I think Matcha might have a high level of that?
I get a happy caffine high from that particular kind of tea.
but, that's just me personally.
uhh uhh... Apparently its strong in Green Teas.

I was hoping some of the black teas would be high in MAOIs - anybody know? Thanks SilentSliper.

iirc Darjeelings have the most MAOIs of the black teas.

There are MAOIs in tea? I don't think tea contains any MAO inhibitors... I could be wrong though. Could you provide the source that told you this?

I'd be curious about this as well.

catechin and epicatechin are selective MAO-B Inhibitors
this study is about MAO-B activity of catechins in cats claw but epicatechin is also present in tea

numerous studies can be found using Google Scholar, keywords:
tea catechins polyphenols mao-b inhibitors
catechins (aka 'tannins') can be found in chocolate, wine, other fruits & veggies

Results of this investigation indicate that most of samples can attenuate peroxide production by inhibiting the deamination of monoamines as a scavenger, regardless of the methods o f processing and provinces of cultivation.
It was also shown to inhibit non-competitively both MAO-A and MAO-B with the IC50 so values. It is concluded that some Chinese green teas may be useful in the prevention/treatment o f neurodegenerative diseases
relating to in vitro MAO inhibitory activities. The structure-activity relationship examination should be followed
for further research..
There is a co in Japan that produces a concentrated extract of green tea with higher levels of these polyphenols thought to be beneficial.
