dc.description.abstract | Objective(s): In food industry, the inhibition of tyrosinase is very important, because this enzyme
catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones,
which contribute in undesirable color and taste of fruits and vegetables. Teucrium polium L. var.
gnaphalodes (Lamiaceae), a wild-growing flowering plant that has many applications in food
preparations and traditional medicine. In Persian language, this medicinal herb is called
Kalpoureh.
Materials and Methods: 1D- and 2D-NMR experiments were used to determine the chemical
structures of the isolated compounds. Antioxidant and tyrosinase inhibitory activities of the
isolated compounds were evaluated using DPPH, FRAP and mushroom tyrosinase inhibition
assays.
Results: In this research, we isolated two phenylpropanoid glycosides including verbascoside and
poliumoside and two flavonoids including jaranol and isorhoifolin using chromatographic
techniques. We found promising antioxidant and anti-tyrosinase compounds from Teucrium
polium L. var. gnaphalodes.
Conclusion: To date, different compounds have been isolated and characterized from T. polium
including terpenoids and flavonoids. But no phytochemical study has been reported from
T. polium var. gnaphalodes. Poliumoside and jaranol showed promising antioxidant and
tyrosinase inhibitory activities, respectively | |
