Phytochemical and antioxidant profiling of Ocimum sanctum.

ABSTRACT: The leaves of Ocimum sanctum were extracted in methanol (OsM) and sequentially fractionated with n-hexane (OsH), ethylacetate (OsE) and butanol (OsB) to find the best extraction solvent for antioxidants from the herb known for its medicinal values. OsB was rich in both total polyphenolic content (TPC) (212.26 ± 6.3 mg GAE/g extract) and total flavonoid contents (TFC) (54.51 ± 3.5 mg QE/g extract). OsE also had significantly high TPC (202.71 ± 5.5 mg GAE/g extract). The EC₅₀ based on DPPH (3.91 ± 0.3 μg/ml), ABTS (1.6 ± 0.1 μg/ml) and phosphomolybdate (2.31 ± 0.1 μg/ml) for OsB; hydroxyl (5.3 ± 0.4 μg/ml), superoxide (7.32 ± 0.9 μg/ml) radicals for OsM and DPPH (8.61 ± 0.6 μg/ml), phosphomolybdate (2.43 ± 0.1 μg/ml) and ABTS (5.3 ± 0.4 μg/ml) for OsE were lower than ascorb
