The pollution of organic dyes such as malachite green is one of the globally critical issues, calling for efficient mitigation methods. woodsonii plant and result indicated high polarity solvent (methanol and water) recovered higher bioactive compounds. In short, sequential extraction provides understanding of polarity specificity of C. Overall, methanolic extracts showed the significantly (p ≤ 0.05) highest ascorbic acid content (75.76☑.47 mg/100mL), total phenolic content (249.64☒.83 mg GAE/100g), DPPH free radical scavenging activity (78.76☐.97 %), ferric reducing antioxidant power (22.55☐.96 mg TEAC/g), superoxide anion scavenging activity (46.60☑.57 %) and hydroxyl radical scavenging activity (50.35☐.96 %).
Phytochemical screening showed positive presence of flavonoids (all types of extracts), terpenoids (only in methanolic extract) and tannins (except aqueous extract). woodsonii bract, at increasing polarities. Solvents of different polarities (hexane, ethyl acetate, methanol and water) were used to sequentially extract the C. The current study reports the composition, phytochemical and antioxidant properties of red button ginger (Costus woodsonii) using sequential extraction. (1904-1963), curator of the Missouri Botanical Garden Herbarium.Costus plant is considered as a medicinal plant especially in therapeutic intervention. The specific epithet 'woodsonii' honours Dr. Feed once a month with a balanced fertilizer such as one with a NPK ratio of 15-15-15. It grows best in rich, moist soil in semi-shade, being susceptible to sunburn under hot afternoon sun. The ants do not pollinate the tubular flowers, but they may help to protect the developing fruits from damage by fly larvae. It is woody and approximately round to egg-shaped.Īnts are attracted to the extrafloral nectaries which occur between the bracts and supply nectar. The dry, dehiscent fruit is known as a capsule. They emerge at the top of the inflorescence, 1-3 at a time from between the bracts. The reddish-orange, tubular flowers have a yellow-orange lip near the apex. The bracts are tightly overlapped, bright red and waxy. The inflorescence is cylindrical with a tapered tip (6-10 cm long) and occurs at the stem tip.
The aboveground stems are erect to leaning and loosely spiraled. Round, succulent stems are produced by an underground horizontal stem known as a rhizome. The broadly elliptical leaves (15 cm long, 8 cm wide) are hairless, glossy and spirally arranged along the stems. It is a perennial herbaceous plant about 1-2 m tall, with a clump forming growth habit.
