ABSTRACT The tubers of Lepidium meyenii contain the benzylated derivative of 1,2-dihydro-N-hydroxypyridine, named macaridine, together with the benzylated alkamides (macamides), N-benzyl-5-oxo-6E,8E-octadecadienamide and N-benzylhexadecanamide, as well as the acyclic keto acid, 5-oxo-6E,8E-octadecadienoic acid. The structure elucidation of the isolated compounds was based primarily on 1D and 2D NMR spectroscopic analyses, including 1H-1H COSY, 1H-13C HMQC, 1H-13C HMBC and 1H-1H NOESY experiments, as well as from 1H-15N NMR HMBC correlations for macaridine and N-benzylhexadecanamide.

    ABSTRACT: From the roots of Lepidium meyenii Walpers (Brassicaceae), two flavonolignans, tricin 4'-O-[threo-β-guaiacyl-(7''-O-methyl)-glyceryl] ether (1) and tricin 4'-O-(erythro-β-guaiacyl-glyceryl) ether (2), along with eleven other known compounds, tricin (3), pinoresinol (4), 4-hydroxycinnamic acid (5), guanosine (6), glucotropaeolin (7), desulfoglucotropaeolin (8), 3-hydroxybenzylisothiocyanate (9), malic acid benzoate (10), 5-(hydroxymethyl)-2-furfural (11), D-phenylalanine (12), and vanillic acid 4-O-β-D-glucoside (13), have been isolated and identified. Structures were elucidated on the basis of NMR and MS data. Some isolates and previous isolated lepidiline B (13) were tested for cytotoxicity in a small panel of human cancer cell lines (Hep G2, COLO 205, and HL-60) and anti-inflammatory activities in LPS-treated RAW264.7 macrophage. Among them, compound 1 and 14 were modestly active for inhibiting nitrite production in macrophage. Compounds 1, 14 and 3 were demonstrated to be selectively active against HL-60 cells with an IC50 of 40.4, 52.0, and 52.1 M, respectively.

    ABSTRACT: Maca, Lepidium meyenii Walpers (Brassicaceae), is an annual herbaceous plant native to the high plateaus of the Peruvian central Andes. Its underground storage hypocotyls have been a traditional medicinal agent and dietary staple since pre-Columbian times. Reported properties include energizing and fertility-enhancing effects. Published reports have focused on the benzylalkamides (macamides) present in dry hypocotyls as one of the main bioactive components. Macamides are secondary amides formed by benzylamine and a fatty acid moiety, with varying hydrocarbon chain lengths and degree of unsaturation. Although it has been assumed that they are usually present in fresh undamaged tissues, analyses show them to be essentially absent from them. However, hypocotyls dried by traditional Andean postharvest practices or industrial oven drying contain up to 800μgg(-1) dry wt (2.3μmolg(-1) dry wt) of macamides. In this study, the generation of macamides and their putative precursors were studied during nine-week traditional drying trials at 4200m altitude and in ovens under laboratory conditions. Freeze-thaw cycles in the open field during drying result in tissue maceration and release of free fatty acids from storage and membrane lipids up to levels of 1200μgg(-1) dry wt (4.3μmolg(-1) dry wt). Endogenous metabolism of the isothiocyanates generated from glucosinolate hydrolysis during drying results in maximal benzylamine values of 4300μgg(-1) dry wt (40.2μmolg(-1) dry wt). Pearson correlation coefficients of the accumulation profiles of benzylamine and free fatty acid to that of macamides showed good values of 0.898 and 0.934, respectively, suggesting that both provide sufficient substrate for amide synthesis during the drying process.

    ABSTRACT: The pentane extract of the Peruvian plant Lepidium meyenii (Maca) has been shown to possess neuroprotective activity in vitro (in crayfish neurons) and in vivo (in rats subjected to focal ischemic stroke). These results suggested a potential application of the lipophilic compounds from Maca as neuroprotectants. The current study was designed to examine the neuroprotectant activity in rat neuroblastoma cells and the involvement of the endocannabinoid system in the mechanism of action of the Maca pentane extract. Rat neuroblastoma cells were pretreated with vehicle or O-2050 (a high affinity cannabinoid CB1 receptor silent antagonist) and exposed one hour later to either: Maca pentane extract or anandamide (an endogenous cannabinoid). After 1 hour incubation, cells were exposed to oxidative damage with H2O2. Cell viability was determined 24 hours later by the trypan blue exclusion cell count method and the spectrophotometric dimethylthiazolylcarboxymethoxyphenyl-sulfophenyl-tetrazolium (MTS) method. The neuroprotectant activity of the pentane extract was confirmed. Compound O-2050 alone produced neurotoxic effects, and significantly (p < 0.05) antagonized the neuroprotectant activity of the pentane extract when used in combination. The pentane extract was tested in an in vitro model using human recombinant fatty acid amide hydrolase (FAAH), the enzyme responsible for endocannabinoid degradation. The Maca pentane extract demonstrated a significant concentration-dependent FAAH inhibitory activity (p < 0.05) at concentrations between 0.1 to 30 μg/mL. These results suggest a potential application of Maca or its constituents as FAAH inhibitors. Maca lipophilic constituents may influence neurotransmission in the central nervous system and may act through the endocannabinoid system to protect neurons against excitotoxic damage.
