| Abstract: | Tocochromanol composition was analysed in the seeds of nine various fruits: apple ( Malus domestica Borkh.), red currant ( Ribes rubrum L.), gooseberry ( Ribes uva- crispa L.), grape ( Vitis vinifera L.), pomegranate ( Punica granatum L.), Japanese quince ( Chaenomeles japonica (Thunb.) Lindl. ex Spach), sea buckthorn ( Hippophae rhamnoides L.), watermelon ( Citrullus lanatus (Thunb.) Matsum. & Nakai) and canary melon ( Cucumis melo L.), recovered from by-products of fruit industry. The concentration range of subsequent tocopherols (Ts) and tocotrienols (T3s) was as follows: 1.29-29.30, 0.00-11.68, 0.42-95.11, 0.00-7.66, 0.03-5.03, 0.00-0.18 and 0.00-6.68 mg/100 g of seed dry weight for α-T, β-T, γ-T, δ-T, α-T3, β-T3 and γ-T3, respectively. The δ-T3 was not detected in any of the tested seeds. All tocochromanols were successfully separated by rapid RP-HPLC/FLD method and confirmed by the RP-UPLC-ESI/MS technique.
