چکیده
In the title mol-ecule {systematic name: (5S)-5-[(β-d-gluco-pyranos-yloxy)meth-yl]furan-2(5H)-one}, C(11)H(16)O(8), the five-membered ring is essentially planar, the maximum deviation being 0.0151 (13) Å for the O atom. The six-membered ring adopts a chair conformation with puckering parameters Q = 0.581 (2) Å, θ = 9.0 (2)° and ϕ = 39.7 (13)°, and with all of the substituents of the glucoside unit having normal equatorial orientations. The crystal structure is stabilized by extensive O-H⋯O and C-H⋯O hydrogen bonding, resulting in a three-dimensional network.

Secondary metabolites and insecticidal activity of Anemone pavonina.
The insecticidal properties of the crude extracts of the leaves and flowers of Anemone pavonina were evaluated on Pheidole pallidula ants and showed significant levels of activity. Bioassay-guided fractionations led to the isolation of the butenolide ranunculin (1) as the active principle. Chemical investigations of the extracts showed them to contain as major components the sitosterol glycopyr...

and is an endemic species in Korea. The roots of this plant have been widely used in traditional medicine for the treatment of several diseases, particular malaria and amoebic dysentery. This plant has been investigated extensively, resulting in the isolation of various saponins, ranunculin, anemonin, protoanemonin and triterpenes. Our continuing investigation of the chemical constituents of th...
متن کاملGains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
متن کاملImproved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.
BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...
