  1. *Rt: Retention time
  2. **SI (Similarity Index): It is the percentage of computer-based spectral matching between the mass spectrum of each unknown peak in the chromatogram to the spectra stored in NIST library database. SI = 100; when two spectra are identical and 0 if they are completely different
  3. ***% Peak Area: It is the relative percentage amount of each component in the extract calculated by comparing its peak area to the total peak areas in the chromatogram
  4. The identity of the most abundant compound 39 needs to be confirmed by further isolation and fractionation
