Spektraris: A collection of tools for identifying plant natural products

Spektraris currently consists of two databases. An LC-MS Accurate Mass - Time tag (AMT) database, and an NMR database.


  • Spektraris AMT Database - Resource for searching LC-MS data againast a database of plant natural products.
  • Spektraris NMR Database - Resource for searching 1H and 13C NMR data against a database of plant natural products, currently focused on compounds related to Paclitaxel.
