Proximate Composition, Free Radical Scavenging and NOS Activation Properties of Ramaria aurea

Abstract: Mushrooms are a high valued source of nutrition and mineral constituents which are of paramount importance in the present age. Here, different nutritional parameters, i.e., protein, carbohydrate, fat, amino acid, crude fiber and mineral contents of Ramaria aurea were evaluated. Results showed that this mushroom had significant amount of carbohydrate, protein, free amino acids and crude fiber where as low amount of fat signifies its importance as diet for the sufferers of diabetes, obesity, atherosclerosis, high blood pressure, etc. Mineral analyses showed that this mushroom was good source of calcium, magnesium, potassium, phosphorous and iron. Cellular damage caused by reactive oxygen species has been implicated in several diseases and hence antioxidants have significant importance in human health. The cold water, hot water and ethanolic extract of Ramaria aurea were analyzed for their antioxidant activities in different systems namely inhibition of lipid peroxidation, DPPH free radical and hydroxyl radical scavenging activities. The antioxidant activities among the three different extracts, ethanolic extract showed the strongest antioxidant activities in all the test systems. Furthermore, crude, boiled and ethanolic extracts also increased significantly nitric oxide production (319.1, 383.4 and 605.8 pmol NO produced/mg dry wt/h respectively) over the control. The present results revealed that this mushroom might be utilized as a promising dietary supplement.

In Vitro Protective Ability of Ramaria aurea Against Free Radical and Identification of Main Phenolic Acids by HPLC

Abstract: Free radical scavenging activity of Ramaria aurea, an edible mushroom, naturally grown in Shilong, India, was evaluated. A heat-stable, polyphenol-rich extract (RauPre) was prepared from the dried basidiocarps and analyzed. The major chemical constituent of RauPre was phenols (26.86 μg gallic acid equivalents [GAE] mg−1 of dry extract); flavonoids, β-carotene, lycopene, and ascorbic acid were present in minor amounts. Main phenolic acids identified by high performance liquid chromatography (HPLC) were caffeic acid > cinnamic acid > gallic acid. Results from antioxidant assays demonstrated potential for superoxide and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (EC50 0.283 mg mL−1 and 0.384 mg mL−1, respectively). RauPre chelated ferrous ion (EC50 0.95 mg mL−1) and had Fe3+ to Fe2+ reducing power (EC50 1.025 mg mL−1). The activity of 1 mg of RauPre was equivalent to 86.7 μg ascorbic acid for total antioxidant capacity.

2-Methoxy-3,4-Dihydroxybenzoic Acid and other Compounds from Ramaria aurea AND Clavariadelphus ligula

Abstract: Ramaria aurea (Schaeff.) Quel. and Clavariadelphus ligula (Schaeff.) Donk. are fungal species of the family Gomphaceae and representatives of the class Agaricomycetes that are widely distributed over Siberia and the Russian Far East. Young fruiting bodies of both species are used as food because of the high gustatory qualities. Information on the chemical components and biological activity of R. aurea and C. ligula has not been published. Preliminary investigations found that extracts of these fungi possessed cytotoxic and antiradical activity. The goal of the present work was to study the chemistry of R. aurea and C. ligula fruiting bodies. Fruiting bodies of these plants were collected in the vicinity of Pykhta Gap (Zaigraev District, Republic of Buryatiya,
