%T The Tyrosinase and Cyclooxygenase Inhibitory Activities and Cytotoxicity Screening of Tamarindus indica Seeds
%V 73
%X The methanolic extracts from seeds of tamarind
(Tamarindus indica) was prepared by Soxhlet apparatus extraction
and evaluated for total phenolic content by Folin-Ciocalteu method.
Then, methanolic extract was screened biological activities (In vitro)
for anti-melanogenic activity by tyrosinase inhibition test, antiinflammation
activity by cyclooxygenase 1 (COX-1) and
cyclooxygenase 2 (COX-2) inhibition test, and cytotoxic screening
test with Vero cells. The results showed that total phenolic content,
which contained in extract, was contained 27.72 mg of gallic acid
equivalent per g of dry weight. The ability to inhibit tyrosinase
enzyme, which exerted by Tamarind seed extracts (1 mg/ml) was
52.13 ± 0.42 %. The extract was not possessed inhibitory effect to
COX-1 and COX-2 enzymes and cytotoxic effect to Vero cells. The
finding is concludes that tested seed extract was possessed
antimelanogenic activity with non-toxic effects. However, there was
not exhibited anti-inflammatory activity. Further studies include the
use of advance biological models to confirm this biological activity,
as well as, the isolation and characterization of the purified
compounds that it was contained.
