ABSTRACT

The leaves of purple sweet potato (Ipomea batatas Poir) contain flavonoids, saponins and polyphenols, which exhibit the antibacterial activities. The purpose of this study is to formulate the prepared lotion from methanol extract of leaves of purple sweet potato, to test the quality of prepared lotion from the methanol extract of the samples according to the requirements and to determine the activity of the prepared lotion in inhibiting bacteria Staphylococcus aureus with concentration of 1.0%, 1.5% and 2.0%, respectively. The research proves that the leaves of purple sweet potato can be formulated as an antibacterial of prepared lotion and meet the requirements of quality test preparation lotions, including organoleptic test, pH test, and the scatter test. Antibacterial activity test was conducted using the well diffusion method and the effectiveness of antibacterial was examined according to the inhibition zone. The results showed that the methanol extract of lotion from the leaves of purple sweet potato inhibit the bacterial growth of S. aureus, where the higher the concentration, the bigger the inhibition of bacterial growth.

Keywords: Sweet potato, Ipomea batatas Poir, antibacterial lotion, Staphylococcus aureus.


 

ABSTRAK

Daun ubi jalar ungu (Ipomoea batatas Poir) mengandung flavonoid, saponin dan polifenol yang mampu memberikan efek antibakteri.
