New cassane-type diterpenoids from Caesalpinia bonduc.
نویسندگان
چکیده
Six new cassane diterpenoids, named caesalls H-M (1-6), were isolated from the seed kernels of Caesalpinia bonduc. Their structures were elucidated on the basis of spectroscopic analysis, mainly NMR and MS. The absolute configurations of compounds 1 and 3 were determined by a single-crystal X-ray study using a mirror CuKα radiation and circular dichroism (CD) spectra, respectively. None of the compounds were cytotoxic against HepG-2, MCF-7 and MG-63 cells.

Petroleum ether extract of Caesalpinia bonduc L. (Roxb) seeds (Family: Caesalpiniaceae) was evaluated for its anti-inflammatory activity in rats. Wistar rats (120-150 g) of either sex were pretreated with petroleum ether extract of seed kernel of C. bonduc. Inflammation was induced in rat paw by injecting 0.1 ml of carrageenan (1% w/v) in subplantar region of right hind paw. Inflammation induce...
متن کاملCassane-type diterpenoids from the genus Caesalpinia
Caesalpinia is the name of a genus of enormous size and of ancient origin. It is named after the Italian naturalist, Andreas Caesalpino, of Arezzo (1519-1603). He was also a botanical collector, systematist and philosopher, chief physician to Pope Clement VIII, and a professor of medicine and botany in Pisa and Rome.[1] Caesalpinia consists of about 200 species, consisting of shrubs, tall climb...
