Understanding the chemotype
Kavalactones are ranked 1–6 by molecular weight: (1) desmethoxyyangonin, (2) dihydrokavain, (3) yangonin, (4) kavain, (5) dihydromethysticin, and (6) methysticin. A cultivar's chemotype lists them in descending order of abundance.
Boroguru's chemotype is 462135, meaning the most-abundant kavalactone is #4, followed by #6, and so on. Noble cultivars typically lead with 4 (kavain — uplifting) or 2 (dihydrokavain — relaxing). Tudei cultivars disproportionately lead with 5 (dihydromethysticin), which is implicated in the nausea and two-day lethargy that gives tudei its name.
