The Aronia genus (Rosaceae family, Maloideae subfamily) includes two species of native North American shrubs: Aronia melanocarpa (Michx.) Ell. (black chokeberry) and Aronia arbutifolia (L.) Pers. (red chokeberry). The fruits of A. melanocarpa have been traditionally used by Potawatomi Native Americans to cure colds. In the first half of the 20(th) century, cultivars of black chokeberry were introduced to the Soviet Union and other European countries, providing fruits used by food industry. At present, it is used mainly for juice, jam, and wine production, as well as an ornamental plant. Among other substances, the berries of A. melanocarpa contain anthocyanins and procyanidins, possessing strong antioxidative potential. Numerous health-promoting activities-namely, antioxidative, antimutagenic, anticancer, cardioprotective, hepatoprotective, gastroprotective, antidiabetic, anti-inflammatory, antibacterial, antiviral, radioprotective, and immunomodulatory-have been demonstrated for black chokeberry extracts by both in vitro and in in vivo studies. The presented review summarizes the information concerning botany, cultivation, chemical composition, and pharmacological activities of Aronia plants.
Hairy root cultures of Hyoscyamus niger were cultivated in shake-flasks, a bubble-column bioreactor and a hybrid bubble-column/spray bioreactor and evaluated for alkaloid production. The latter gave the highest anisodamine content (0.67 mg/g dry wt) whereas scopolamine, hyoscyamine and cuscohygrine concentrations were highest in the bubble-column reactor (5.3, 1.6 and 26.5 mg/g dry wt, respectively). Both bioreactors gave similar productivities of scopolamine (1 and 0.98 mg/l day) and cuscohygrine (5 and 5.4 mg/l day), but anisodamine productivity was 3.5-fold higher in the hybrid bioreactor (HB) (0.02 and 0.07 mg/l day, respectively). Elicitation with methyl jasmonate increased scopolamine productivity by 146 % in roots grown in the HB whereas their permeabilization with DMSO caused 4-, 5-, 25- and 28-fold increase in scopolamine, hyoscyamine, anisodamine and cuscohygrine concentrations in the growth medium. In situ extraction with Amberlite XAD-2 doubled scopolamine productivity in the hybrid reactor after 50 days.
This method can be recommended for quantitation of hyoscyamine, scopolamine, anisodamine, littorine and cuscohygrine in different plant material (field grown vs. in vitro cultures).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
