Viridis, purslane is the same as the garden weed some people called wild portulaca - it's Portulaca oleracea. I've eaten it lots & like the taste & while it's supposed to be rich in omega-3, think for a minute of where it would be - the seeds.
It's one of the complaints I have against blanket analysis of beneficial plants. Often, what part of the plant is rich in certain nutrients isn't specified so people assume the whole plant is a good source. Only once, did I read that --
"purslane has the highest omega-3 profile of all plants in what small amount of fats is found in purslane"
-- so I think you get an idea of how much is in it. It’s true that chickens that have eaten lots of purslane have higher omega-3 in their eggs, but chickens can eat a lot of purslane & the omega-3 fats are concentrated in the eggs for the developing chicks.Even if little omega-3 is found in purslane, it wouldn't stop me from eating it, I like the taste. But it does have a fair amount of oxalic acid, which can interfere with calcium absorption. It's supposed to have 1.31 g oxalic acid per 100 g purslane - quite high; but then, so does parsley, & it doesn't stop me from eating hummus with lots of parsley.
Here's what I found on purslane:

You can find a lot from the USDA Nutrient Data Lab http://www.nal.usda.gov/fnic/cgi-bin/nut_search.pl
one of the main complaints I have about the Canadian equivalent - very few reference sources for the average person, but the American site is good.--Will write you back soon. I've been very busy too as I'm sure you understand.-- ^_^
