Opis:
The article covers French aspects of the Cinchona Tree. Mention is made of Louis XIV’s role in introducing medicines with the bark of the Cinchona Tree. The article discusses the description of the Cinchona Tree by the French scientific expedition by Charles-Marie de La Condamine (1701–1744) and Joseph de Jussieu (1704–1779). It mentions the discovery and isolation of quinine by Pierre-Joseph Pelletier (1788–1842) and Joseph Caventou (1795–1877). It also covers French efforts to acclimatise the Cinchona Tree in the colonies.

Opis:
Following the big five of plant families presented by Hammer et al. (2015) an attempt was undertaken to select the big five of crop plants and genes. A large number of species (7 thousand of crops among 250 thousand of higher plants) as well as accepted criteria cause difficulties. Three cereals (wheat, rice, corn), potatoes (source of carbohydrates plus an influence on a history of three states) and soybean (main source of protein in animal feeds) were counted as plants having the greatest im- portance in human nutrition. Considered were also the genes, to a great extent influenced the productivity and use of those crops, making easier cropping and harvesting (genes Rht and Glu in wheat, Sd1 in rice, resistance to herbicide in soyabean), improv- ing grain quality (Glu and Gli in wheat and genes for beta caro- tene synthesis in rice) as well as resistance to pests (Bt in corn) and diseases (R in potatoes). Five species were also presented which played an outstanding role in nations, states or even con- tinents history (cinchona, sugar cane, tee bush, cotton, cocaine bush). According to the authors’ opinion as well as that of Hob- house’s (2005), Molenda’s (2011), and Laws’ (2016) these plants changed the course of the world’s history.

Opis:
Cinchona alkaloids comprising quinine, quinidine, cinchonidine and cinchonine as the major members constitute a unique class of quinoline alkaloids with tremendous impact on human civilization (Section 1). The odyssey of Cinchona alkaloids began with the discovery of their antimalarial properties followed by antiarrhytmic action of quinidine. Currently medicinal chemistry of Cinchona alkaloids derivatives develops rapidly and many other activities such as cytotoxic, multidrug resistance inhibitory have been demonstrated (Section 5) [5]. Beside medicine Cinchona alkaloids gave also the fundaments of stereochemistry and asymmetric synthesis. An extraordinary catalytic potency of parent and modified Cinchona alkaloids (deserving privileged catalyst classification) include more than 50 types of diverse stereoselective reactions, with few spectacular such as asymmetric dihydroxylation of alkenes or heterogeneous α-ketoesters hydrogenation (Section 3) [3]. Last but not least the portfolio of applications of Cinchona alkaloids includes resolution of racemates by diastereomeric crystallization or by the use of Cinchona- -based chiral stationary phases for ion-exchange enantioselective chromatography and other recognition or sensing systems (Section 4) [166]. Easy transformation of Cinchona alkaloids (for example by click chemistry) into other chiral and modular building blocks together with current pressure on a more intense exploration of sustainable products make cinchona alkaloids of primary importance for modern synthetic, catalytic and medicinal chemistry. The aim of this review which covers over 200 references is to briefly summarize all aspects of Cinchona alkaloid chemistry and biology with the special emphasis on new applications.
