The aim of the research was to identify characters which determine the yield and the content of silymarin in the fruits (achenes) of Silybum marianum as well as to show the range of their variation. The research was performed based on field experiments conducted at the Mochełek Research Station (53°13’ N; 17°51’ E) over 2003-2005. Fruit yield and the content of silymarin were affected mainly by weather conditions, the forecrop and the sowing time. The coefficient of variance for fruit yields was 37.3%, and the content of silymarin – 12.7%. Plant height prior to harvest, number of fruits per anthodium on lateral and main shoots, thousand fruit weight, number of anthodiums with pappus and number of all the anthodiums per plant were significantly correlated with fruit yield. The content of silymarin was positively correlated with the number of plants per m² prior to harvest, plant height prior to harvest and fruit yield, and negatively correlated with the content of total N in the reserve material of fruits. The content of flavonolignans which make up the silymarin appeared relatively constant and only silydianin changes slightly more than the content of silychristin and isosilybin.

The objective of this study was to evaluate the content of phenolic glycosides in willow bark. Salix daphnoides Vill., S. purpurea L. and S. alba L. were taken from their natural habitats. Afterwards, the ecotypes with the highest phenolic glycosides content were used in field cultivation. There was substantial evidence to indicate that violet willow contained the highest amount of phenolic glycosides. Taking into account limited number of its stands violet willow can be regarded as a good source of quality stuff while cultivating. The ecotypes of Salix daphnoides and S. purpurea were selected for the study to be used in field cultivation. As a result the concentration of salicylates was much higher than in their natural habitats.

Celem pracy było określenie wpływu długoterminowego przechowywania, a także technologii utrwalania grasicy (zamrażanie oraz składowanie w temperaturze -12 i -30°C i liofilizacja) na jej przydatność jako surowca farmaceutycznego. Oznaczano zmiany ilościowe w obrębie białek rozpuszczalnych i azotu aminowego oraz pH. Stwierdzono, że największe zmiany ilościowe białek rozpuszczalnych miały miejsce w liofilizatach grasicy, a azotu aminowego w gruczole przechowywanym w -12°C. Natomiast zmiany pH we wszystkich badanych wariantach były minimalne. Największą stabilnością charakteryzował się surowiec składowany w temperaturze -30°C.
