Abstract
Diplomsko delo govori o maci (Lepidium meyenii Walp.), rastlini iz družine križnic (Brassicaceae), ki izvira iz centralnih Andov Peruja. Predstavljen je način tradicionalnega pridelovanja in sušenja mace. Predstavljene so ekološke razmere, v katerih raste ta rastlina. Gre za ekstremne rastne razmere na visokih planotah Andov, ki zahtevajo posebno prilagojenost rastline. Poznanih je več fenotipov mace, ki se med seboj razlikujejo predvsem po barvi, med katerimi so najbolj razširjene rumena, rdeča in črna maca. Ugotavljajo, da se razlikujejo tudi po učinkih. Uporablja se gomolj mace. Je tržno zanimiv prehranski dodatek in ima potencialno vrednost v farmaciji, medicini in kozmetični industriji. Gomolji mace vsebujejo različne prehransko pomembne snovi, največ ogljikovih hidratov, predvsem škroba, beljakovine, minerale, esencialne aminokisline in maščobne kisline. Poleg tega vsebuje tudi različne sekundarne metabolite kot so alkaloidi in glukozinolati. Nekatere od teh snovi so specifične samo za maco. Med njimi so najpomembnejši macaeni in macamidi. V delu so predstavljeni različni za človekovo zdravje pomembni učinki bioaktivnih sestavin mace. Mehanizmi in delovanja teh snovi so še slabo raziskani. Delo predstavlja tudi nekatere ugotovitve s področja strupenosti. Predstavljeni so načini uporabe in tržna zanimivost produktov iz mace. V diplomskem delu ugotavljamo, da so potrebne dodatne študije, ki bi lahko jasneje odgovorile na vprašanja o učinkovanju in strupenosti mace.

Title:Benefits and potential toxicity of maca (Lepidium meyenii Walp.)
Abstract:
The thesis discusses the maca (Lepidium meyenii) from Cruciferae family (Brassicaceae) originate in Central Andes of Peru. We discuss traditional agronomy and drying of maca. We present the extreme growing conditions on the highlands of Andes that force the plant to be perfectly assimilated. There are different phenotypes of maca which differentiate by their effects. The most common are yellow, red and black maca. The tuber of maca is economically interesting food supplement and has the potential values in pharmacy, medicine and cosmetic industry. Tuber contains different nutritionally important ingredients e. g. starch, minerals, essential amino acids and fatty acids. Furthermore it contains different secondary metabolites e. g. alkaloids and glucosinolates beside this it contains its own unique substances, the most important are macaenes and macamides. In this thesis are presented potential pharmacological effects of maca. The mechanisms and function of different maca substances hasn’t been studied enough yet. We present some statements from toxicological point of view. In the thesis we present uses and economy of maca products. We recognize the lack of studies which could clearly answer the questions about maca effects.

Keywords:maca, Lepidium meyenii, active ingredients, uses, agronomy, toxicology, ethnobotany
