Abstract:The structure of the title compound, which was isolated fromClinopodium polycephalum (Vant.) by C. Y. Wu et Hsuan, has been determined byX-ray diffraction analysis. C11H16O3, Mr= 196. The crystal belongs to the monoclinicspace group P21 with a= 6. 072 (3), b=11. 682 (5), c= 7. 865 (4) A, β= 109. 61(4)°, V=525. 5(4) , Z= 2, F(000) =212, Dc= 1.234 g/cm3, μ=0.08 mm-1.The structure was solved by direct methods and refined to R=0. 048 for 616 observedreflections. The molecule is composed of a six-membered ring and a five-membered lactone ring with a methyl and a hydroxy group at the two asymmetrical carbons locatedon the same side of the nucleus.
Keywords:clinopodium polycephalum lolioide   crystal structure   antitumor activity
