          Antioxidant, antimutagenic, and antidiabetic activities of edible leaves from Cnidoscolus chayamansa Mc. Vaugh.

          The methanolic extract of Cnidoscolus chayamansa leaves from Mexico was screened for antioxidant and antimutagenic properties by the DPPH, ABTS, iron chelating, and Kado microsuspension assays, respectively. The hypoglycemic effect was also studied. Total phenolic and flavonoid contents as well as HPLC identification and quantification of protocatechuic acid and rutin were also carried out. The C. chayamansa leaves extract contained 71.3 +/- 1.7 mg gallic acid equivalent/g extract and 42.6 +/- 3.7 mg (+)-catechin equivalent/g extract of total phenols and flavonoids, respectively. Concentrations of 0.242 +/- 0.001 mg/g and 2.00 +/- 0.097 mg/g were found for protocatechuic acid and rutine, respectively. The extract was capable of scavenging DPPH and ABTS(+) radicals in a concentration dependent manner. The extract was not toxic to TA100 and TA98 strains at the concentrations tested; moreover, the extract at a concentration of 1000 microg inhibited 24% and 39% the mutagenicity induced by 4-nitro-O-phenylenediamine and sodium azide, respectively. An acute hypoglycemic effect in diabetic rats was observed.

            Compuestos polifenólicos y capacidad antioxidante de especias típicas consumidas en México

            Las especias son plantas aromáticas que han sido utilizadas ampliamente en México para preservar o sazonar diversos alimentos, aunque también se han usado como remedios herbolarios para curar algunas enfermedades. Las propiedades culinarias y medicinales de las especias han sido atribuidas a diversos componentes, entre ellos los fitoquímicos. De estos últimos, los compuestos polifenólicos han sido ampliamente estudiados por el efecto contra enfermedades crónico degenerativas que se les atribuye, posiblemente por su capacidad antioxidante. El estudio de la capacidad antioxidante de las especias mexicanas abre puertas a nuevas investigaciones sobre los posibles beneficios de estas especias en la salud humana. El presente trabajo presenta las principales investigaciones sobre los potenciales efectos beneficiosos de las especias tradicionales mexicanas en la salud humana.
