ABSTRACT
Objective To study the chemical constituents of agarwood from Aquilaria crassna. Methods The compounds were isolated and purified by various column chromatographic techniques. Their structures were identified on the basis of spectral data and physicochemical properties. And the compounds were tested for α-glucosidase inhibitory activity by pNPG method. Results One new sesquiterpenoid along with two known chromones, which were determined as methyl crassicid (1), 8-chloro-6-hydroxy-2-(2- phenethyl) chromen-4-one (2), 8-chloro-6-hydroxy-2-[2-(4-methoxyphenyl) ethyl] chromen-4-one (3), were obtained from the ethyl acetate extract obtained from 95% ethanol extract of agarwood from A. crassna. Conclusion Compound 1 is a new sesquiterpenoid named sesquiterpenoid, which exhibited α-glucosidase inhibitory activity with IC50 value of 121.8 μg/mL.
