“…The authors concluded that this activity could only be attributed to these flavones and not to betalains [ 69 ]. These results disagree with those reported by Rodrigues-Brandão [ 103 ], since the antioxidant activity was related to the betacyanins accumulated by A. tenella growing in vitro. Both increased with the addition of salicylic acid to the culture medium.…”

“…The plant has been also used as diuretic [ 100 , 101 ]. Laboratorial experiments have revealed that A. tenella extracts have immunomodulatory, antioxidant, anti-hyperalgesic, antimicrobial and antiparasitic properties [ 85 , 96 , 101 , 102 , 103 , 104 ]. As reported for A. brasiliana , these activities have been generally attributed to the phenols, particularly flavonoids.…”

Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains with colours that range from yellow to red-violet can de divided into two main subgroups: betaxanthins and betacyanins. These types of pigments are confined into 13 families of the order Caryophyllales and in some genera of higher fungi (Amanita muscaria, Hygrocybe and Hygrophorus). The Amaranthaceae family includes diverse genera in which betalains are present: Alternanthera, Amaranthus, Beta, Chenopodium, Celosia and Gomphrena. The biosynthesis of betalains and their general biological properties were reviwed in the present work. In addition, the types of betalains present in some species of the aforementioned genera, their stability and production, as well as biological attributes, were reviewed.

“…Los resultados obtenidos en esta gramínea de importancia alimenticia y económica, permiten confirmar la participación del AS en la inducción de síntesis de fenoles en las plantas (Dong et al, 2010), a la vez que reafirman su colaboración en la producción de metabolitos secundarios tal como se ha reportado en Alternanthera tenella (Rodrigues-Brandão et al, 2014), Saccharum officinarum y Calendula officinalis L. (Pacheco et al, 2013); además, dan la pauta para proponer su uso como herramienta en la inducción de tolerancia a plagas (García et al, 2003) y enfermedades del grano en maíz (Bakan et al, 2003), y para incrementar el poder antioxidante de este cereal, que se traduce en beneficios potenciales en la salud humana (Adom y Liu, 2002;Liu, 2007).…”

El ácido salicílico (AS) es una molécula multifuncional en las plantas. Se presentan los resultados del contenido total de fenoles solubles (FST) en el grano de maíz (Zea mays L.), cosechado de plantas que fueron asperjadas durante el estado de plántula con 0.1 o 1 μM de ácido salicílico (AS). La cuantificación de los FST se realizó por el método de Folin-Ciocalteu. El tratamiento de 1 μM de AS incrementó significativamente la concentración de FST en el grano en 17 % comparado con el testigo. Los resultados se discuten en relación con la importancia de estos metabolitos secundarios como antioxidantes y compuestos de defensa contra los patógenos.

A pseudo-univariate calibration model was proposed as an alternative method to determine the antioxidants activity (%RSA) in extract from turmeric powder by using the relative intensity from multivariate curve resolution with alternating least squares (MCR-ALS) from near-infrared (NIR) spectra. An extraction was performed by using an ultrasound with probe, ethanol 70% and time 15 minutes. For pseudo-univariate calibration, eight independent samples were prepared from the curcuminoid extracts. NIR spectra were collect from 900 to 1700 nm, and to these samples the percentage of inhibition of DPPH was determined with reference method. The signal for antioxidants was isolated from the signal to the other analytes in the sample by applying MCR-ALS to the NIR spectra. The relative intensity profile related to the antioxidants was employed in a pseudo-univariate calibration against the %RSA obtained by the reference conventional method based on DPPH. The results of the %RSA determination in four independent samples with mean %RSA (obtained by the reference method) of 90.26% show a mean %RSA of 87.5%, showing the possibility of %RSA determination directly from NIR spectra of turmeric powder extracts by using the multivariate resolution method MCR-ALS.
