Antimicrobial activity and phytochemical screening of various parts of Ixora coccinea
Ixora coccinea L. (Rubiaceae) has been used traditionally for a variety of ailments and also cultivated for ornamental purposes. The present study investigated antimicrobial activity of methanolic extracts of various parts of I. coccinea and determined the chemical groups of the active constituents. Antimicrobial activity was assessed using agar disc diffusion, microdilution and thin layer chromatography (TLC)...

New cultivation approaches of Artemisia annua L. for a sustainable production of the antimalarial drug artemisinin
Artemisia annua L. is an important medicinal plant from which artemisinin was extracted to treat malaria effectively. Artemisinin is isolated from the aerial part of the A. annua harvesting from the wild is causing loss of genetic diversity and habitat destruction. The use of controlled environments can overcome cultivation difficulties and could be a means to manipulate phenotypic variation in bioactive compounds and...
