Candenatenins G-K, phenolic compounds from Dalbergia candenatensis heartwood
Five new phenolic compounds, designated candenatenins G-K (1-5), along with four known compounds, were isolated from the heartwood of Dalbergia candenatensis. The structures of these compounds were elucidated by HR-EI-MS, 1H and 13C NMR, COSY, HMQC, HMBC, and NOESY spectra. Compound 5 exhibited pote...

| Summary: | Five new phenolic compounds, designated candenatenins G-K (1-5), along with four known compounds, were isolated from the heartwood of Dalbergia candenatensis. The structures of these compounds were elucidated by HR-EI-MS, 1H and 13C NMR, COSY, HMQC, HMBC, and NOESY spectra. Compound 5 exhibited potent activity against DPPH radical scavenging with IC 50 value of 25.7 μM, whereas compound 2 showed cytotoxicity against NCI-H187 cell line with IC 50 value of 14.8 μM. © 2012 Phytochemical Society of Europe. |
