Qualitative and quantitative evaluation of total flavonoids extracted from Mentha arvnesis aerial parts

الملخص EN

Mentha arvnesis is an important medicinal plant that contains many groups of secondary metabolites that have extensive biological activity.

The flavonoids were extracted from the aerial parts of the mature plant by using reflex extraction, and the aglycan fraction was isolated with ethyl acetate.

The flavonoids of the extract were detected qualitatively with TLC technique.

The total amount of flavonoids derived from the plant was estimated using a colorimetric method and the total value was calculated using the straight line equation of the standard flavonoid curve (Rutin).

The plant was found to be rich in flavonoids, especially rutin, quarrecetin, kaempferol, luteolin and low concentration of coumarin.

Total flavonoids were about 0.78 mg for each gm.
