“…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.…”

New cassane diterpene-acids, neocaesalpins H and I, were isolated from the leaves of Caesalpinia crista (Fabaceae), and their structures were deduced on the basis of the spectroscopic and chemical basis. These compounds were characterized as having an a a,b b-butenolide hemiacetal ring that is rare in nature. The lacking of 5-hydroxy group also distinguished neocaesalpins H and I from cassane diterpenes (caesalpins) occurring in other Caesalpinia species from the phytochemical viewpoint. The nomenclature of three Caesalpinia species was also reviewed, and it was found that some species belonging to the genus Caesalpinia are improperly named and should be changed to valid names.

“…Caesalpinia sp. has a propensity for producing cassane furanoditerpenes (Kinoshita et al, 2005;Kaluni et al, 2005;Lyder et al, 1998a;Jiang et al, 2001;Linn et al, 2005;Ragasa et al, 2002;Jiang et al, 2002;Roengsumran et al, 1998). Among cassane diterpenes production of the cassane butenolides or butenolide hemiketals is possibly via photooxygenation of the furan ring and these compounds have very limited distribution (Lyder et al, 1998b;Torres-Mendoza et al, 2004;Roach et al, 2003;Kinoshita et al, 2005;Jiang et al, 2002).…”

“…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.…”

“…Phytochemical studies on the seed of Caesalpinia minax Hance have led to the isolation of five new cassane-diterpene-lactones, named neocaesalpin J -N (1)(2)(3)(4)(5)resp;Fig. 1), and together with nine known furanoditerpenoids, i.e., e-caesalpin, 7-acetoxy-ecaesalpin, 14-deoxy-e-caesalpin [1], caesalmin D -F [10], bonducellin C -D [6], and neocaesalpin A [11].…”
