[Isolation and preparation of gallic acid from Terminalia chebula Retz. with high-speed counter-current chromatography].
A separation method based on high-speed counter-current chromatography (HSCCC) has been established for the isolation and preparation of gallic acid from the ethanol extract of Terminalia chebula Retz. After comparing five kinds of solvent protocols of HSCCC, the two-phase system of n-hexane-ethyl acetate-methanol-water (1:5:1:5, v/v/v/v) was finally chosen as the operating solvent of HSCCC for...
متن کاملGallic Acid Production with Mouldy Polyurethane Particles Obtained from Solid State Culture of Aspergillus niger GH1.
Gallic acid production in a batch bioreactor was evaluated using as catalytic material the mouldy polyurethane solids (MPS) obtained from a solid-state fermentation (SSF) bioprocess carried out for tannase production by Aspergillus niger GH1 on polyurethane foam powder (PUF) with 5 % (v/w) of tannic acid as inducer. Fungal biomass, tannic acid consumption and tannase production were kinetically...
متن کاملAntimicrobial activity of Terminalia chebula
Terminalia chebula is a popular medicinal plant according to Ayurveda for its broad spectrum medicinal value including in the treatment of enteric disorders. Leaf extracts in water as well as in various organic solvents (namely methanol, ethanol, ethyl acetate and chloroform) were analyzed to testify its antibacterial activities against four different bacteria causing enteric disorders, viz.

متن کاملAnti-Hyperglycemic Effect of Chebulagic Acid from the Fruits of Terminalia chebula Retz
In the present study, we firstly compared rat intestinal α-glucosidase inhibitory activity by different ethanol-aqueous extractions from the dried fruits of Terminalia chebula Retz. The enzymatic assay showed that the 80% ethanol extract was more potent against maltase activity than both 50% and 100% ethanol extracts. By HPLC analysis, it was determined that the 80% ethanol extract had a higher...
