Concept of Natural Product Chemistry

The present book comprises three parts, Part-A, Part-B & Part-C. Part A describes the isolation and structure elucidation of three new compounds from Cotoneaster racemiflora Desf. In addition seven known compounds have also been described which are reported for the first time from this species. Part-B describes the isolation and structure elucidation of two new compounds from the whole plant of Buddleja crispa Benth. In addition, three known compounds have also been described, which are reported for the first time from this species. Part-C described the synthesis of macrocycle β-sheet (monovalent and divalent Tau peptide) that inhibits aggregation of Alzheimer's related peptides.
