The approximate mineral and phytochemical content of the leaves, stem bark, and roots of Pterocarpus erinaceus in India

Abstract

Proximate analysis of dried Pterocarpus erinaceus leaves (DPE), stem bark (DSB) and root (DSR) contained moisture (9.11%, 7.61%, 7.02%), crude protein (7.60%, 5.11%, 4.33%), crude fibre (12.2%, 25.6%, 18.5%), ether extracts (0.58%, 0.42%, 0.30%), ash (12.6%, 10.5%, 10.2%) and carbohydrates (45.4%, 38.0%, 37.2%) respectively. Mineral composition of DPE revealed the presence of calcium (108.6 mg/100 g), phosphorus (60.38 mg/100 g), potassium (39.7 mg/100 g), magnesium (12.51 mg/100 g), zinc (10.44 mg/100 g), manganese (8.55 mg/100 g), cobalt (1.16 mg/100 g), copper (4.58 mg/100 g), sodium (25.2 mg/100 g) and iron (16.13 mg/100 g) while those of DSB and DSR contained calcium (90.60, 91.55 mg/100 g), phosphorus (40.11, 43.80 mg/100 g), potassium (30.2, 30.0 mg/100 g), magnesium (9.93, 8.90 mg/100 g), zinc (7.55, 7.00 mg/100 g), manganese (5.20, 4.88 mg/100 g), cobalt (1.11, 1.00 mg/100 g), copper (2.40, 2.21 mg/100 g), iron (19.6, 18.4 mg/100 g) and iron (11.0, 10.67 mg/100 g). The phytochemical analysis of DPE, DSB, and DSR revealed that it contains high levels of flavonoids (11.20, 7.51, 7.20 mg/g), tannins (8.81, 4.91, 4.10 mg/g), steroids (1.61, 1.14, 1.02 mg/g), glycosides (4.42, 1.20, 6.19 mg/g), phenols (41.5, 30.4, 31.2 mg/g), saponins (28.6, 15.1, 14.0 mg/g), alkaloids (19.6, 15.8, 25.3 mg/g), flavonoids (11.20, 7.51, 7.20 mg/g), tannins (8.81, 4.91, 4.10 mg/g), and terpenoids (1.40, 0.65, 0.55 mg/g), respectively. According to the findings, DPE, DSB, and DSR are rich in minerals and phytochemicals, and they can be utilized as a natural substitute for antibiotics in animal production.
