Autor: Ding-Qing Wang, Rong-Hua Liu, Pu-Zhao Zhang, Shuai Lin, Feng Shao, Lan-Ying Chen, Huilian Huang

A new diaryl 1,2-diketone, named 1-(2,5-dihydroxy-4-methoxyphenyl)-2-phenylethane-1,2-dione (1), along with eight known compounds (2–9), were isolated from the heartwood of Dalbergia latifolia. They were identified on the basis of spectral data. Co
