“…Anthocyanins are located predominantly in the epidermal, hypodermal, and superficial cortical layers of adventitious roots in M. excelsa. Similar histological distributions have been observed in some Impatiens species (Thakur & Nozzolillo 1978). Our results also highlight variability in the distribution Pattern of anthocyanins among mature root tissues.…”

“…By contrast, the flowers of M. excelsa contain up to 11 anthocyanins based on Cy, Dp, Mv, Pn, and Pt (Cambie & Seelye 1961;Anderson 1988). Cy has been found also in roots of Impatiens species (Thakur & Nozzolillo 1978), and Cy and Pg were reported to be present in the roots of different varieties of Raphanus sativus (Harborne 1963;Ishikura & Hayashi 1962, 1963. The glycoside components of root anthocyanins in M. excelsa require identification.…”

Anthocyanin pigmentation is a prominent feature in the adventitious roots Of Metrosideros excelsa. We describe the histological distributions and chemical nature of anthocyanins in these roots, and quantify their antioxidant activity. Anthocyanins were present in one or more cell layers of the root cap, epidermis, hypodermis, and cortex. A narrow band immediately behind the root apex was usually anthocyanin free. Photosensitivity of anthocyanin biosynthesis was evident both for adventitious roots and for plagiotropic roots exposed at the soil surface. The anthocyanins were cyanidin-and delphinidinbased. Methanolic extracts of the roots did not show a direct relationship between anthocyanin concentration and antioxidant activity. The possible function of anthocyanins in these roots is unknown.Abbreviations PC = paper chromatography, TLC = thin layer chromatography, DPPH = a,a-diphenyl-P-picrylhydrazyl, Cy = cyanidin, Dp = delphinidin, Pg = pelargonidin, Pn = peonidin, Pt = petunidin, Mv = malvidin

“…In the roots of Metrosideros excelsa exposed to light cyanidin and delphinidin were found (Solangaarachchi and Gould, 2001). Cyanidin was also identified in the roots of Impatiens (Thakur and Nozzolillo, 1978) and the presence of cyanidin and pelargonidin was recorded in the roots of Raphanus sativus (Harborne, 1963;Ishikura and Hayashi, 1962). Cyanidin is the most common among plants.…”

“…Accumulation of anthocyanin in roots exposed to daylight has been observed in Salix and Zea (Tselas et al, 1979), Fragaria × ananasa (Nemec, 1973), Impatiens spp. (Thakur and Nozzolillo, 1978) and in Metrosideros excelsa (Solangaarachchi and Gould, 2001). Shimizu et al (2010) reported that light irradiation was essential for anthocyanin accumulation induced by JA-Me treatment in Gynura bicolor cultured roots.…”

The influence of methyl jasmonate on anthocyanin accumulation in roots of Kalanchoe blossfediana plants was studied. Methyl jasmonate (JA-Me), at a concentration of 5.0 to 40.0 mg.l -1 , substantially increased anthocyanin accumulation in roots of intact plants, when it was applied as a solution under natural light conditions. The production of anthocyanin depended on the concentration of methyl jasmonate and the age of the plant. The stimulatory effect was higher in older plants of K. blossfeldiana than in younger ones. When leaves were removed methyl jasmonate slightly stimulated anthocyanin accumulation compared with intact plants. The obtained results indicate that leaves are necessary for the anthocyanin accumulation in the roots. In isolated roots methyl jasmonate did not affect the accumulation of anthocyanins in light conditions. Seven anthocyanins were documented in the roots of control plants and 8 anthocyanins in the roots of JA-Me treated ones. JA-Me increased the level of anthocyanins in roots of old K. blossfeldiana plants 6.8, 6.0 and 3.6-folds, after 4, 8 and 14-days of treatment, respectively.

Background:The market for edible flowers has grown exponentially due to consumers demand. This has been motivated by the concern to include healthier foods in the daily diet, leading to a great interest in these natural matrices. However, and although the consumption of this type of matrices are popularly associated with health benefits, scientific studies are still scarce. The industry seeks to satisfy the consumers demands and, at the same time, seeks to launch new challenges in the sector, in order to outline new conservation and production strategies. Although there are several flowers with edible potential in nature, many are still little explored or unnoticed, so this type of study is increasingly sought after. Scope and approach: The present review intendeds to explore the context of edible flowers as well as their conditions of production and consumption. Then, focusing on the characterization of the genus Impatiens, which, although is still little explored, gathers data on its chemical and nutritional characterization, bioactivities, and the possible exploration of natural pigments and industrial application. Key findings and conclusions: Several studies have been focused on the chemical characterization of flowers, evaluation their edibility, as well as validating their bioactive potential. In particular, the genus Impatiens is characterized by presenting perennial and succulent herbs with attractive colors, normally found in tropical forests. There are countless studies on the bioactive activities present in these edible flowers. In addition, its pigmentation has a direct relationship with the presence of several compounds, especially anthocyanins and their derivatives. These bioactive compounds have a great interest to the food industry and consumers, due to their diverse health benefits that are provided by their regular consumption.
