Existing Kavalactone Methods

▪ NIR Spectroscopy ▪ For routine analysis of dry export material ▪ Reportedly helpful in determining chemotype ▪ NIR predictions correlate well to HPLC values

Existing Kavalactone Methods

▪ FTIR (and GC) ▪ Determines the content of six kavalactones ▪ Enables assignment of chemotype ▪ Partial least square regression used to model ▪ Comparable to GC
