Winged beans are an important natural source of some micronutrients. This paper presents the first complete characterization of folate derivatives including polyglutamyl 5-methyltetrahydrofolate (5-CH 3 -H 4 PteGlu n ), folate species and total folate accumulating in pods and immature seeds of winged beans from 9 cultivars and 7 growth stages. 5-CH 3 -H 4 PteGlu n and folate species were determined with a UHPLC-MS/MS method. Accurate determination of 5-CH 3 -H 4 PteGlu n and folate species was optimized and validated according to EMA guidelines including method selectivity, sensitivity, linearity, accuracy, precision, matrix effect and carry-over. The level of total folate is in the range of 73-200 μg/100 g in the pods and 33-61 μg/100 g in the immature seeds. The predominant folate species in winged beans is 5-CH 3 -H 4 PteGlu 1 . 5-CH 3 -H 4 PteGlu 5 is the major polyglutamyl folate derivative. The level of total folate is increased about 4 fold with advancing maturity. For pods, the chain length is increased with growth which shifts from 5-CH 3 -H 4 PteGlu 1 in the early stage to 5-CH 3 -H 4 PteGlu 5 and 5-CH 3 -H 4 PteGlu 6 in the 7th stage. Our findings demonstrate that winged beans are good source of folate. The validated UHPLC-MS/MS method allows for the determination of 5-CH 3 -H 4 PteGlu n and folate species from other vegetable matrices.
