The authors examined 150 samples of almost 100 plant species, mainly Gramineae, Fabaceae and weeds. 18 of the tested plants contained demonstrable, sometimes considerable amounts of saponins. A number of internal and external factors have an effect on the quantity of saponins in the plants. The conclusions of changes of the quantity of haemolytic saponins in the plants are as follows: 1. In the ontogeny of alfalfa the fore-summer (1st) cut contained the greatest quantity of saponin in both leaves and stalk of plants. 2. The ration between the saponin content of leaves and stalk of the aftermaths is usually 2:1 and at blossoming the proportion in the leaves increases considerably. During ontogenesis of the plant the quantity of active substance in the leaves increases steadily. 3. The haemolytic saponin content of the same species (e.g. alfalfa) but harvested from different soils showed considerable differences.
