Abstract

Silybin, silydianin, and silychristin, the active constituents of the fruit of the Milk Thistle (Silybum marianum (L.) Gaertn.), in vitro inhibit the IAA–oxidase dependent catabolism of indole–3–acetic acid (IAA). Thence, by control of the endogenous IAA level, to the silymarin group can be attributed a protector function for IAA in plants.
