8-(3′,3′-Dimethylbutyl)-6-hydroxy-2,6,7,8-tetrahydropyrrolo[1,2-a]pyrimidin-3-one (1) and 5-isopentyl-4a,8a-dimethyldecahydronaphthalen-2-ol (2) have been isolated from the aerial part of Sida rhombifolia L. for the first time along with the previously reported stigmasterol. Their structures were established on the basis of spectral and chemical methods.
