title: Isolation of antioxidant phytoconstituents from the seeds of Lens culinaris Medik.
abstract: Lens culinaris Medik (Leguminosae) is an annual, bushy and herbaceous plant cultivated globally for its edible seeds. A methanolic extract of the seeds contained four new antioxidant compounds, namely β-sitosteryl-3-(2'-n-eicosanyloxy)-benzoate (3), n-octadec-9-enoyl-1-β-D-glucurano-pyranoside (4) α-D-galactopyranosyl-(6 → 1')-α-D-galactopyranosyl-(6' → 1″)-α-D-galactopyranosyl-(6″ → 1‴)-α-d-galactopyranoside (5) and benzoyl-O-α-D-glucopyranosyl-(2a → 1b)-O-α-D-glucopyranosyl-(2b → 1c)-O-α-D-glucopyranosyl-(6c → 1d)-O-α-D-glucopyranosyl-(6d → 1e)-O-α-D-gluco-pyranoside (6) along with two known compounds n-heptadecanyl n-octadec-9-enoate (1) and β-sitosterol (2) on the basis of chromatographic and spectral data analytical techniques. Compound 3 showed significant antioxidant activity compared to compounds 4, 5, and 6.
