%X In addition to alphitonin and ceanothic acid, the wood of Alphitonia excelsa Reiss. also contains betulic acid. The wood of A. petriei Braid &amp; White yields in addition to these substances, alphitolic acid and &#946;-sitosterol, but the wood of A. whitei Braid is rather different, containing maesopsin instead of alphitonin. There is also present ceanothic acid, betulic acid, alphitolic acid, betulin, and &#946;-sitosterol.   The structures of maesopsin and alphitolic acid are deduced.
