Diphenylamine has been isolated as one of the active antihyperglycemic agents of onion. It was identified by ir, uv, cmr, pmr, and mass spectra. It attained the highest percentage in mature onion bulbs; other onion organs contained diphenylamine in lower percentages. Green and black teas were found to contain relatively high percentages of diphenylamine, being higher in the former. Cooking was found to decrease the diphenylamine content.

Column chromatography of the dichloromethane fraction from an aqueous methanolic extract of fruit peel of Citrus pyriformis Hassk. (Rutaceae) resulted in the isolation of seven compounds including one coumarin (citropten), two limonoids (limonin and deacetylnomilin), and four sterols (stigmasterol, ergosterol, sitosteryl-3-β-D-glucoside, and sitosteryl-6-O-acyl-3-β-D-glucoside). From the ethyl acetate fraction naringin, hesperidin, and neohesperidin were isolated. The dichloromethane extract of the defatted seeds contained three additional compounds, nomilin, ichangin, and cholesterol. The isolated compounds were identifi ed by MS (EI, CI, and ESI), 1 H, 13C, and 2D-NMR spectral data. The limonoids were determined qualitatively by LC-ESI/MS resulting in the identifi cation of 11 limonoid aglycones. The total methanolic extract of the peel and the petroleum ether, dichloromethane, and ethyl acetate fractions were screened for their antioxidant and anti-infl ammatory activities. The ethyl acetate fraction exhibited a signifi cant scavenging activity for DPPH · free radicals (IC 50

The macro and micromorphology of the leaf, stem, flower, root and rhizome of Artemisia vulgaris L. are presented with the aim of finding their diagnostic characters by which the plant can be easily identified in both the entire and powdered form. INTRODUCTION Artemisia vulgaris L. (Mugwort) is an aromatic perennial herb, distributed worldwide. It is mostly native to temperate North America, Europe, some in South America and North Africa to Siberia. Three Artemisia species (A. judaica L., A. scoparia Waldst. & Kit. And A. monosperma Del.) were listed and recorded in flora of Egypt. Moreover, two more species (A.vulgaris L. and A. verlotiorum Lamotte.) were newly added to Genus Artemisia (Boulos, 2002). Phytochemical studies of Artemisia vulgaris L. resulted in the isolation of sterols, triterpenes and flavonoids. Biological screening of total ethanolic extract of the aerial parts of the plant proved antibacterial (Singh et al., 2002; Sura et al., 2012), antifungal, analgesic, antiinflammatory and anticancer activities especially colon carcinoma (Rabe et al., 2002). In Iran the leaf anatomy of different Artemisia species was studied and the results showed that Leaf symmetry is very variable and the dorsiventral structure was only seen in A. vulgaris (Noorbakhsh et al., 2008). The literature review showed no reports concerning the macro-and micromorphology of the wild plant growing in Egypt. The present work covers macroand micromorphological study of the leaves, stem, flowers, rhizome and root with the aim of finding out the diagnostic features by which the plant can be easily identified in both entire and powdered forms. MATERIALS AND MATHODS Plant material Flowering and fruiting plant of Artemisia vulgaris L. was collected in the flowering and early fruiting stage on May 2013 from the plant growing wild in the irrigated canal bank, El-Qanater, Qalubiya, Egypt. The identity was kindly verified by Prof.
