TL;DR: The cis-isomer of ebelin lactone was obtained as one of the artefacts of the aglycone and its structure revised, and the structure was established as 3-beta-[O-beta-D-glucopyranosyl(1-->3)-O- [alpha-L-arabinofuranosyl)oxy]jujubogenin by chemical and spectral analyses.

TL;DR: Research carried out using different in vitro and in vivo techniques of biological evaluation support most of the claims of Streblus asper Lour for treatment of different ailments.

TL;DR: A triterpene, methyl 3-epi-betulinate in its native form and 4′,6′-dihydroxy-2′-methoxy-3′,5′-dimethyl chalcone along with ursolic acid, jacoumaric acid and arjunolic acid have been isolated from the aerial parts of Syzygium samarangense as mentioned in this paper.

TL;DR: An investigation of Dodonaea viscosa afforded a new flavonoid having an isoprenoid side chain along with the seven known flavonoids: 5-hydroxy-3,6,
