Abstract

Six kinds of chromone derivatives, named AH1, AH2, AH3, AH4, AH5 and AH6, were isolated from agarwood (Jinko) from Kalimantan. Four constituents, AH3, AH4, AH6 and AH5, were characterized as 6-hydroxy-(I), 6-methoxy-(II) and 6, 7-dimethoxy-2-(2-phenylethyl) chromone (IV) and 6-methoxy-2-[2-(3-methoxyphenyl) ethyl] chromone (III), respectively.
