ELUCIDATION OF BIOSYNTHETIC PATHWAY FOR PLANT BIOACTIVES FROM AERIAL PORTION OF GREEN CHIRETA (ANDROGRAPHIS PANICULATA NEES.)M.S. Swetha, S. Haripriya, A. Lakshmanan and Z. John Kennedy
Green chireta, previously known as âking of bittersâ is widely used as a complimentary medicine to treat various types of cancer patients. At present, no direct evidence is available as to the biosynthetic pathway of its unusual skeleton. To provide guidance as to possible biosynthetic precursors, construction of biosynthetic pathway based on the secondary metabolites obtained from green chireta phytochemicals. This paper shows biosynthetic scheme based in sound biosynthetic principles of compounds newly found in nature or those difficult to tackle by conventional means.
