Evaluation of Bioactive Compounds and Antioxidant Potential of Hydroethanolic Extract of Lam. from Rajasthan, India

Lam., the miracle tree, is widely used as a traditional medicine. The analyses of phytochemicals and antioxidant potential of hydroethanolic extract of various plant parts of revealed that leaves possessed the highest content of total phenolics (9.58 mg/g), β-carotene (14.10 mg/g) and lycopene (2.60 mg/g). Flowers and bark showed the highest content of total flavonoids (3.5 mg/g) and anthocyanin (52.80 mg/g), respectively. Leaves also showed maximum antioxidant potential using nitric oxide scavenging assay (IC - 120 µg/ml) and deoxyribose degradation assay (IC-178 µg/ml). Highest DPPH radical scavenging activity was observed in flowers (IC-405 µg/ml). The GC-MS study revealed the presence of 29, 36 and 24 compounds in bark, leaf and flower, respectively. The major constituent identified were epiglobulol (41.68% in bark), phytol (23.54% in leaf) and -sitosterol (15.35% in flower).The phytochemicals identified possess several therapeutic activity, including antioxidant potential, which was confirmed through earlier reports. Moreover, the presence of 1,1,3-triethoxubutane in all the plant parts analyzed, projects it as an important source of waste water treatment as hydrophobic modifiers.
