In Vitro Screening of Medicinal Plants Used in Mexico as Antidiabetics with Glucosidase and Lipase Inhibitory Activities

Table 2

α-glucosidase the 10 most active medicinal plants used in Mexico for diabetes treatment.

Scientific name	Local name	α-glucosidase % inhibition (0.5 mg mL^−1)	IC50 (μg mL^−1)
Artemisia absinthium	Ajenjo	45.0 ± 1.7	n.d.
Achillea millefolium	Milenrama	22.9 ± 1.7	n.d.
Calea ternifolia	Prodigiosa	39.8 ± 2.1	n.d.
Camellia sinensis *	Te Verde	67.3 ± 0.8	299
Iostephane heterophylla	Zacapal	51.4 ± 2.5	509
Ludwigia octovalvis	Clavillo	61.3 ±1.4	202
Ricinus communis	Higuerilla	43.4 ± 2.4	n.d.

n.d.: no determined, *reference plant drug control. Percentage of α-glucosidase inhibition was calculated at 𝑡= 10 min as 100% reaction, whereby the reaction = (mean free glucose in sample/mean free glucose in control) × 100.
