โฆ Synopsis
Antibacterial activity of petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE) and ethanol (EE) extracts of dried Elaeocarpus sphaericus fruit was investigated against 28 gram-positive and gramnegative bacteria using the disc diffusion and plate dilution methods.
The AE fraction showed marked antimicrobial activity against ten organisms. BE was active against Salmonella typhimurium and Morganella morganii, and EE against Plesiomonas shigelloides, Shigella flexnerii and Sh. sonneii. The alkaloids and flavonoids present in the plant appear to be of chemotherapeutic interest.

Two new indolizidine alkaloids, (AE)-3-oxoisoelaeocarpine ( 1) and (AE)-elaeocarpine N-oxide (2), along with three known alkaloids, (AE)-isoelaeocarpine (3), (AE)-elaeocarpine (4), and (ร)-isoelaeocarpiline (5), were isolated from an EtOH extract of the branches and leaves of Elaeocarpus sphaericus.
treated animals were as follows: histamine, 0.22 zk 0.019 and 0.0098 f 0.0012; oxotremorine, 0.16 f 0.017 and 0.0062 f 0.0004; nicotine, 1.08 f 0.15 and 0.15 f 0.038; and serotonin, 12.8 f 0.29 and 0.12 =t 0.016. The toxicity of histamine was also increased by pretreatment with dichloroisoproterenol
