Cinchona species were widely used as ancient medicines for different diseases because they contain the active component quinine and its derivatives. However, studies on the molecular aspects of cinchona, including its genetic diversity, have not been reported because most previous works focused on the administration of the antimalarial cinchona alkaloid. Quinine is also being tested as alternative compound for the treatment of Covid-19. The Junghuhn Natural Reserve in Indonesia contains three different types of cinchona plants, namely, Cinchona calisaya, Cinchona pubescens, and Cinchona sp. Given that the genetic diversity and kinship of these species have never been studied, collecting data on the cinchona gene pool has become imperative. This study analyzed the genetic diversity of the cinchona species in the Junghuhn Natural Reserve, Indonesia, by using eight RAPD markers, i.e., OPA-2, OPA-9, OPB-02, OPB-03, OPB-04, OPB-05, OPB-7, and OPJ-07, during 2020 at the University of Jenderal Soedirman, Purwokerto-Indonesia. Polymorphic band data were obtained. Then, phenogram analysis was conducted by using UPGMA and maximum parsimony with MEGA7. The RAPD profiles of Cinchona species (C. calisaya, C. pubescent, and Cinchona sp.) revealed polymorphism with different markers, i.e., OPA-2 (90%), OPB-2 (75%), OPB-5 (75%), OPB-3 (66.66%), OPB-4 (66.66%), OPB-7 (66.66%), OPJ-7 (66.66%), and OPA-9 (58.33%) sequentially with total polymorphism (70.62%). C. calisaya was identified as the most distinctive species. UPGMA yielded a coefficient of 0.200 and two distinctive groups: Group I, which comprised C. pubescens and Cinchona sp. with the p-distance value of 0.333, and Group II, which contained C. calisaya. Ixora sp. was treated as an outgroup plant. The topology of the dendrogram was consistent with that of the UPGMA dendrogram. Results may be used for the further exploration of the genetic diversity of cinchona species.

Abstract C. pubescens is a source of the drug quinine, used to control the effects of malaria, and Cinchona bark was being used in Europe as a treatment for malaria as early as the 1650s, before the plant was authenticated botanically (Raintree, 2003). The Jesuits had introduced it from the New World, hence the name Jesuit's bark or powder (Prendergast and Dolley, 2001). The bark was collected in its native Andean range and probably comprised a mixture of species including C. pubescens. The native range of C. pubescens extends from Andean South America in Bolivia north to Costa Rica. It was widely distributed throughout the tropics as a source of quinine, particularly by the British during the latter half of the 1800s (Moureau, 1945) and is probably still held in many tropical botanical gardens worldwide for its medicinal interest.

Nowadays, COVID-19 cases are growing worldwide, and there is no evidence of an effective drug to combat the new SARS-CoV-2 virus. In this sense, medicinal plants as an alternative treatment are being used without control to handle the pandemic situation. Therefore, bioactive compounds against Coronavirus of medicinal plant species that grow in Ecuador are discussed. The plant species described in this review are Azadirachta indica, Cinchona pubescens, Coriandrum sativum, Cúrcuma longa, Eucalyptus spp, Morus alba, and Salvia rosmarinus[A3] ; and compunds are curcumin, coriandrin, deoxynojirimycin, kuwanon G, mulberroside A, oleanolic acid, rosmarinic acid, ursolic acid, quinine, eucalyptol, and jensenone.

La hidroxicloroquina es un antiguo fármaco proveniente del árbol de quino (Cinchona pubescens), a partir del componente químico alcaloide llamado quinina. Sus primeros usos se documentaron en el Imperio Inca del Perú. Se caracteriza por distintos efectos beneficiosos en enfermedades inmunológicas, al disminuir los procesos de autoinflamación y autoinmunidad persistente. Esta revisión se enfoca en describir los mecanismos inmunomoduladores de la hidroxicloroquina, así como los efectos del fármaco en algunas de las enfermedades autoinmunes más prevalentes: lupus eritematoso sistémico, artritis reumatoide, síndrome de Sjögren, vasculitis sistémicas, nefropatía por IgA, síndrome antifosfolípido, distintas enfermedades inmunológicas de la piel. También se revisarán los efectos adversos descritos para este fármaco, especialmente la toxicidad de retina, que es el más temido. Descriptores: hidroxicloroquina, quinina, autoinmunidad, receptores Toll-Like, enfermedades de la retina.

Cinchona pubscens Vahl. es una especie forestal de gran valor medicinal, comercial y ecológica que se encuentra distribuida desde Costa Rica hasta el Perú y que, por la alteración de su hábitat y la difícil germinación de sus semillas en campo, se encuentra en peligro de extinción. En este trabajo se evaluó el efecto del ácido giberélico, nitrato de potasio y agua de coco en la germinación de sus semillas en material colectado en las montañas del distrito de Colasay (Jaén, Perú). El nitrato de potasio actúo como un promotor en la aceleración de la germinación de las semillas. La concentración 1000 ppm brindó el más alto porcentaje de germinación, energía germinativa y valor de germinación; en cambio, el tratamiento con AG3 a las concentraciones de 1000, 2000 y 3000 ppm inhibió la germinación de estas semillas; y no se justifica una alta inversión en la adquisición del ácido giberélico, cuando se puede implementar un sistema fácil y económico, como es el tratamiento con KNO3
