Antimicrobial and Cytotoxic Activity of Ethyl Acetate, Chloroform and N- Hexane Extracts of Cucumis Sativus Leaves
Plants are the important source of diverse range of bioactive principles. A large number of plants are constantly being screened for their possible medicinal value. The present study was designed to investigate the antimicrobial and cytotoxic activity of ethyl acetate (EAE), chloroform (CE) and n-hexane (HE) extracts of leaves of Cucumis sativus. Antimicrobial activity of EAE, CE and HE was tes...
متن کاملLocalization of Stem Elongation Control in Cucumis sativus L.
Reciprocal grafts, and applications of gibberellin (GA) and indoleacetic acid (IAA) were used to localize the site of control for stem elongation in cucumber (Cucumis sativus L.). Dwarf and tall plants were reciprocally grafted to determine influence of stems and roots on stem elongation. At 21 days there were no significant differences in length between stems grafted to their own roots and tho...
متن کاملAntimicrobial activity of sphingolipids isolated from the stems of cucumber (Cucumis sativus L.).
Three antimicrobial sphingolipids were separated by bioassay-guided isolation from the chloroform fraction of the crude methanol extract of cucumber (Cucumis sativus L.) stems and identified as (2S,3S,4R,10E)-2-[(2'R)-2-hydroxytetra-cosanoylamino]-1,3,4-octadecanetriol-10-ene (1), 1-O-β-D-glucopyranosyl(2S,3S,4R,10E)-2-[(2'R)-2-hydroxy-tetracosanoylamino]-1,3,4-octadecanetriol-10-ene (2) and so...
