Abstract
A high performance liquid chromatography (HPLC) method for the determination of the monosaccharide compositions and molar ratio of polysaccharide in quince has been established. The quince polysaccharides were derivatized with 1-phenyl-3-methyl-5- pyrazolone (PMP) after hydrolyzed into monosaccharides with 2 M sulfuric acid. Monosaccharide derivatives were separated by a reversed phase C18 column and monitored by UV at 250 nm. Analysis of monosaccharides of quince polysaccharides sample by HPLC indicated the presence of mannose, rhamnose, glucose, galactose, and arabinose with the molar ratio of 0.10, 0.72, 1.12, 4.23, and 4.73, respectively. It could be applied for the quality control of quince polysaccharides. Moreover, quince polysaccharide shows the inhibitory activity of protein tyrosine phosphatase- 1B (PTP1B) with IC50 value of 2.07 μg/mL.

Ayurvedic medicinal therapeutic approaches for inflammatory and neurodegenerative disorders
Usually, in our elderly population, neurodegenerative disorders occur due to neuron death. Alzheimer?s disease (AD) is an irreversible and progressive neurodegenerative disease. Dementia is the leading cause of AD, which affects about 30 million people worldwide. According to the World Alzheimer report 2018, a new case of dementia develops every ...read more
Recent Advances in Biotransformation of Bioactive Terpenoids using Aspergillus niger
Biotransformation is the reaction catalyzed by biological catalysts of either isolated enzymes or whole cell cultures of microorganisms. This process has been extensively applied in the conversion of bioactive terpenoids with high regio- and stereospecifity. This process has been also applied in the lead discovery and development. Aspergillus niger has ...read more
