Terpenoids from Sladenia celastrifolia

doi:A

Abstract

Abstract: A new C9 seco-iridoid sladeniafolin A (1), together with fourteen known compounds were isolated from the ethanol extract of Sladenia celastrifolia Kurz for the first time. On the basis of spectral data, the known compounds were identified as grasshopper ketone (2), (3S,5R,6S,7E,9R)-7-megastigmene-3,6,9-triol (3), hedytriol (4), (3S,5R,6R,7E,9R)-3,5,6,9-tetrahydroxy-7-megastigmene (5), 1′S*,4′R*-8-(4′-hydroxy-2′,6′,6′-trimethylcyclohex-2-enyl)-6-methyloct-3E,5E,7E-trien-2-one (6), 2α,3α,19α,23-tetrahydroxyurs-12-en -28-oic acid (7), 2α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid (8), pomolic acid (9), 3-O-acetyl pomolic acid (10), ursaldehyde (11), camarolide (12), 3β-hydroxyurs-11-en-13β(28)-olide (13), 3β-hydroxy-11α,12α-epoxy-urs-13β,28-olide (14) and 28-O-β-D- glucopyranosyl euscaphic acid (15) .

Key words: Sladenia celastrifolia, seco-iridoid, sesquiterpenoid, triterpenoid
