“…Hydrophilic pharmacological components such as cichoric acid and echinacoside were also detected from cell cultures of E. angustifolia (Smith et al 2002), whereas cinnamic acid and caffeic acid were isolated from callus cultures of Echinacea (Sicha et al 1991). Anthocyanins were also extracted from E. pallida and E. purpurea, and identified as cyanidin 3-malonylglucoside (Cheminat et al 1989). Li and Barz (2005) reported that the elicitation of cell culture of E. purpurea with yeast produced two new 8,4′-oxynorneoligans that were not detected in the intact plants and have cytotoxicity to human tumor cells.…”

Echinacea, better known as purple coneflower, has received a global attention because of its increasing medicinal value. There is enormous potential for the discovery of new medicinal compounds in this species and an immediate need for techniques to facilitate the production of high quality, chemically consistent plant material for drug development and clinical trials. In vitro tissue culture of Echinacea can play a vital role in the development of novel germplasm, rapid multiplication, and genetic modifications for an enhanced phytochemical production. Recent establishment of liquid culture techniques, large-scale bioreactors, and Agrobacterium-mediated transformation are changing the production parameters of the Echinacea species. This review provides an overview of the recent developments in in vitro technologies and challenges that remain in the Echinacea biotechnology.

“…[43][44][45] In addition, in regard to the sample purified from the extracts, this substance was identical with the cyanidin-3-O-glucoside, as evidenced by the observed anomeric proton and olefin proton of the glucose moiety. These analytical results were supported by m/z 449 (M + ), and 287 (M + ), corresponding to cyanidin.…”

Recently we found that extracts from ancient rice brans, especially those from black rice bran, possess strong scavenging activities for reactive oxygen species (ROS). In this study, we examined the origin of the ROS-scavenging activities in the black rice bran extracts, and identified candidate scavengers such as cyanidin-3-glucoside (Cy-3-glu) and cyanidin. Although ferulic acid is known to be an antioxidative component of bran in currently available common white rice varieties, it was not found in the black rice bran extracts. The ROS-scavenging activities of Cy-3-glu and cyanidin, which were identified in this study, were examined using the ESR-spin trap method and in terms of protective activity against effects of ultraviolet (UVB) irradiation on an epidermal cell line (HaCaT cell). These anthocyanin compounds were found to possess both strong ROS-scavenging activities and to suppress cell-damaging effects of UVB, indicating that both Cy-3-glu and cyanidin are the active components involved in the antioxidative activity of black rice bran extracts.

“…The hairy root cultures treated with 6 min of ultrasound became more purple than the control without ultrasound treatment. The onset of purple color is related to anthocyanin accumulation and has been shown to exist mainly in the flower of wild E. purpurea plants 24. As shown in Fig.…”
