Kaurenoic Acid from Aralia continentalis Inhibits Biofilm Formation of Streptococcus mutans

Table 2

The pH of S. mutans cultures that were incubated with various concentrations of KA.

Conc. (𝜇g/mL)	pH (before incubation)	pH (after incubation)
Control	7.20 ± 0.05	5.03 ± 0.05
1	7.20 ± 0.05	5.00 ± 0.10
2	7.13 ± 0.05	5.00 ± 0.00
3	7.20 ± 0.05	5.13 ± 0.11
4	7.00 ± 0.00	6.97 ± 0.05*
0.1% NaF	7.20 ± 0.00	7.00 ± 0.00*

Each pH value is represented as mean ± standard deviation. *𝑃<0.05 when compared with the control group after incubation.
