【 摘 要 】

Antibacteria, a subtance inhibiting the growth of bacteria, can be obtained from tropical-almond (Terminalia catappa), morinda (Morinda citrifolia), and white leadtree (Leucaena leucocephala) plants, since the plants have phytochemical content functioning as antibacterial agent. Commonly, part of plant that contains higher antibacterial substances is its leaf. The objectives of this study were to determine antibacterial activity of tropical-almond, morinda, and white leadtree leaves extracts, and to analyse the potency of the three extracts as natural bactericide for soaking of skin or hide. The responses measured in this study were phytochemical contents, total flavonoid, tannin content, the inhibition zone, the minimum inhibitory concentration (MIC), and the minimum bactericidal concentration (MBC). Phytochemical contents containing the three leaves extracts were alkaloid, flavonoid, tannin, saponin, phenolic, and glycoside. Total flavonoid and tannin contents of the three extracts were tropical-almond extract of 1.14 % and 1.51 %, respectively; morinda extract of 0.61 % and 0.36 %, respectively; and white leadtree extract of 0.60 % and 4.82 %, respectively. White leadtree leaf extract gave the highest inhibition zone against B. subtilis, S. aureus and E. coli, i.e. 1.50, 1.3, and 1.65 cm, respectively; and the lowest MIC and MBC against B. subtilis, S. aureus and E. coli, i.e. 1500, 3000, and 1500 μg/ml, respectively. Therefore, the white leadtree leave extract had more potential as bactericide for soaking of skin or hide compared to those of the tropical-almond and morinda leaves extracts.
