ABSTRACT 2011. Antioxidant and antileukemic properties of selected fenugreek (Trigonella foenum-graecum L.) genotypes grown in western Canada. Can. J. Plant Sci. 91: 99Á105. Fenugreek (Trigonella foenum-graecum L.) is an annual forage legume known to have a number of important medicinal properties such as being anti-diabetic and hyperchloesterolaemic among others. In this study we have investigated the anti-oxidant and antileukemic properties of five fenugreek genotypes (L3068, L3375, Tristar, PI143504 and Amber) grown in western Canada for their potential use as nutraceuticals. Our preliminary experiments conducted in two different laboratories showed that the seeds grown in western Canada have anti-oxidant and antileukemic properties and the genotypes differ in the two traits studied. All the genotypes were found to be good scavengers for hydroxyl and free radicals. Among all the varieties, L3068 showed a higher EC 50 value i.e., lower inhibitory activity for lipid peroxidation than the standard catechin. Although all five extracts showed significant antioxidant activity, the crude extract of Tristar was the most effective. Out of the five cultivars of fenugreek, Amber and L3375 showed a robust antileukemic activity followed by Tristar. Hence we conclude that Tristar has the best potential among all the genotypes tested to be used as a future nutraceutical crop when grown in western Canada.

    ABSTRACT: Trigonella foenum in graecum (Fenugreek) is a traditional herbal plant used to treat disorders like diabetes, high cholesterol, wounds, inflammation, gastrointestinal ailments, and it is believed to have anti-tumor properties, although the mechanisms for the activity remain to be elucidated. In this study, we prepared a methanol extract from Fenugreek whole plants and investigated the mechanism involved in its growth-inhibitory effect on MCF- 7 human breast cancer cells. Apoptosis of MCF-7 cells was evidenced by investigating trypan blue exclusion, TUNEL and Caspase 3, 8, 9, p53, FADD, Bax and Bak by real-time PCR assays inducing activities, in the presence of FME at 65 μg/mL for 24 and 48 hours. FME induced apoptosis was mediated by the death receptor pathway as demonstrated by the increased level of Fas receptor expression after FME treatment. However, such change was found to be absent in Caspase 3, 8, 9, p53, FADD, Bax and Bak, which was confirmed by a time-dependent and dose-dependent manner. In summary, these data demonstrate that at least 90% of FME induced apoptosis in breast cell is mediated by Fas receptor-independently of either FADD, Caspase 8 or 3, as well as p53 interdependently.

    ABSTRACT: Fenugreek (Trigonella foenum-graecum L.) is an annual, bloat-free, forage legume and is currently grown in the continents of west, south and south-east Asia, North Africa, Mediterranean Europe, Australia, and North America. In addition to its use as a forage crop, it is most widely known all over the world as an aromatic and spice crop with a number of medicinal properties. The plant is an important source of essential phytochemicals such as steroidal sapogenins, galacatomannans, 4-hydroxyisoleucine, antioxidants to name only a few. Fenugreek has been extensively studied for its role in treatment of diabetes and hypercholesterolaemia, both in traditional medicinal practices as well as in modern drug based medicinal applications. However, this species is not much known or widely cultivated in Latin America, although suitable arid to semiarid, rainfed agro-climatic conditions are available. Furthermore, has remained unknown or less known to farmers, producers, breeders and crop and forage researchers in Latin America. This is the first comprehensive review to introduce fenugreek as potential forage crop for Latin America and has been suggested how it could be made into a regular crop under agro-pastoral systems. The following review highlights the crop, its botanical status and in depth discussion of the crop agronomy, breeding, genetics, medicinal properties with particular emphasis on its seeds in the control of Diabetes Mellitus.
