Cinchona bark Chinese alias: Cinchona bark English name: br () ( .) The dry bark, root bark, branch bark and seeds of the Cinchona tree contain about several kinds of alkaloids, collectively called Cinchona alkaloids . Among them, quinine is the most abundant and most important in medicine, followed by cinchonine, cinchonidine, quinidine, etc. The rest have a very low content in the bark. Most of them are quinoline derivatives, and a few are indole derivatives. Among the cinchoni alkaloids, many are stereoisomers of each other, such as: quinine and quinidine, cinchonine and cinchonidine, cinchotin and cinchamidine, epiquinine and epiquinidine, hydroquinine Ning and hydroquinidine, etc. In addition, there are cinchonidine, quinisine, cuprosine, quinamine, cinchonamine, quinidone, alixin and quinidine, red cinchona base, methyl red cinchona base, and kannadaline.

Growth environment: Cinchona requires an annual average temperature of ℃, an average minimum temperature of .℃, a warm, frost-free climate all year round. It is suitable for planting in the southern area of Yunnan Cinchona Province at an altitude of ~ meters. There is obvious freezing damage when the temperature is ~℃, and when the temperature is lower than ℃, the above-ground parts will be frozen to death. Cinchona trees prefer a rainforest environment with some shade and moisture. Requirements for light intensity vary with changes in air temperature, soil moisture, and air humidity. As the temperature rises, the requirement for shade increases. The smaller the tolerance, the greater the requirement for shade. Generally, planting and growth are good under the conditions of relative air humidity above % and shade degree of %~%, and the content of alkaloids and quinine in the bark is significantly increased. Soils rich in organic matter, deep, loose, well-drained, and high in value are most suitable for its growth. Soils that are too sticky and have too much gravel are not suitable for planting.
