Costus woodsonii was used as a green approach to synthesize zinc oxide (ZnO) nanoparticles from its bulb (flower). The use of biomass for functional nanomaterial is fascinating. 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. woodsonii is self compatible.Ĭostus plant is considered as a medicinal plant especially in therapeutic intervention. Set on self pollinated flowers, revealed that C. zeylonica are the main pollinators.Īutogamy, geitonogamy and xenogamy were carried out, to check whether the species is self compatible or not. Receptive at 06:00 and stigma loss its receptivity after 15:00. In vitro pollen germination is found maximum in 1% of sucrose solution. High percentages of pollen grains are fertile (89.7 ± 0.8%) Percentage of pollen viability is high at 07:00. Pollen grains are polyporate and remains as viable still after 13 hours after antherĭehiscence. Flowers offer both nectar and pollen to visitors. Occurs between 03:00 and 03:30 through longitudinal slit. Terminal, flowers emerge one at a time from bright red coloured bracts of inflorescence, flowers throughout the year.Īnthesis occurs between 05:00–06:00 and the average life span of individual flower is 1 day. Costus woodsonii is a perennial herb, belongs to the family Costaceae under the order Zingiberales.
