytes. Among them there are representatives of rhizomical plants of the genera Hemerocallis L. important in ornamental floriculture of our region.

The aim of the work - is comparative study of the component composition of storage substances in above the ground and organs Hemerocallis minor in the forest-steppe zone of West Siberia.

A quantitative composition of storage substances Hemerocallis was defined. Dynamics of accumulation of sugars, starch, saponins, ascorbic acid, pectins, protopectins, catechins and tanning matters in leafs and zhizomes in the forest-steppe zone of West Siberia was established for the first time. Pectins were determined by the carbazole method, sugars – by the A.S. Shvetsov and E. Kh. Lukyanenko method, catechins – by the spectrophotometric method, starch – by the acid hydrolysis method, saponins – by the weight method and tanning matters and acidity – by the titrometric method.

On the basis of the data obtained it was concluded:

1. Individual and common conformity of the accumulation and expenditure emergency substances in leafs and rhizomes were established. Eight common components of sugars, starch, saponins, ascorbic acid, pectins, protopectins, catechins and tanning matters were defined.

2. Content of sugars in above the ground organs by 2 times higher, than underground organs, accorbic acid by 8-10  times higher, accordingly.

3. In underground organs of saponins by 2-3 times higher, than above the ground organs.
