Proanthocyanidins isolated from the leaves of evaluated on the activities of rumen enzymes: and studies.

Two new proanthocyanidins (2S:3S)-(-)-epicatechin-(4α→8)4-(2R:3R)-(+)-catechin (Compound 1) and (2R, 3R)-3-O-galloyl-(+)-catechin (4β→8)3-(2R, 3R)-3-O-galloyl-(+)-catechin (Compound 2) were isolated from and characterized by ultraviolet spectroscopy (UV), proton nuclear magnetic resonance (H NMR), C NMR, and heteronuclear multiple bond correlation . The bioactivity and drug scores of isolated compounds were predicted using OSIRIS property explorer applications with drug scores of 0.03 (compound 1) and 0.

Nutrient and Rumen Fermentation Studies of Indian Pasture Legumes for Sustainable Animal Feed Utilisation in Semiarid Areas.

This study evaluated 5 annual and 11 perennial Indian pasture legumes species for their nutritive value, dry matter and mineral contents and in vitro fermentation parameters. Legume species differed significantly ( < 0.05) in various nutritional aspects such as organic matter, crude protein (CP), ether extract, fibres and protein fractions.

Proanthocyanidins Modulate Rumen Enzyme Activities and Protein Utilization In Vitro.

This study investigated the principal leaf protein (rubisco) solubilization and in vitro ruminal enzyme activity in relation to the molecular structure of proanthocyanidins extracted from leaves of Anogeissus pendula and Eugenia jambolana. Six proanthocyanidin fractions were extracted by 50% (v/v) methanol−water followed by 70% (v/v) acetone−water and then distilled water from leaves of A. pendula (AP) and E.

Sequential Extraction of Proanthocyanidin Fractions from Species and Their Effects on Rumen Enzyme Activities In Vitro.

Three proanthocyanidin fractions per species were sequentially extracted by 50% (v/v) methanol−water, 70% (v/v) acetone−water, and distilled water from leaves of Ficus racemosa (fractions FR) and F. religiosa (fractions FRL) to yield fractions FR-50, FR-70, FR-DW, FRL-50, FRL-70, and FRL-DW. Fractions were examined for their molecular structure, effect on ruminal enzyme activities, and principal leaf protein (Rubisco) solubilization in vitro.

Effect of Trimeric Myricetin Rhamnoside (TMR) in Carrageenan-induced Inflammation and Caecal Ligation and Puncture-induced Lung Oxidative Stress in Mice.

The Eugenia jambolana is used in folklore medicine. Leaves of E. jambolana contain flavonoids as their active constituents which possess in vitro antiinflammatory, antioxidant and the antimicrobial activity.

Analgesic activity of Eugenia jambolana leave constituent: a dikaempferol rhamnopyranoside from ethyl acetate soluble fraction.

Context: Eugenia jambolana Lam. (Myrtaceae) is a medicinal plant used in folk medicine for the treatment of diabetes, inflammation, and pain.

Objective: We investigated the antinociceptive effect of kaempferol-7-O-α-l-rhamnopyranoside]- 4'-O-4'-[kaempferol-7-O-α-l-rhamnopyranoside (EJ-01), isolated from the E.

Neuroprotective effect of 5,7,3',4',5'-pentahydroxy dihydroflavanol-3-O-(2''-O-galloyl)-beta-D-glucopyranoside, a polyphenolic compound in focal cerebral ischemia in rat.

Ischemia/reperfusion injury ends up in the cascade of excitotoxic stimulation of superoxide and nitric oxide formation leading to the generation of highly reactive products, including peroxinitrite and hydroxyl radical, which are capable of damaging lipids, proteins and DNA. Several polyphenolic compounds scavenge the radicals and protect from injury. 5,7,3',4',5'-pentahydroxy dihdroflavanol-3-O-(2''-O-galloyl)-beta-d-glucopyranoside (AP1), a polyphenolic compound, isolated from Anogeissus pendula Edgew was tested for its neuroprotective effect in transient focal cerebral ischemia in rats.
