“…Moreover, the alkaloids in maca contained several specific compounds, such as macamides, macaenes, and macaridine that have been regarded as the primary active ingredients of maca since they were first discovered [12,34,35]. The antioxidant activity of maca has also been hypothesized to be the basis of other bioactivities [9,14,17,18]. Thus, these specific alkaloid compounds may effectively contribute to the antioxidant activity of maca.…”

“…Both maca stock and its ethanol extract have demonstrated antioxidant activity. However, a number of researchers have studied a variety of maca bioactivities, including improved growth rate [14], reduced menopause syndrome [9], antiproliferative functions [15], increased swimming endurance capacity [16], and enhanced sperm quantity and quality [17,18]. These bioactivities have 2 Journal of Food Quality been hypothesized as a result of antioxidation properties of maca, which are based on the capacity of scavenging free radicals, inhibition of lipid peroxidation, improved activity of antioxidant enzymes, and attenuation of oxidative stress.…”

The antioxidant capacity of maca has been considered to be the basis for other bioactivities, and revealing the active antioxidant compounds would help to elucidate a variety of bioactive compounds. In this study, the correlation between the antioxidant activity of maca and secondary metabolites, including ferric reducing antioxidant potential (FRAP), hydroxyl radical scavenging ability (HRSA), lipid peroxidation inhibition ability (LPIA), total phenolic contents (TPCs), total alkaloid contents (TACs), and total sterol contents (TSCs), was investigated by measuring. Chloroform was selected to be an efficient extraction solvent for antioxidant compounds in maca by polarity fractions test. The results showed that TPC exhibited significant linear correlations ( < 0.05) to FRAP and LPIA, while TAC had significant linear correlations ( < 0.05) to FRAP, HRSA, and LPIA. These results suggested that alkaloids and phenols were the most important substances for the antioxidation of maca, of which the antioxidant effect of alkaloids seemed to be higher than that of phenols.

RESUMENLa maca (Lepidium meyenii) es una planta que crece sobre los 4000 metros de altitud en los Andes Centrales del Perú, presenta diferentes variedades de acuerdo al color de su hipocótilo. La presente revisión resume los resultados de estudios sobre los efectos de la maca en la función sexual, la espermatogénesis, la función reproductiva femenina, la memoria, la depresión y la ansiedad, como energizante y contra la hiperplasia benigna de próstata, osteoporosis y síndrome metabólico. Se discute también su efecto antienvejecimiento y la seguridad en su consumo. Se han demostrado diferencias en el efecto de las variedades negra, amarilla y roja de maca. La maca negra es la que mejores resultados presenta sobre la espermatogénesis, la memoria y contra la fatiga, mientras que la maca roja es la variedad que mejor revierte la hiperplasia benigna de próstata y la osteoporosis inducida experimentalmente. Además, la maca reduce los niveles de glucosa, y su consumo se relaciona con la reducción de la presión arterial y un mejor puntaje de salud. Estudios experimentales han demostrado que el consumo a corto como a largo plazo no muestra toxicidad tanto in vivo como in vitro. A pesar que los estudios experimentales han demostrado que la maca presenta diversos efectos benéficos, son necesarios más estudios clínicos para confirmar estos resultados.

MACA (Lepidium meyenii Walp), A REVIEW OF ITS BIOLOGICAL PROPERTIES ABSTRACTMaca (Lepidium meyenii) is a plant that grows above 4000 altitude meters in Peru's Central Andes; it has different varieties according to the color of the hypocotyl. This review summarizes the results of studies about the effects of maca on sexual function, spermatogenesis, female reproductive function, memory, depression and anxiety, and energy as well as effects on benign prostatic hyperplasia, osteoporosis and metabolic syndrome. Its anti-aging effect is also discussed as well as safety in consumption. Differences have been shown between the effects of the black, yellow and red maca varieties. Black maca shows the best results on spermatogenesis, memory and fatigue, while red maca is the variety that reverses the benign prostatic hyperplasia and experimentally induced osteoporosis. In addition, maca reduces the glucose levels, and its consumption is related to the lowering of blood pressure and an improved health score. Experimental studies have proven that short and long term consumption don't show in vivo and in vitro toxicity. Although experimental studies have shown that maca has diverse beneficial effects, more clinical studies are needed to confirm these results.

“…Briefly, dietary amino acids were provided in free, peptide or protein molecular forms (Table·1). Diets were isonitrogenous and isolipidic and contained either (1) casein-gelatin as the protein source ['casein' diets, with (+) or without (-) inclusion of maca meal; Lee et al, 2004], (2) a mixture of synthetic dipeptides ('dipeptide' diet) or (3) a mixture of synthetic amino acids ('Free AA' diet). The levels of amino acids in the experimental diets (g·100·g -1 ) were calculated from added amounts (Dabrowski et al, 2003) (Kim et al, 1992;Berge and Storebakken, 1996;Yamamoto et al, 2000;Halver, 2002).…”

SUMMARY The premise that a dietary dipeptide approach will improve the understanding of amino acid utilization in the fastest-growing vertebrate, the teleost fish, was tested by examining the muscle free amino acid (FAA) pool and enzyme activities, in concert with growth response, when dietary amino acids were provided in free, dipeptide or protein molecular forms. We present the first evidence in fish that, in response to a synthetic dipeptide diet,muscle FAA varies as a result of both growth rate and amino acid availability of specific peptides. We demonstrate significantly diminished muscle indispensable FAA (3–10-fold) in rainbow trout alevins fed a dipeptide-based diet compared with a protein-based diet. The dipeptide-based diet did not contain proline, resulting in 10–27-fold less muscle free proline and hydroxyproline in alevins. The response of alevins fed FAA-based or peptide-based diets can be indicative of collagen turnover (Hyp/Pro ratio)and showed significant differences between dietary treatments. Pyrroline-5-carboxylate (P5C) reductase activity was detected, suggesting that P5C may ameliorate proline deficiency, but synthesis from glutamate could not maintain free proline levels in muscle. This finding will provide an impetus to test whether proline is conditionally indispensable in young fish, as in mammals and birds. This study shows that amino acids given entirely as dipeptides can sustain fish growth, result in muscle FAA and enzyme responses in line with dietary levels and identify growth-limiting amino acids. The understanding of these factors necessitates a diet formulation that will improve the accuracy of determining amino acid requirements in the early life stages of vertebrates.
