从肋果茶(Sladenia celastrifolia)95%乙醇提取物的乙酸乙酯部位中分离得到15个萜类化合物,经波谱学方法分别鉴定为sladeniafolin A(1),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-oicacid(7),2α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid(8),pomolic acid(9),3-O-acetyl pomolic acid(10),urs-aldehyde(11),camarolide(12),3β-hydroxyurs-11-en-13β(28)-olide(13),3β-hydroxy-11α,12α-epoxy-urs-13β,28-olide(14)和28-O-β-D-glucopyranosyl euscaphic acid(15)。以上化合物均首次从该植物中分离得到,其中1为新的C9裂环烯醚萜。
Fifteen terpenoids were isolated from the ethyl acetate fraction of 95% ethanol extract of Sladenia celastrifolia and identified by spectroscopy as sladeniafolin A (1), 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-oicacid (7), 2α, 3β, 19α, 23- tetrahydroxyurs- 3-O-acetyl pomolic acid (10), urs-aldehyde (11), camarolide (12), 3β-hydroxyurs- hydroxy-11α, 12α-epoxy-urs-13β, 28-olide (14) and 28-O-β-D-glucopyranosyl euscaphic acid (15). The above compounds were isolated from this plant for the first time, of which 1 is a new C9 secoiridoid.
