[31] reported a few compounds that have high antioxidant activity. The results indicated the major antioxidant components might not be flavonoids but might be those other bioactive groups, such as tannins, quinones, cardiac glycosides, saponins, terpenoids, and other phenolic compounds. The plant Justicia gendarussa was investigated for their antioxidant activity. The E60 extract showed the highest percentage inhibition at 1 mg/mL and the lowest IC50 [21]. Flavonoids with a hydroxyl moiety in the molecule play roles as proton donors and thus exhibit free radicalscavenging activity properties. dracaena For instance, lauric acid (n-dodecanoic acid) has 60% antioxidant activity in several food products, such as coconut and soybean products, myristic acid (tetradecanoid acid) has 71% antioxidant activity, and palmitic acid or (n-) hexadecanoid acid has 68% antioxidant activity. dracaena reflexa It is reduced to a stable diamagnetic molecule in the presence of an antioxidant molecule and changes colour from purple to yellow.

For example, Jerzykiewicz et al. Weight and percentage yield of crude extract of D. sanderiana. A high ethanol/water ratio extract does not necessarily contribute to high TFC. dracaena marginata dracena reflexa variegata fertilizzante It helps remove formaldehyde, benzene, trichloroethylene and carbon dioxide. The placement of several dracaena houseplants will increase humidity in the room. The data were analysed and compared with the reference of GC-MS library (National Institute of Standard and Technology). There are many Dracaena Marginata benefits and uses. This is because BHA is a pure synthetic antioxidant compound, whereas the plant extract contains mixtures of bioactive compounds. Moreover, underestimation of the TPC will occur since various types of phenolics react differently with the Folin-Ciocalteu reagent, particularly several phenolic compounds which exhibit low absorption [22]. Henry et al. A mixture of water and ethanol was used for extraction, as they offer low toxicity and high extraction yield. India's Largest Medicinal/Herbal Live Plants Online Store, Description: Live Healthy plant along with 5inches Diameter plastic pot plants height with pot is 1-3 feet Outdoor plant, keep it in full sunlight, watering daily Tree grows upto 20 feet, it has lots of medicinal value to remove toxins from human body ex L.
