Abstract: A new triterpenoid, 11α-O-trans-p-coumaroyltaraxerol (1), along with 11 known triterpenoids, taraxerone (2), taraxerol (3), 2α,3β,23,24-tetrahydroxyolean-12-en-28-oic acid (4), oleanolic acid (5), β-amyrin (6), 3β,23-dihydroxylursan-12-en-28-oic acid (7), 2α,3β-dihydroxyursan-12-en-28-oic acid (8), 2α,3β,23-trihydroxyursan-12-en-28-oic acid (9), 2α,3β,24-trihydroxyursan-12-en-28-oic acid (10), ursolic acid (11), and 3-O-acetylursolic acid (12), was isolated from Craibiodendron henryi W. W. Smith (Ericaceae). The structures of these compounds were elucidated on the basis of spectral evidence. Antioxidant activity and vasodilator effect of compound 1 were assessed.

Key words: Craibiodendron henryi W. W. Smith, Ericaceae, triterpenoids.
