Larvicidal Activity against Aedes aegypti and Chemical Characterization of the Inflorescences of Tagetes patula

<div>CE-UV electropherogram of the n-butanol fraction of Tagetes patula. Experimental conditions: 80 mmol/L borate buffer at pH 8.80 with 10 mmol/L Me-β-CD; uncoated fused-silica capillary column, 60.2 cm (50 cm effective length) × 75 μm i.d.; 30 kV; 25°C; hydrodynamic injection 0.5 psi × 5 s; detection at 214 nm; BF: 500 μg/mL. Peaks: (1)  Tp2 (patulitrin);  (2) Tp1 (patuletin).</div>
