Abstract

Infections are commonly treated using traditional medicine, especially made of natural ingredients such as plants. The use of medicinal plants for complementary or alternative traditional medicine, increases. Medicinal plants are considered to have fewer side effects when compared to chemical-based drugs. Apart from that, low price and accessibility are two aspects that medicinal plants contribute to be traditional medicine. One of the medicinal plants is avocado seeds (P. americana) which has the potential to be an alternative source of antibacterial ingredient. This study tested the inhibition power of avocado seed extract for the growth of E. coli and S. aureus bacteria; furthermore, it determined levels of phytochemical compounds (tannins and flavonoids) in avocado seed extracts. The experimental design used in this study was Completely Randomized Design (CRD). This study involved four types of avocado seed extract concentration: 10%, 15%, 20%, and control. Data analysis was carried out quantitatively using a computer statistics program (SPSS 22.0 for Windows). To test the normality of the data, the Kolmogorov-Smirnov test was carried out; if the data were not normal, the Kruskal Wallis test was carried out. To see the homogeneity of the variance, the Leven's test was employed. The effect of the treatment was tested using the One-way ANOVA test. If the test showed a significant result, the process was continued by the performing Duncan's multiple range test with a confidence level of 5% (p < 0.05).
