Supplementary Material

A complete description of the entire extraction process and identified compounds is shown. Briefly, dried ground bark of Chisocheton tomentosus (3.5 kg) was defatted with hexane and dichloromethane for five days. The crude extract was evaporated using a rotary evaporator. The extract (10.0g) was subjected to a silica gel column and eluted gradiently using hexane:DCM and DCM:acetone. Fraction 5 of DCM:acetone (60:40) was further subjected to an isocratic separation using silica gel column with acetone:DCM:hexane (25:25:50). A colorless crystal (0.2 g) of fraction 3 was obtained from the isocratic separation.
