Abstract
Dihydroquinol derivative 1, quinol glucopyranoside 2 and quinol derivative 3 have been isolated from the ethyl acetate soluble fraction of Ajuga parvi flora and their structures have been elucidated through spectroscopic studi es as methyl 2-[2,2-dimethyl-6-oxo-7-dihydro-1,3-benzodioxol-3(6H)-yl]aceat e (1), 2-hydroxy-4 beta -methyl-4 alpha-(beta -D-glucopyranoside)-2,5-cyclo hexadien-1-one (2) and (4-oxo-2,5-cyclohexadien-1-yl) acetic acid (3). The known quinol 4 has also been isolated for the first time from this species.
