Crossflow filtration techniques (microand ultrafiltration), using inorganic membranes, were employed to clarify apple juice. Changes in the polyphenol composition (procyanidins, hydroxycinnamic derivatives, and dihydrochalcones) were monitored throughout the clarification process by means of a simple and reliable HPLC procedure. A factorial repeated measures design was constructed to ascertain ...

The effects of various inhibitors on crude, commercial and partially purified commercial mushroom tyrosinase were examined by comparing IC(50) values. Kojic acid, salicylhydroxamic acid, tropolone, methimazole, and ammonium tetrathiomolybdate had relatively similar IC(50) values for the crude, commercial and partially purified enzyme. 4-Hexylresorcinol seemed to have a somewhat higher IC(50) va...

Ethnomedicinal implies the usage of medicinal plants used by a group of people on account of their traditional knowledge and phytochemical means the individual chemical that plant contains. This review involves the ethnomedicinal and phytochemical perspectives of Pyrus communis Linn. In the “The Indian Materia Medica”, the common pear or gabbu gosha is considered as ‘Amritphale’ because of its ...

Myo-inositol, the precursor in the biosynthesis of inositol phospholipids and inositol phosphates, is found in many tissues at concentrations well above its concentration in the plasma, but the highest concentrations are in the central nervous system and the neuroretina. We describe an active, sodium gradient-dependent transport of myo-inositol into cultured endothelial cells derived from bovin...

Lycium barbarum L. polysaccharide (LBP) is prepared from Lycium barbarum L. (L. barbarum), which is a traditional Chinese medicine. LPB has been shown to have hypoglycemic effects. In order to gain some mechanistic insights on the hypoglycemic effects of LBP, we investigated the uptake of LBP and its effect on glucose absorption in the human intestinal epithelial cell line Caco2 cell. The uptak...

The specific binding of D-glucose to the isolated luminal cell membrane of the renal proximal tubule, the brush border, was studied. The initial interaction of D-glucose with this membrane was rapid; saturable; dependent on the concentrations of the sugar and the membrane; reversible; selectively influenced by the ionic environment; sensitive to temperature and pH ; inhibited by phloridzin, phl...
