“…Time periods of 36 and 48h were suffi cient to stimulate the accumulation of these compounds (14.6 and 13.9mg of amaranthine 100gMF -1 , respectively) when compared to the control (3.7mg of amaranthine 100gMF -1 ) ( Figure 1A). However, the observed concentrations of betacyanins were much lower than those found by KLEINOWSKI et al (2014) in the stems of the same species: 36.95mg of amaranthine 100g MF -1 with tyrosine elicitation (75µM). This response might be due to the type of plant material and elicitor used in the analyses.…”

“…Alternanthera tenella Colla (joyweed) is a weed that occurs in crops and uncultivated areas in northwest Brazil but also in other regions, like the state of São Paulo [ 85 , 96 , 97 ]. A. tenella has been used in popular medicine to treat the infections, fevers, bruises and itches [ 98 , 99 ]. The plant has been also used as diuretic [ 100 , 101 ].…”

“…Both increased with the addition of salicylic acid to the culture medium. In order to enhance the production of betalains, some authors assayed the action of tyrosine added to the in vitro cultures of A. tenella [ 98 ]. The authors reported a negative effect on in vitro growth of this species, affecting the formation of shoot and roots, nevertheless increased the biosynthesis of betacyanins, measured as total amaranthin.…”

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.

“…De forma similar, Kleinowski et al (17) y Fang et al (18) encontraron una importante proporción de glicósidos en extractos de Alternanthera philoxeroides, destacando su papel en los efectos antitumorales y antivirales observados in vitro. Es así que incluso, Hundiwale et al consideran que la presencia de glicósidos es una característica del género Alternanthera (4) .…”

Objetivos. Caracterizar compuestos fenolicos presentes en el extracto etanolico de las hojas de Alternanthera lanceolata (Benth.) Schinz "lancetilla". Materiales y Metodos. Se preparo un extracto etanolico de las hojas de Alternanthera lanceolata (Benth.) Schinz "lancetilla". Se evaluo la solubilidad del extracto en solventes de polaridad creciente. Se detectaron los componentes quimicos del extracto etanolico mediante un tamizaje fitoquimico empleando gelatina, tricloruro ferrico, reaccion de Shinoda, entre otros. Se realizo cromatografia en capa fina, desorcion y propuesta de estructuras quimicas para los metabolitos tipo flavonoides presentes en el extracto etanolico de hojas de Alternanthera lanceolata (Benth.) Schinz "lancetilla" mediante espectroscopia UV-Vis. Resultados. El extracto etanolico presento mejor solubilidad en solventes de mediana polaridad. El tamizaje fitoquimico dio resultados positivos para presencia de compuestos fenolicos, flavonoides y glicosidos. Se propuso la estructura quimica de siete flavonas en el extracto investigado. Conclusiones. Se caracterizo y propuso las estructuras de compuestos fenolicos tipo flavonas en el extracto etanolico de las hojas de Alternanthera lanceolata (Benth.) Schinz "lancetilla".
