| abstract |
The invention relates to a method for removing undesirable toxic alkaloids, including the precursors and derivative products of said compounds, from plants or vegetable preparations. Said method is characterized in that: in a first step the plant or vegetable preparation containing the above undesirable compounds is brought into contact or mixed with a lipophilic phase which is such that the undesirable compounds to be removed dissolve in or are absorbed by said lipophilic phase and concentrate therein quantitatively or substantially quantitatively; in a second step the lipophilic phase, which now contains the undesirable compounds, is separated from the plant or vegetable preparation concerned; and in a third step the plant or vegetable preparation purified in this manner is recovered. |
