Extraction of pharmaceutically active compositions from a mixture of numerous ingredients, in particular from comminuted plants, such as Tanacetum parthenium, succeeds with a high yield and a surprisingly improved stability of the active substances when the extraction is carried out with a gas, preferably CO.sub.2, in the supercritical state.

Pharmaceutically active composition extracted from tanacetum parthenium,

A glycoprotein with a molecular weight of 38 kD, isolated from the grain of Avena sativa, exhibits surprising pharmacological properties, including immunomodulating activity. The glycoprotein can be used to treat viral and bacterial infections, and can also be used to counter susceptibility to infection arising from a genetic or temporary immunodeficiency. A process for isolating the glycoprotein from Avena sativa is disclosed.
