Yeputaoteng / Ampelopsis sinica

Just came across an abstract about an interesting Chinese herb:
http://www.ncbi.nlm....pubmed/23616429
Yeputaoteng is the dried ground part of Ampelopsis sinica (Miq.) W.T. Wang, which is widely used in traditional Chinese medicine for preventing and treating tumors, chronic nephritis, hepatitis, rubella, traumatic bleeding, stomach heat and vomiting. A simple and reliable method using high-performance liquid chromatography with diode array detection (HPLC–DAD) was developed for the simultaneous determination of dihydromyricetin and resveratrol in Yeputaoteng.
Seems its main 2 active ingredients are dihydromyricetin and resveratrol. I vaguely recall dihydromyricetin being mentioned with regard to treatment of chronic alcoholism, but it looks like there's more to it...

I also saw references and letters to the editor regarding an article on the similarities between dihydromyricetin and resveratrol but its all behind a paywall. Oral bio-availability is similarly low but this abstract mentions a dramatic increase complexing it with cyclodextrin: http://onlinelibrary...0577.x/abstract

Hi Hav,
I just entered "dihydromyricetin" into my email and did a search.... (I get emails constantly from material suppliers)
Yup, there are lots of suppliers of mine who appear to have this material in both 50% and 98% purity.
I haven't read the links much, but what is your opinion on it?

Hi, Anthony. I haven't tried it yet myself but I happened upon a small sample the other day which sparked my interest. I'm planning on mortar an pestling it with an equal amount of beta-cyclodextrin. The long history of Yeputaoteng and the more recent research on dihydromyricetin all look really promising, although the only general interest I see relates to anti-hangover. There's some even more interesting looking material related to a non-alcohol human trial of glucose & lipid metabolism behind a paywall you might want to also check out if you have access... it seems to have initiated a letter to the editor and an author reply... but I only have access to the abstract. Here are some links:

I don't have have the ability to test or measure glucose level effects of the mix myself but hope to share it with someone who does.

The end of the month steals a lot a time away from things, so I may need to circle around to this when I have a little more time, but it does look interesting.... anti- hangover?
Hmm...
