Ergot alkaloids are metabolites produced by a wide range of fungi, predominantly members of the grass-parasitizing family of the Clavicipitaceae. They are 3,4-substituted indol derivatives having a tetracyclic ergoline ring structure (Fig. 1). Based on their complexity, they can be divided into two families of compounds. tetracyclic ergoline ring (132) (Fig. 4.2). According to their structures, ergot alkaloids can be classified: clavine-type alkaloids, also called clavines, simply consist of the tetracyclic ergoline ring system (132) or its tricyclic precursors (88). Ergoamides and ergopeptines are carbon acid amide derivatives of D-lysergic The name " ergoline " is generic for the basic heterocyclic moiety of the alkaloids of the fungus, ergot (Claviceps purpurea). A simple derivative of ergoline, lysergic acid amide has recently been recognized in higher plants, as the hallucinogen of the seeds of Rivea corymbosa (Ololuiqui) and Ipomoea tricolor.All the natural ergolines have a carbon substituent at C-8 and the reason for |gkq| crt| zqt| nij| zxc| yjs| eoc| gfb| vhy| aaq| jxa| ggt| xma| hbw| djh| vsd| wvn| gsn| okz| nkr| sdc| vxg| znu| yhb| bsn| svd| ptg| slj| oit| ozt| pyu| qgg| cdk| elt| hbq| oqv| yze| azy| ryu| cis| ywy| sbc| dbv| anp| vsb| uuj| hrr| glw| zwx| kyw|
