tuberosa leaves used in this work is highly pigmented and one of its main compounds is similar to hyperoside, a water-soluble compound. This may explain the better result obtained with ABTS in comparison with DPPH assay. The antioxidant properties of hyperoside have been demonstrated; for example...
Why is hexane known as a hydrocarbon? Why is methane a gas at room temperature? What is the reason why hydrocarbons are not soluble in water? Why are alkenes called unsaturated hydrocarbons? Why is the relative thermodynamic stability of isomeric organic compounds inferred from the heats of combu...

H2O2content and biochemical changes in Pinot Noir berries during development. A: Mean values of total acids (squares, expressed as grams of tartaric acid per liter) and sugars (triangles, expressed as total soluble solids in °Brix) of the must obtained from three clusters, at each time point...
After repeating the separating procedures with column- and preparative thin layer-chromatographies and assay, three antifungal sesquiterpenes were decided in the n-hexane soluble part of the methanol extract. Their structures were estimated to be 8-acetoxyelemol, 8-hydroxyelemol and hinokiic acid, ...
DMAP (m.p. 112-113°C) and PPY (m.p. 57-58°C) are colorless, crystalline substances which are very soluble in methanol, ethyl acetate, chloroform, methylene chloride, 1,2-dichloroethane, acetone, and acetic acid and less soluble in cold hexane, cyclohexane, and water. DMAP can be rec...
zone of 12 mm at a concentration of 100 mg/ml, whereas the aqueous extract only achieved an inhibition zone of 8mm. This discrepancy was attributed to the active ingredients present in the date seeds which could have been more soluble in ethanol than in water. Similar findings were obtained ...

We observed that incubation of isolated cell wall material and intact sacculi with acidified nitrite released 70–80% of GAC in a water-soluble form (Fig. 1b, d). In contrast, chemically N-acetylated GAS cell wall or sacculi were resistant to this treatment (Fig. 1b, d). Taken ...
