Antioxidant activity of green tea and halloysite nanotube formation

Abstract

Nanomaterials called Halloysite Nanotubes (HNTs) are distinctive and adaptable. There are numerous uses for these nanotubes in cancer treatment and sustained
drug delivery. Catechins, which make up as much as 30% of the dry weight of the leaf in green tea, are abundant. Catechins have antioxidant, anti-mutagenic, and
anticarcinogenic effects:DPPH assay and H2O2 assay was used to test the antioxidant activity of biogenic synthesized green tea extract. The antioxidant potential
of the plant extract depends on the presence of phenolic compounds and flavonoid. aqueous green tea extract from Hallo NF, which showed antioxidant efficacy
in the DPPH and H202 assays. From our results we have concluded that aqueous green tea extract from Hallo NF, which showed antioxidant efficacy in the DPPH
and H202 assays. Aqueous extracts showed higher antioxidant activity, which was correlated to high levels of phenolic compounds. With their hydroxyl groups,
polyphenols are essential for scavenging free radicals, antioxidation, and other pharmacological processes.
