Introduction

This research analyzed the antibacterial properties of C. Sinensis. The effectiveness is not specific to previously studied Staphylococcus aureus, but also to other bacteria on the skin such as Staphylococcus epidermidis. C. Sinensis extract can therefore potentially serve as a very important alternative to fighting acne and other infections with the added benefit that it could also be made into various products such as lotions, creams, and face masks.

Methods

This study starts with macerating dried green tea leaves with ethanol then rotary-evaporated to get the concentrated green tea leaf extract. Then the concentrated green tea leaf extract is being added with liquid nitrogen. Then the antibacterial testing was using a Well Difussion Assay. For the antioxidant test, test were carried out by DPPH scavenging Assays.

Conclusion

Through obtaining and analyzing the results, it can be concluded that the green tea leaf extract is indeed effective in its antibacterial and antioxidant properties. The extract showed a strong antioxidant activity and also its antibacterial properties is evident from the fact that it was able to inhibit the growth of both Staphylococcus aureus and Staphylococcus epidermidis.
