If you keep numbering around the A ring, the 6 position is equivalent to 1, and the 7 equivalent to 2. Highly irregular nomenclature, but then Maxwatt is an avid cyclist, so he's used to giving the wheel a spin.
Note that Maxwatt actually corrected this in an earlier post and I was just correcting my previous mistake.
Note also that it's tetra, not tetera.
Oops! That'l teach me to copy-paste!
This paper is interesting because of the melanogenesis- it provides a hint that Mr. He was on to something, but he'd better take a boatload of it, because they're seeing this effect at around 30 uM, a level that would be hard for this kind of compound to reach in vivo. There are a lot of other things in He Shou Wu as well. Aside from legend, I have a suspicion that it doesn't work very well as a hair color restorer, or you'd find it in every WalMart on the planet.
Legend has it that Mr. He was an old soak who left his village in a huff and no-one was sorry to see him go.
He then lived exclusivly on this plant for quite some time.
Perhaps just maybe fasting and only eating one thing exclusively somehow makes more of it available. Mayhaps the body is less fussy about what it abzorbs when its starvng.. or something?
The big question though is; can we find the paper that shows 2, 3, 5, 4'-tetrahydroxystilbene to be a breaker of pentosidine AGEs???
