Cassane-type diterpenoids from Caesalpinia latisiliqua (Cav.) Hattink

Chemical Constituents of Caesalpinia bonduc

“…13 C-NMR (CD3OD) see Table 1. protocatechuic acid (7) Yellowish-white powder molecular formula C7H6O4…”

“…The known compounds 6-8 were identified as (+)-isolariciresinol (6), protocatechuic acid (7), and methyl gallate (8), respectively, by extensive analysis of their ESI-MS, 1 H-and 13 C-NMR data, as well as comparison with those reported [13][14][15].…”

“…Some species of Caesalpinia genus such as C. bonduc, C. sappan have been commonly used in traditional medicine for a long time as functional food, supporting the prevention of some diseases such as rheumatism, back pain, antipyretic around the world [1,4,5]. Previous studies showed that the chemical constituents of the Caesalpinia genus contained a diversity of secondary metabolites such as lignans, _______ https://doi.org/10.25073/2588-1140/vnunst.5500 flavonoids, and terpenes [3,6,7]. They have a variety of characteristic biological activities like anti-inflammatory, anti-oxidant, anti-bacterial, and anti-diabetes [3,4,[6][7][8].…”

In Vietnam, there have been only a few phytochemical investigations of C. bonduc [1].…”
