Evaluation of nutritional, anti-nutritional and some biochemical studies on Pleurotus squarrosulus (Mont.) singer using rats

Abstract

Evaluation of nutritional, anti-nutritional and some biochemical studies on Pleurotus squarrosulus (Mont.) Singer using rats was undertaken with standard methods. Results of nutritional contents such as proximate composition revealed moisture (11.67%), crude protein (21.31%) and total carbohydrate (51.58%). Vitamin composition showed the presence of vitamins A (0.17 mg/kg), B2 (0.62 mg/kg), B3 (0.45 mg/kg), B6 (0.84 mg/kg), and D (0.82 mg/kg). Important minerals such as potassium (20.75 mg/100 g), calcium (41.14 mg/100 g), magnesium (0.70 mg/100 g), and iron (17.80 mg/100g) were found in the studied sample with nine essential amino acids. P. squarrosulus sample revealed sums of polyunsaturated fatty acid of 13.14% and saturated fatty acid of 86.85%. Result of anti-nutritional composition of P. squarrosulus showed the presence of saponins (5.11 mg/100 g), oxalate (0.28 mg/100 g), phytate (0.75 mg/100 g) among others. The anti-nutrient to mineral molar and mineral weight ratios of the studied sample were within the recommended critical values/ideal ratios for bioavailability. Amino acid groups positioned the studied sample as having more non-essential amino acids than essential ones; with total neutral amino acids being the highest while total sulphur-containing amino acid was the lowest. Results of biochemical studies implicated P. squarrosulus as a weight reducing recipe, which can lower cholesterol levels, influence haematological indices positively, and lower aspartate aminotransferase (AST) and alanine transaminase (ALT) liver enzymes. However, P. squarrosulus increased alkaline phosphatase (ALP) and lowered reproductive hormonal levels in test rats when compared to experimental control and those placed on reference foods. Since ALP increase is associated with the prostate, there is need to extend the study on P.squarrosulus to accommodate its effect on prostate and reproduction. This study has evaluated the nutritional, anti-nutritional and some biochemical studies on P.squarrosulus (Mont.) Singer using rats.

Variation in Body Weight, Lipid Profile and Selected Reproduction Hormones in Rats Given Psidium guajava Leaves from Crude Oil Polluted and Non-Crude Oil Polluted Areas

“…Luteinizing hormone (LH) is one the gonadotropins that stimulate the gonads both in testes of male and ovaries of female [39,40]. Luteinizing hormone stimulates the synthesis as well as the secretion of testosterone with the help of its receptors that bind to leydig cells [40,41].…”

Effect of ethanolic leaf extract of Vinca major L. on biochemical parameters and glucose level of alloxan induced diabetic rats

“…Assessment of haematological parameters can be used to determine the extent of deleterious effect of foreign compounds in the body (Mohammed et al, 2009;Duru et al, 2012b;Duru et al, 2018). Both plant extracts and free radical from alloxan, on the blood constituents of an animal are amongst the foreign compounds (Mohammed et al, 2009).…”

“…Such plants are known as medicinal plants and are the main source of organic compounds such as polyphenols, tannins, alkaloids, carbohydrates, terpenoids, steroids, flavonoids and etcetera (Marles and Farnsworth, 1995). These compounds are collectively addressed as phytochemicals (Marles and Farnsworth, 1995;Amadi et al, 2012;Duru et al, 2018) and represent a source for the discovery and development of new types of antidiabetic molecules (Firdous, 2014). Nawrot et al (2003) and Agomuo et al, (2017) noted that natural compounds found in plants or their synthetic forms are the basis of modern pharmacopeia.…”

Comparative Study on Effect of Chrysophyllum albidum Medicinal Plant from Crude Oil Polluted and Non-crude Oil Polluted Areas on Selected Biochemical Parameters in Rats

“…Different authors have reported evaluations on medicinal plants and their products in relation to the body [5][6][7][8][9]. Different studies have authenticated the potency of so many medicinal plants against different disease conditions [1,3,[10][11][12][13][14][15][16][17][18][19][20]. It has been reported that natural compounds found in plants or their synthetic forms are the basis of modern pharmacopeia [21][22].…”
