Three new kinds of phenylethyl chromone derivatives, named AH1A, AH2a and AH2b, were isolated from the crude AH1 (agarotetrol) and AH2 (isoagarotetrol) fractions of agalwood (Jinko)from Kalimantan. AH<1A> separated from the crude AH1 fraction through the process of acetylation was characterized as 2-[2-(4-methoxyphenyl)ethyl]-5α, 6β, 7β, 8α-tetraacetoxy-5, 6, 7, 8-tetrahydro-chromone, and AH2a and AH<2b>, from crude AH2 fraction, were established to be 2[2-(4-methoxyphenyl)ethyl]- and 2-[2-(2-hydroxyphenyl)ethyl]-5α, 6β, 7α, 8β-tetrahydroxy-5, 6, 7, 8-tetrahydrochromone, respectively.
