Leaves of Tabebuia bahamensis, collected on Abaco Island, Bahamas, were dried and extracted with dichloromethane to yield a crude extract. Using preparative flash column chromatography on silica gel, enabled the isolation of ursolic acid with an excellent yield of 2.06 percent based on the mass of dry leaves. Both the crude leaf extract and ursolic acid produced selective in-vitro cytotoxic act...
متن کاملFour New Dicaffeoylquinic Acid Derivatives from Glasswort (Salicornia herbacea L.) and Their Antioxidative Activity.
Four new dicaffeoylquinic acid derivatives and two known 3-caffeoylquinic acid derivatives were isolated from methanol extracts using the aerial parts of Salicornia herbacea. The four new dicaffeoylquinic acid derivatives were established as 3-caffeoyl-5-dihydrocaffeoylquinic acid, 3-caffeoyl-5-dihydrocaffeoylquinic acid methyl ester, 3-caffeoyl-4-dihydrocaffeoylquinic acid methyl ester, and 3,...
متن کاملDistribution of Particles Which Produces a “Smart” Material
If Aq (β, α, k) is the scattering amplitude, corresponding to a potential q ∈ L2(D), where D ⊂ R3 is a bounded domain, and eikα·x is the incident plane wave, then we call the radiation pattern the function A(β) := Aq (β, α, k), where the unit vector α, the incident direction, is fixed, β is the unit vector in the direction of the scattered wave, and k > 0, the wavenumber, is fixed. It is shown ...
متن کاملAcylphloroglucinol Derivatives from the South African Helichrysum niveum and Their Biological Activities.
Phytochemical investigation of aerial parts of Helichrysum niveum (H. niveum) using different chromatographic methods including semi-preparative HPLC afforded three new (1-3) and six known (4-10) acylphloroglucinols alongside a known dialcohol triterpene (11). The structures of the isolated compounds were characterized accordingly as 1-benzoyl-3 (3-methylbut-2-enylacetate)-phloroglucinol (helin...
متن کاملGenome sequence of Escherichia coli XH140A, which produces L-threonine.
Here we report the draft annotated genome sequence of Escherichia coli XH140A, which is used to produce l-threonine in industry. The genome sequence will allow the characterization of the molecular mechanisms underlying its beneficial properties.
