Objective: To access the anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe (OP) grade black tea with a view to develop an anti-aging skin formulation. Methods: Five concentrations (0.125, 0.250, 0.500, 1.000 and 2.000 mg/mL) of black tea brew (BTB) were made using a freeze dried sample of Sri Lankan low grown orthodox OP grade black tea which was prepared according to international organization for standardization specification. Epigallocatechin gallate (EGCG) was used as the reference agent (concentrations tested: 0.012, 0.025, 0.050, 0.100 and 0.200 mg/mL). Anti-hyaluronidase activity of BTB and EGCG in vitro were ascertained spectrometrically using hyaluronic acid (from rooster comb) and bovine testicular hyaluronidase. Results: The results revealed that BTB had moderate [IC50=(1.09±0.12) mg/mL] and dose dependent (r2=0.94) anti-hyaluronidase activity. EGCG also exhibited dose dependent (r2=0.93, P<0.05) anti-hyaluronidase activity which was superior [IC50=(0.09±0.00) mg/mL] to BTB. Conclusions: Sri Lankan low grown orthodox OP grade black tea has promising anti-hyaluronidase activity in vitro and has the potential to be used as an anti-aging cosmaceutical. In addition, it may prove useful as a beverage in the management of allergy, some joint diseases and envenomation.
