Abstract From tissue culture of Akebia quinata , three new triterpenes were isolated together with two known triterpenes, oleanolic acid and mesembryanthemoidgenic acid. The new triterpenes were characterized by spectroscopic means as 3β-hydroxy-30-norolean-12,20(29)-dien-28-oic acid, 3-epi-30-norolean-12,20(29)-dien-28-oic acid and 3β-hydroxy-29(or 30)-al-olean-12-en-28-oic acid.
