the antioxidant activities of methanol (me), ethanol (ee), water (we) and ethyl acetate (eae) extracts of four inula helenium l. taxa (i. helenium ssp. orygalis (boiss.) grierson, i. helenium ssp. pseudohelenium grierson, i. helenium ssp. turcarasemosa grierson and i. helenium ssp. vanensis grierson) were investigated. the phosphomolybdenum assay, β-carotene–linoleate bleaching and dpph radical...

BACKGROUND The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE). METHODS The anti-inflammatory effects of IFE against nitric oxide (NO), PGE(2), TNF-α, and IL-6 release, as well as NF-κB and MAP kinase activation wer...

We have identified through bioassay guided isolation an allelochemical, eudesmane-type sesquiterpeniod, 3beta-caffeoxyl-beta1,8alpha-dihydroxyeudesm-4(15)-ene (1), from an endemic plant species growing in the Himalayas. In our search for the bioactive subfraction, the hexane one was highly significant, showing 100% inhibition of lettuce seed growth at 100 ppm while other subfractions (chlorofor...

The retinal structures of the compound eyes of insects are being investigated as par t of a comparative study of the s tructure and biochemistry of visual organs (1 5). T he compound eye of the insect is composed of numerous ommatidia , each of which consists of f rom four to eight re t inula cells. Each re t inula cell contains a differentiated structure, the rhabdomere , a photoreceptor . The...
