ANTIOXIDANT ACTIVITY OF A NEW FLAVONE GLYCOSIDE FROM THE STEMS OF GMELINA ARBOREA ROXB.
AbstractGmelina arborea Roxb. belongs to the Verbenaceae family, commonly known as Gambhar. It is distributed throughout India, Ceylon, Malayan and Philippine Islands. Its roots have anthelmintic properties. Its flowers are useful in the treatment of leprosy and blood diseases. Its fruit has diuretic properties and aphrodisiac. It is also used in anemia leprosy and vaginal discharges. Leaves have shown analgesic, antimicrobial, and anti-diabetic activities. A new flavone glycosides 5, 7.4ʹ-trihydroxy-8, 3ʹ-dimethoxyflavone- 4ʹ-O-β-D-glucopyranosyl- 7-O-β-D-xylopyranosyl (1→2)-α-L-rhamnopyranoside(A) along with two known compounds Luteolin (B) and Apigenin (C) were isolated from ethanolic extract of the stem parts of the plant. The characterization and structural elucidation of these compounds were carried out by various color reactions, chemical degradation, and spectral analysis. Antioxidant activity of compound A was evaluated by 1, 1-diphenyl-2-pycrylhydrazyl (DPPH) assay system which has shown a significant radical scavenging activity.
