Table 1.

Acceptance of bait containing different concentrations of triptolide fed to male R. rattus in laboratory for 5 days in no-choice feeding test.

Groups (n = 6 each)	Concentration in bait (%)	Body weight (g)	Acceptance of treated bait over plain bait (%)	Total ingestion of triptolide (mg/kg bw)	Mean daily ingestion of triptolide (mg/kg bw)
I	0.0	152.5 ± 21.9	—	—	—
II∗	0.1	155.0 ± 20.6	93.0 ± 5.7a	53.6 ± 7.6a	10.8 ± 1.5a
III	0.2	145.0 ± 15.0	78.8 ± 2.6b	102.2 ± 10.3b	20.4 ± 2.1b
IV	0.3	185.0 ± 30.8	75.9 ± 16.8b	113.0 ± 15.4b	22.6 ± 3.1b

Values are mean ± SD, n = number of rats, and N = number of days. ∗One rat died at the end of treatment. Values with different superscripts a–b in a column differ significantly at P ≤ 0.05.
