Inhibition of α-amylase activity (%) by the labdanum absolutes and fractions added at 1 and 0.5 mg/mL.

Sample	α-Amylase Inhibition (%)
	1 mg/mL	0.5 mg/mL
Adl *	19.77 ± 0.95 b	12.50 ± 1.58 b
Zam	n.a.	n.a.
Dit *	39.99 ± 2.77 a	29.82 ± 0.92 a
Flv *	3.43 ± 0.10 c	4.60 ± 0.10 c

Values presented as mean ± standard deviation (n = 3). Dit and Flv are fractions of Adl absolute. Different coefficient letters mean statistical differences between values within each column by the post hoc Dunnett’s T3 test (p < 0.05). Symbol (*) means a statistical difference between the two tested concentrations for each extract by t-test with Welch’s correction (α = 0.05). n.a. means no activity compared to the control.
