“…This result corresponds to the findings recently reported by Herlt et al for two other saponins found in Barringtonia asiatica. 12 Furthermore, the 13 C-NMR signals of these reported glycones show very close agreement with the sugar portion of ranuncoside VIII.…”

“…show antibacterial and antifungal activity, 10,11 there is very little work reported on compounds isolated from Barringtonia asiatica, except for a very recent report citing two new saponins isolated from the seeds of this plant, neither of which is credited with the piscicidal activity of the seeds. 12 We wish now to report the structure of the principle piscicidal compound present in this species.…”

Barringtonia asiatica, commonly known as botong is found along the seashore throughout the Philippines. The fruits and seeds of B. asiatica are used as fish poison, fruit juice for scabies, leaves are applied to stomachache and rheumatism, seeds as vermifuge, and bark for tuberculosis. 1)The aqueous crude extract of B. asiatica seeds exhibited high biological activity in the brine shrimp hatchability and lethality assay.2) The crude methanolic extract of B. asiatica (leaves, fruits, seeds, stem and root barks) and the fractions (petrol, dichloromethane, ethyl acetate, butanol) exhibited a broad spectrum antibacterial activity, while a number of fractions demonstrated antifungal activity.3) Two major saponins from the seeds of B. asiatica are putative antifeedants toward Epilachna sp. larvae.4) The seeds of B. asiatica were reported to exhibit piscicidal activity. The major compound responsible for this activity is ranuncoside, an oleanane glycoside. 5)An earlier study also reported the isolation of a mixture of saponins (A 1 -barrinin) from B. asiatica which was hydrolyzed to afford A 1 -barrigenol and A 2 -barrigenol. The latter was identical to camelliagenin A 6) which is of relevance to our present report.We report here the isolation, structure elucidation and antimicrobial assay of two new triterpenes, germanicol caffeoyl ester (1) and camelliagenone (2) from the dichloromethane extracts of the leaves of B. asiatica. The leaves also afforded germanicol trans-coumaroyl ester (3), germanicol ciscoumaroyl ester (4), germanicol (5), camelliagenin A (6) (Fig. 1) 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.

“…The seeds of the plant can be directly used as a natural pesticide (Kardinan, 2005). The methanol extract of derived from the seed of B. asiatica is toxic to larvae of Crocidolomia pavonana F. (Lepidoptera: Pyralidae) (Dono and Sujana, 2007) and to larvae of Epilachna sp (Herlt et al, 2002). The active compounds found in Bitung include saponins, gallic acid, hydrocyanic acid, and triterpenoids consisting of bartogenat acid, 19-epibartogenat acid, and acid-bartogenat anhidro.…”

This study aim was to examine the effectiveness of methanol extract derived from keben seed (B. asiatica) on mortality of Spodopthera litura larvae on soybean plant. The instar II larvae of S. litura were treated by the methanol extract with various concentrations i.e. 0.0 ppm (Control), 0.2 ppm, 0.4 ppm, 0.8 ppm and 1.0 ppm using pre-investment and post-investment. The mortality of larvae S. litura was counted after 24-hours of the treatment. The B. asiatica seed extract was quite effective in suppressing the intensity of damage in leaves caused by the attack of S. litura F. on soybean plants. The finding on pre-investment showed that after 24-hour treatment of methanol extract showed to have a significant impact on the mortality of S. litura instar II. The methanol extract dose 0.2 ppm, 0.4 ppm, 0.8 ppm, and 1.0 ppm had all been able to affect larvae mortality of S. litura there are 33.33%, 48.89%, 66.67%, and 88.89% respectively. Moreover, post-investment experiment showed that the methanol extract also induced mortality of S. litura in all doses, i.e 0.2 ppm, 0.4 ppm, 0.8 ppm and 1.0 ppm caused 44.44% (53.33%) ( 55.56%), (71.11%) mortality, respectively.
