The aim of this study was the isolation and structural elucidation of steroidal glycosides from the underground parts of ramson Allium ursinum L. The structures of the isolated compounds were established based upon chromatographic methods and 1D- and 2D-NMR, MS and IR analyses. The mixture of two steroidal saponins: (25R)-spirost-5-en-3b-ol tetrasaccharide and (25R)-spirost-5, 25(27)-dien-3b-ol...

Thiosulfinates (TSs) have been implicated as a principle source of the antiplatelet property of raw onion and garlic juice. The in vitro responses of human platelets to dosages of four TSs were measured using whole blood aggregometry and compared by regression analysis. Of the compounds evaluated, methyl methane-TS (MMTS), propyl propane-TS (PPTS), and 2-propenyl 2-propene-TS (allicin) are pres...

Allium hirtifolim (Persian Shallot) belongs to Allium genus (Alliaceae family). We investigated the in vitro effects of chloroformic extract of A. hirtifolium and its Allicin on the proliferation of HeLa (cervical cancer), MCF7 (human, caucasion, breast, adenocarcinoma) and L929 (mouse, C3H/An, connective) cell lines. Our results showed that components of A. hirtifolium might inhibit proliferat...

The effect of boron on the mitotic index of Allium cepa root meristematic cells were investigated. By using the growth inhibition test LD50 value was determined first and then different doses of varied concentrations of boron were introduced to onion tuber roots. Distilled water was used as control. Since Allium cepa cell cycle is 24 hours, application process was carried out at 12, 24 and 48 h...

Illicium verum (badiane or star anise), Crataegus oxyacantha ssp monogyna (hawthorn) and Allium cepa (onion), have traditionnally been used as medicinal plants in Algeria. This study showed that the outer layer of onion is rich in flavonols with contents of 103 ± 7.90 µg/g DW (red variety) and 17.3 ± 0.69 µg/gDW (white variety). We also determined flavonols contents of 14.3 ± 0.21 µg/g 1.65 ± 0...

Growing vegetables economically in the use of constructed wetland for wastewater treatment can play a role in overcoming water and food scarcity. Allium porrum L., Solanum melongena L., Ipomoea aquatica Forsk., and Capsicum annuum L. plants were selected to grow in hybrid constructed wetland (CW) under natural conditions. The impact of the ratio of nitrate to ammonium nitrogen on ammonium and n...

conclusions this study showed that aqueous allium cepa and ixora brachiata root extracts as natural products could be used as alternative drugs in treatment of leishmaniasis. results among tested plant extracts, ixora brachiata root extracts revealed the best activity against leishmania major promastigotes with ic100 value of 2.5 mg/ml and ic50 value of 0.078 mg/ml. patients and methods the par...
