This means that your raw plant extract is a better antioxidant than your standard. Ii's OK.

Sundar Mety

your extract is good and better when comparing with standards

you may work more and further investigation particularly on that product also,

that investigation may give novels work for you project or ph.d work

Kebal Leila

this means that your extract has excellent antiradical power and this is very good. several articles have found that their extracts have shown results like yours. good luck
