40] It has been reported that other phytoestrogens such as luteolin and apigenin were competitive with cytochrome p450 aromatase.
together with [beta]-sitosterol (2) [14], 6-hydroxy-7-methoxycoumarin (3) [15], ursolic acid (4) [16], epigenin (5), luteolin (6) [17] and [beta]-sitosterol 3-O-[beta]-D-glucopyarnoside (7) [18] from the methanolic extract of the aerial parts of C.
Luteolin, an abundant dietary component is a potent anti-leishmanial agent that acts by inducing topoisomerase II-mediated kinetoplast DNA cleavage leading to apoptosis.
Materials and methods: ELISA tests and real-time PCR analysis were used to assess the expression of MUC1 mucin in fibroblast cells cocultured with 30 [micro]M concentration of luteolin.
Thus, we designed the present study to collect data on the concentration-response relation between the protective and cytotoxic effects of luteolin on human MG-63 osteoblastlike cells under high-glucose versus normalglucose states to distinguish between luteolin cytoprotective and cytotoxic concentration ranges.

The flavonoids diosmetin, genkwanin, luteolin, hispidulin and apigenin; caffeic, chlorogenic and rosmarinic acids; and terpenes--carnosol, rosmanol, epirosmanol, isorosmanol, rosmarini difenol, rosmariquinone and rosmadiol have been registered as chemical components of rosemary leaves (Ramalho and Jorge, 2006).
Steam distilled carrot seed oil typically contains significant amounts of the sesquiterpene alcohol carotol (<67%) and the monoterpenoid ester geranyl acetate (<25%) (Figure 3), with highly variable amounts of the monoterpenoids alpha-pinene (2-25%), sabinene (<32%) and linalool (<6%), and of the sesquiterpenoids P-bisabolene (<16%) and daucol (<10%) (13,14,15,16) Three flavones, luteolin, luteolin 3'-O-P-D-glucopyranoside and luteolin 4'-O-P-D-glucopyranoside have been isolated from a methanol extract of carrot seed.
It is worth mentioning that, the findings of present study are supported by the isolation of eriodictyol, luteolin, kaempferol, quercetin, anastatin A and B, silybin A, isosilybins A and B, hierochins A and B, (2R,3S)-2,3-dihydro-2-(3,4-dimethoxyphenyl)-3-hydroxymethyl-5-(2- formylvinyl)-7-hydroxy benzo furan, (+)-dehydro- diconiferyl alcohol, (+)-balanophonin, 1-(4-hydroxy-3-methoxyphenyl)-2-{4-[(E)-3-hydroxy-1-propenyl]-2-methoxyphenoxy}-1,3-propanediol, and 3,4-dihydroxybenz- aldehyde, form A.
Fraction EaII was found to contain coumestan wedelolactone and demethylwedelolactone as major components with apigenin, luteolin, 4-hydroxybenzoic acid, and protocatechuic acid as minor constituents [44].
