newbie parsing question

[Kun]

i have a list of that is:

[('460 (BODY[HEADER.FIELDS (FROM)] {46}', 'From: Friend 
<anon at anon.com>\r\n\r\n'), ')', ('462 (BODY[HEADER.FIELDS (FROM)] {37}', 
'From: Kun <neurogasm at gmail.com>\r\n\r\n'), ')']


how do i parse the email addresses out of it into another list or string?
