so mexican oregano is the highest on the chart but regular isnt. thats interesting... anyway i remember another chart stating chamomile has some of the highest apigenin and luteolin out there. i guess one has to go through 10 charts over 10 years to make the definitive choice here

IIRC, the USDA database already is an aggregate of values from published research, rather than that from any standardized procedure. Extraction procedures vary, as do quantitative measurement techniques. I consider all comparisons from aggregated databases (there are many, usually produced to estimate intakes in epidemiology studies) as very approximate. If you want more likely relative (if not absolute) values, look for individual analytic chemistry studies where the same lab uses the same procedures on your compounds of interest.

Origanum vulgare (Mediterranean "true" oregano) and Lippia graveolens (Mexican oregano) are rather distantly related, different genus and family. They diverged in the late Cretaceous.

thanks darryl i understand but ive seen few more charts in the past with different results. its hard for me to take serious one. not sure maybe the machines are better at estimation this time? or what. im always confused by charts because they keep changing. yet, people are likely to be hooked on that one chart with still questionable results
