Some constituents of hops

Lupulon and Humulon-antibiotic Constituents of Hops.

Some Constituents of Elementary Bodies of Vaccinia

Treatment of elementary bodies of vaccinia with dilute solutions of sodium hydroxide resulted in the extraction of certain soluble materials accounting for half of the dry weight of the virus. Elementary bodies contained about 0.4 per cent inorganic phosphorus, practically all of which occurred in the form of a nucleoprotein containing thymus nucleic acid. In addition, a substance was recovered...

Phytochemical constituents of some Indian medicinal plants

Alkaloids, tannins, saponins, steroid, terpenoid, flavonoids, phlobatannin and cardie glycoside distribution in seven medicinal plants belonging to different families were assessed and compared. The medicinal plants investigated were Aegle marmelos, Cynodon dactylon, Eclipta prostrata, Moringa pterygosperma, Pongamia pinnata, Sida acuta and Tridax procumbens. The significance of the plants in t...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Study of Some Chemical Constituents and Antioxidant Activity of Beau

Beaumontia grandiflora Wall. (Apocynaceae) is an ornamental plant cultivated in Egypt. Investigation of the chemical constituents of the aerial parts of B. grandiflora Wall. in pet. ether extract led to isolation and identification of twelve fatty acids in which linoleic acid (29.60%) and Palmitic acid (19.12%) are the main acids. The unsaponifiable fraction was found to contain a series 14 27 ...
