Cassane diterpenes from Caesalpinia bonducella

The Isolation and Structure Elucidation of New Cassane Diterpene-Acids from Caesalpinia crista L. (Fabaceae), and Review on the Nomenclature of some Caesalpinia Species

“…DANDY et EXELL (also under the name of its synonymous name C. bonducella), [5][6][7][8][9] and C. pulcherrima (L.) SWARTZ [10][11][12][13][14][15] of medicinal value among the genus, which revealed the presence of characteristic furano-diterpenes phytochemically classified as cassane diterpenes and otherwise known as caesalpins. We also undertook chemical studies on C. bonduc seeds that have been reputed in both Indonesian and Philippine traditional medicine, and reported the isolation of a new type of hemiacetal diterpenes fused with an a,b-butenolide ring for which the general skeletal name of neocaesalpins was proposed.…”

Cassane Diterpene‐Lactones from the Seed of Caesalpinia minax Hance.

“…Theses diterpenoids can be classified into eight categories: caesalpin, e.g., 14-deoxy-e-caesalpin [1]; neocaesalpin, e.g., neocaesalpin H [2]; caesaldekarin, e.g., caesaldekarin G [3]; caesalpinin, e.g., caesalpinin H [4]; caesalmin, e.g., caesalmin A [5]; bonducellin, e.g., bonducellpin D [6]; norcaesalpinin, e.g., norcaesalpinin F [4], and macrocaesalmin [4]. -The genus Caesalpinia is a rich source of cassane diterpenoids.…”

Caesaldecan, a Cassane Diterpenoid from the Leaves of Caesalpinia decapetala

“…Cassane diterpenoids in which the C-13 methyl group has migrated to C-14 are common. 7,10,12) However, the isoprene moiety has not been found previously in Caesalpinia species. The eight known compounds were identified as spathulenol (2) (3), 14) squalene (4), 15) lupeol (5), 16) trans-resveratrol (6), 17) quercetin (7), 18) astragalin (8), 19) and stigmasterol (9) 20) by comparison of the 1 H-, 13 C-NMR, and MS data with those reported in the literature.…”
