Abstract

Abstract: Ultraviolet (UV) spectrum, infrared (IR) spectrum, mass (MS) spectra and nuclear magnetic resonance (NMR) spectra (i.e., ¹H NMR, ¹³C NMR, DEPT, ¹H-¹H COSY, NOE, ¹H-¹³C HSQC and ¹H-¹³C HMBC) of Triptophnolide were collected and interpreted. All ¹H and ¹³C NMR signals were assigned. Base on the data, the structure of reference standard Triptophnolide was determined.

Key words: assignment, chemical shift, nuclear magnetic resonance (NMR), Triptophnolide, structural elucidation
