Safety of (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol, is researched, Molecular C7H14O6, CAS is 1824-94-8, about Chemical composition and lipase inhibitory property of two varieties of guava fruits at different stages of ripening. Author is De Pradhan, Ipsita; De, Bratati.
The fruits of Psidium guajava L., known as guava, are edible. The objectives of the study were to analyze the chem. composition of the skin, flesh, and pulp of two different Indian varieties of guava, e.g., Khaja and Allahabad at different stages of ripening (immature green, mature green, color turning, ripe, and overripe), and to study the pancreatic lipase (PL) inhibitory properties of the fruit extracts In total, 86 compounds were identified from different parts of the fruits. The different parts varied chem. with different stages of ripening in two varieties of guava. Major components contributing to the variation were ascorbic acid, catechin, epicatechin, shikimic acid, quinic acid, and some polyols and amino acids. Ascorbic acid content increased in color turning, ripe, and overripe stages. All the parts inhibited PL, highest activity being shown by the skin extracts The two varieties were also different in PL inhibitory activities. Thus, the study highlighted the nutritional as well as PL inhibiting activity beneficial to prevent fat absorption.
