Abstract: A high performance liquid chromatography (HPLC) method was developed for determining β-carotene in 15 vegetables. β-carotene was extracted from vegetables by ultrasonic-assisted extraction, separated on a kromasil C18 column (4.6 mm × 300 mm, 5 μm) using a mobile phase consisting of methanol-tetrahydrofuran (THF)-butylated hydroxytoluene (BHT) (9:1:0.01, V/V), and detected with a UV detector at 448 nm. The proposed method was characteristics of short running time (21 min), sensitive detection limit (0.075 μg/mL), excellent linear relationship (R2=0.9997) and high precision (97.84% average recovery rate). Moreover, this method provided an effective strategy to prevent the oxidation of β-carotene in fresh vegetable samples.
