• 論文の詳細を見る

• The leaves of Barringtonia asiatica afforded two new triterpenes, germanicol caffeoyl ester (1) and camelliagenone (2). Their structures were elucidated by extensive 1D- and 2D-NMR spectroscopy. It also afforded germanicol trans-coumaroyl ester (3), germanicol cis-coumaroyl ester (4), germanicol (5), camelliagenin A (6), spinasterol, sitosterol, squalene, lutein and trilinolein. Compounds 3, spinasterol and trilinolein were isolated from the fruits, while the seeds yielded spinasterol, squalene, linoleic acid and trilinolein. Compounds 1—5 exhibited antifungal activity against Candida albicans, 1—3 and 5 showed antibacterial activity against Staphylococcus aureus, while 5 is active against Pseudomonas aeruginosa.
