Although cholesterol, the principal animal sterol, has been isolated from many higher plant species, in most cases it was reported to occur only in trace amounts1,2 For this reason, cholesterol has generally been considered to be of relatively little significance in higher plants. In the course of our work on the sterol profiles of different plant tissues during floral development, we have identified very high levels of cholesterol in the shoot-apices of various plants. Sterol profiles of two monocot plants, Hordeum vulgare and Lolium temulentum, and one dicot plant, Xanthium strumarium, were studied. Our results suggest a specific association of cholesterol with meristematic and/or reproductive tissues.
