This phytochemical investigation of Caesalpinia bonduc reported eight known compounds, namely threo-2,3-bis(4-hydroxy-3-methoxyphenyl)-3-methoxy-propanol (1), evofolin-B (2), trans-Linalool-3,6-oxide-β-D-glucopyranoside (3), 1-(2-methylbutyryl)phloroglucinol-glucopyranoside (4), 1-(3 methylbutyryl)phloroglucinol-glucopyranoside (5), (+)-isolariciresinol (6), protocatechuic acid (7), methyl gallate (8). The structures of these compounds were identified by 1D- and 2D- nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) and by comparison with those reported in the literature. Compound 2 exhibited significant cytotoxic effects against the HepG2 cell line with an IC50 value of 48.37±3.18 µM.

“…By NMR data analysis and comparison with the reported spectroscopic data, eight known compounds were identified as cyclamiretin A (2), [15] psychotrianoside G (3), [16] 3-hydroxy-β-damascone ( 5), [12] megastigmane ( 6), [17] corchoionol C (7), [18] zingiberoside B (9), [19] angelicoidenol (10), [19] trans-linalool-3,6-oxide-β-D-glucopyranoside (11). [20] At present, most of epoxy moiety in oleanolic-type triterpene existed at C-11 and C-12. In this study, we reported a novel oleanolic-type triterpene from A. crispa with a rare 15,16-epoxy system.…”

Three new terpenoids, ardisiacrispins G-I (1, 4 and 8), and eight known compounds, cyclamiretin A (2), psychotrianoside G (3), 3-hydroxy-β-damascone (5), megastigmane (6), corchoionol C (7), zingiberoside B (9), angelicoidenol (10), trans-linalool-3,6-oxide-β-D-glucopyranoside (11) were isolated from the roots of Ardisia crispa. The chemical structures of all isolated compounds were elucidated by extensive spectroscopic analyses, such as HR-ESI-MS, 1D and 2D NMR spectra. Ardisiacrispin G (1) represents the oleanolic-type scaffold featuring a rare 15,16-epoxy system. All compounds were evaluated for the cytotoxicity against two cancer cell lines (U87 MG and HepG2) in vitro. Compounds 1, 8 and 9 exhibited moderate cytotoxic activity with IC 50 values ranging from 7.6 � 1.1 to 28.8 � 3.2 μM.
